On Thursday, I had the opportunity to attend an online seminar put on by Maddie’s Fund. I was already interested in the topic, but expected to learn little new as I had already been reading up on the topic on my own. As it turns out, I learned a heck of a lot more information in the seminar than in the newspapers. Go figure.
The topic? What Animal Shelters Need to Know About the Canine Influenza Outbreak. The seminar was presented by Dr. Sandra Newbury from the University of Wisconsin-Madison School of Veterinary Medicine and UC Davis Koret Shelter Medicine Program. Dr. Newbury has been working closely with shelters since the outbreak and was able to share some details that the media has missed in their rush to join the hype.
She shared some of what shelter workers who have been dealing with after the spread of this virus, not only in the shelters in Chicago, but also in the surrounding areas and states. Wow. I cannot imagine the stress. They deserve our support. What they are dealing with is incredibly overwhelming. I imagine they are exhausted after managing through this for the past two months. They are not only caring for hundreds of sick cats and dogs, but also worrying about exposing their own pets to this virus. Imagine how scary it must be for them.
You can get a copy of the presentation handout here, but I thought I would share a few of the things I learned.
- The virus currently making dogs sick in Chicago (H3N2) originated in Korea, China and Thailand. It is suspected it came from the Avian influenza and transferred to cats and dogs. In Korea, China and Thailand, the virus also infected cats, who experienced a significant mortality rate when infected (something we have not seen here).
- Despite what we may think, there is no proof that the virus came in with a dog imported from these countries to the United States. They may never know how it made it to this country.
- The virus did not originate in a shelter, but started with one dog living in a home. Contraction of the virus most likely started in a training class, vet clinic, or doggy daycare.
- When it did hit animal shelters in Chicago, it hit them like a tidal wave. Example: One or two dogs started showing symptoms on Monday. By Tuesday, ten dogs were sick and by Friday, shelters were seeing 50-100 dogs sick. In CACC, they saw 200 dogs sick with the virus.
- Most of the dogs have had mild to moderate respiratory disease. Very few that have died, but some have developed pneumonia and needed additional treatment.
- Symptoms usually start with a cough and nasal discharge. Dogs sickened with this virus seem to feel worse than the dogs infected with the known virus, H3N8.
- This virus differs from the one we have previously seen in the United States (H3N8) in that it has a longer “shedding” period (the virus can still be shed by the formerly sick dog long after they seem well, thus making them still contagious after 19 days).
- This has had a huge impact on shelters and shelter workers. Because of the longer shedding period, shelters have had to stop or slow down the release of dogs to rescues and they have had to turn some dogs away in order to avoid infecting more dogs, sometimes diverting incoming dogs to other uninfected shelters. They are trying to be very, very careful to not spread the virus.
- Because this virus is new to the United States, many shelters were placing dogs up for adoption after seven days, when they appeared well, but they soon discovered that other dogs were getting infected when exposed to these dogs even though they (the formerly sick dogs) were well.
- Dr. Newbury said they are now recommending that dogs be isolated for at least 21 days after they were first diagnosed to prevent spread of the disease, but she cautioned that they are not yet positive that 21 days will be long enough, because they thought it would be fine after 14 days and discovered it was not.
- If a rescue or animal shelter chooses to adopt out a dog who was sick and no longer has symptoms, they should be apply two rtPCR tests and get a negative result from both before allowing the dog to be adopted, and even then, they should gain agreement from the adopter that they will keep them isolated for the full 21 days (no dog parks, no training classes, etc.).
- Shelters in Chicago are developing plans to release some dogs from their shelters to avoid an increase in euthanasia, but they are giving rescue groups very, very specific instructions on holding the dogs in isolation and away from other dogs. They do not want to move dog to an area that does not have influenza already.
- Sick dogs are not turning over to recovering dogs as quickly, but they are starting to see more recovered dogs than sick now. That is very good news.
While I still think this is a very serious outbreak, I feel better knowing more of the details. The speed at which this virus spreads and the fact that the shedding period is so long should be a concern for rescues as they import dogs from these sates. They may want to avoid the ones where cases already been confirmed for now.
Kudos to all the shelter workers dealing with this and trying to make sure it is contained. You have a tough job on normal days. This is above and beyond what is “normal.”
I’ve been stewing on this issue for some time now, but the recent outbreak of canine influenza in Chicago, and some of the recent stories I have heard about dogs transported here, has led me to believe it is time for Minnesota to regulate the transport of rescue dogs into our state.
I know it is odd for a rescue supporter and pet adoption advocate to suggest such a thing (I have no doubt it will be considered blasphemy by many local rescues), but I come at this as more than just a supporter of rescues. I come at this as a pet owner, an owner with senior dogs, dogs who have had recent health issues. I come at this as an owner who has seen rescues, acting in the best interest of the rescue dog, make critical but unintentional mistakes that have the potential to harm the dog populations that are already here.
From a lack of proper foster parent training and education to a lack of proper care for sick dogs with the potential to expose other dogs to illness, rescues have the potential to cause harm to existing populations of dogs in our state.
Just last month, a group of dogs were transported in from another state and placed in foster homes (after an urgent call went out for people to foster) with little being said about the health checks these dogs received before they were handed off to their new foster homes. I know that the situation was an emergency, and that rescues had little time to act, but I wonder if they gave any thought to what they might be transporting in with them before they drove them across state lines? Were the potential dangers considered beforehand? Did they get a full health assessment and blood workup done before they handed the dogs off to their foster homes?
More diligence must be taken, especially in light of hearing that the canine influenza was likely imported with a dog that came from China or South Korea and that Canine Brucellosis was recently transported into Calgary, Alberta, Canada via rescues in the southern U.S. and Mexico. I wholeheartedly support saving dogs, but we need to be more diligent. We need to be more thoughtful and plan ahead. We need to make sure we are not saving one dog while putting a whole population of resident dogs at risk.
In New England, the south to north dog transport (i.e., rescue transports from southern shelters to northern rescue groups) got so big that veterinarians became concerned. They started seeing more cases of parvo, rabies, heart disease and other dog diseases and parasites as a result of the dogs being brought into their states. Massachusetts was the first to implement laws around dogs being transported into their state, but others soon followed including New Hampshire, Rhode Island and Connecticut.
To circumvent the Massachusetts regulations, officials say, some rescue groups simply told adopters to meet them over the border. New England was caught in a geographic game of Whac-a-Mole, trying to ensure that only healthy dogs were being transported by responsible rescues. Dr. Scott Marshall, the state veterinarian in Rhode Island, says that state saw parvo cases blossom from two or three each year into two or three each week in recent years before enacting regulations that mirror the Bay State’s. Today, all the New England states have rules. Boston Globe, May 12, 2013
The laws in New England require:
- Rescues register with the state
- Each animal have a health certificate that is signed by a veterinarian
- Imported animals be held in isolation for 48 hours in an approved facility to allow dogs to recover from the stress of travel so their health status can be more accurately assessed
- Must be examined by a vet after the 48 hour holding period
I know that implementing something similar in Minnesota will cause hardship for many rescues, at least initially, but I think it is necessary. Importing dogs from out-of-state is such a common event now that regulation is necessary. In the rush to save more dogs, some rescues are choosing to cut corners and worry about the health of the dog once they get here versus before. This is not to say that rescues are bad. They are not. They are in the business of saving dogs’ lives. Their heart is in the right place. But if we are to do it in a way that protects all dogs, both those in and out-of-state, we need to ensure that all groups are following protocols that ensures this is the case.
As always, I welcome your thoughts.
Massachusetts Animal Rescue and Shelter Regulations (initial Draft)
The more you dig into puppy mills, the more you learn about the physical and physiological repercussions it has on the mother dog (and that doesn’t even take info consideration the genetic issues) and her puppies.
Last fall, when Dr. Frank McMillan spoke at an event (hosted by Animal Folks MN), he shared some data on the behavioral issues that show up in puppy mill puppies sold in pet stores. The results were quite startling:
- Out of 14 behavioral variables measured across puppies from responsible breeders and those sold in pet stores, the pet store puppies were found to have fared worse in 12.
- As they grew up, pet store puppies showed more aggression towards their owners.
- Pet store puppies also displayed more aggression towards other dogs.
- Puppies who are purchased in a pet store are more likely to escape and run away.
- Pet store puppies tend to be under-socialized because they are taken away from their mothers too early and are likely to experience trouble as they grow up.
You can read more about Dr. McMillan’s study via Penn State here: Penn Vet study finds pet store puppies come with increased risk
Puppy mill breeding dogs have their own set of behavioral issues – almost all due to a lack of socialization and fear and ongoing abuse, but now we can show that the puppies they bear have problems too. Why is this the case?
New evidence suggests that mother dogs experiencing extreme levels of stress can pass that stress on to their puppies, and that stress can impact their lives long after they have been weaned and adopted into loving family homes.
The body is designed to protect the puppies from normal amounts of stress:
“Normally, an enzyme inactivates cortisol at the placenta, protecting the fetuses from the level of cortisol that the mother is experiencing. But when the cortisol level is extremely high, some passes through the placenta to the developing puppies. They receive the extra cortisol as information: The world is scary. We should be prepared. “
You can read more on this in the Whole Dog Journal from their November 2014 issue, titled “How a Mother’s Stress Can Influence Unborn Puppies: A highly stressed mother dog may influence her unborn puppies and affect their adult behavior.”
That pet store puppies are more likely to carry this stress message in their systems should not be all that surprising. After all, past evidence has shown that the stress of the mother passes down to the baby, both in humans and rats.
Puppies born in mills experience the stress of the mother in utero and after they are born. When you add in the fact that they are then pulled away from their mothers at a very young age, shipped across country in trucks with other sick little puppies, manhandled and placed in a pet store window, where they are on display and handled over and over again until they are adopted, it’s a wonder any of them survive, much less make it into a home as a normal dog. That they fare poorly on 12 of 14 behavioral variables should not be surprising either. It makes one wonder why anyone would want a dog from a pet store at all.
Daisy’s last litter of puppies were kept by the organization that saved her life. They were going to be trained to be service dogs. I wonder how many of them failed to make the cut? I hope not many, but the more and more I learn about puppy mills and their impacts on the dogs and their offspring, the more I believe that they were doomed from the start.
Now how sad is that?
This past week I read a really great piece that was posted on Facebook by 4Paws University. It was a powerful message and one that seemed to resonate with people (it had over 900 shares, 930+ “Likes,” and so many comments I had to quit counting. You can read the actual posting here: BONE TO PICK: THE RUSH TO ADOPT THE SAD STORY DOG.)
The post has to do with America’s penchant for the “sad story dog.” You know the dogs I am talking about, the ones that come from a sad situation, get shared in the media, and generate a mass swelling of people who want to adopt the dog and “save” them. It happens time and time again.
You and I have both seen those individual stories of that one dog who was abused and saved, or the dog who ended up in a serious, life-threatening situation and suddenly needed a home. But the most common situation you and I see is the one where there is a mass rush to adopt a dog after it has been rescued during a puppy mill raid. Stories like these make the local (and sometimes national) news. The pictures and video are usually heart-rending. People follow the story closely. When the dogs are ready to be adopted, there is usually a big media campaign to let people know about them and to encourage them to adopt.
None of this by itself is bad, but what gets missed is that some of the people wanting to “save” the dogs involved in the sad dog story are not always the “right person” for the dog and his/her needs. People who are drawn to a hard-luck story may be motivated by different reasons, and not all of them are motivated by the right reasons.
When foster Maggie and her fellow puppy mill friends were rescued, there was a lot of media attention around the raid and the care of the dogs. The facility that cared for them was flooded with adoption requests. I could not help but wonder the motivations of those who wanted to adopt a puppy mill dog. It wasn’t like this facility didn’t have dogs available for adoption before the raid, or that they ran out of dogs after the raid. So what motivated the people to adopt when they had not done so before? Was it the hard luck story? Did they see themselves as the hero in that story (rushing in to “save” the dog)? Or, did they want a certain breed that was rescued in the raid? Were they already looking for a dog and this just happened to be the right moment? Or, did they just act on impulse and get a dog with a story?
All too often we are motivated by the sad story dog without knowing a lot about what a commitment it is or whether the dog is a good fit for our family or lifestyle. Too many of these dogs are getting swooped up by emotion and being left behind by reality. Some of Maggie’s fellow puppy mill survivors have been re-homed, lost or discarded because the people adopting them did not know what they were getting into. They did not understand that the sad story dog they were getting was one that required work, time, patience and in many cases, another dog, to help them to start to live a normal life.
As adopters, we need to take more time to do our research. It’s great that people are excited and want to help by adopting a sad story dog, but we need to understand our motivations for adopting and recognize if it is a good fit. As rescuers, we need to be more diligent about who adopts a sad story dog. Rescuing a dog from a sad situation is not enough. We need to make sure that where they land is the safe landing we want for them too.
Sad story dogs will continue to come along. We just need to be prepared to ask the questions that will ensure it lands in the right home.
Having a pet become lost can be so devastating. Whether it be a cat or a dog or a bird, the loss is still the same. The fear and the pain one feels is overpowering. Sometimes it can be difficult to act because we are so immobilized with fear.
There are so many things that can stand in the way of being reunited with a pet, but among them are:
- Not having your pet microchipped.
- Waiting to spread the word. Hoping that he/she will come back in an hour or two.
- Driving around the neighborhood instead of handing out flyers and getting the word out.
- Not calling the police, shelters and vet clinics in the area to alert them that your dog is missing.
If you live in St Paul and Minneapolis, Minnesota, and you do not do any of the above, you STILL might be lucky enough to be reunited with your pet. Why? Because Minnesota has a five-day stray hold that requires pets be held at the animal shelter for at least five days to allow an owner to claim them.
And even if you don’t get them after the five-day hold, your pet may still survive because a rescue was able to take him in or the shelter was able to put him up for adoption.
But if you live in Chicago and your pet goes missing, you better hope and pray you have a lot of luck on your side. Why? Because Mayor Rahm Emanual, and the City Council did something pretty low down and dirty. They introduced, and passed, an ordinance to reduce the stray hold in Chicago from five days to three for dogs and zero days for cats.
YES, I said ZERO DAYS for CATS.
Not only did they reduce the stray hold time for dogs and cats, but they also reneged on their promise to do an information campaign to inform Chicagoans about the change. Thus, most Chicago pet owners have no idea that their lost pets could be killed before they even have a chance to find them.
And, if you have a cat? Good luck. Chicago Animal Care and Control (CACC) will most likely have killed it by the time you start looking. Remember, cats have ZERO days to be saved.
So unless your pet is microchipped and you spread the word immediately that he or she is lost, you may never see your lost pet again. Ever.
Feeling a little pissed off? Good. Because I need you to let the mayor and his friends on the council know how you feel about them choosing to reduce the chances of an owner and their pet being reunited.
There is a petition posted on Change.Org demanding that the Mayor, the City Council and CACC revisit this resolution and reconsider the reduction in stray hold (Thank you Lost Dogs Illinois for the heads up!). They also demand the Mayor and City Council inform the citizens of Chicago about the change.
Let’s tell Chicago Mayor Rahm Emanuel and the City Council what we think about them killing lost pets.
- Please sign the petition: Revisit the resolution reducing the stray hold for dogs and cats in the City of Chicago.
- Tweet the Mayor (@ChicagosMayor) and let him know what you think of his decision to sneak this ordinance change through the Budget Committee without informing the public of the change.
- Post your concern on Facebook on the Mayor’s home page.
- Spread the word so more people sign the petition and tweet the mayor. Share! Share! Share!
And one more thing, get you pet microchipped. NOW.
Don’t wait for CACC to tell you it’s too late and they already killed him.
Millennials, the group that is expected to surpass Baby Boomers as the largest generation this year.
And it’s not just the pet industry that is taking notice. Almost every major company inside and outside of the United States is doing the same thing. Why? Because unlike generations past, millennials have influence. It’s not just their sheer size (in numbers) that is powerful, but also their reach. Millennials are more socially connected and more socially influential than any other generation. They are also ethnically and racially diverse, well-connected, technically proficient, and early adopters. They are unlike any other generation that has preceded it. They are the movers and shakers who will be impacting our world for many years to come, much like the Baby Boomers did in previous years.
With a generation this large and influential, it only makes sense that they would impact the pet world as well.
The American Veterinary Medical Association (AVMA) recently published a report on how millennials will change the way veterinarians do business. In “The Generation Factor: How the rise of the millennial generation could mean changes in the way veterinarians do business”, they laid out the differences between Baby Boomers, Gen Xer’s and Millenials, not only as clients but also as employees. The differences are quite distinct. For instance, the work ethic for Baby Boomers has to do with how many hours worked, while Gen Xer’s are about working smarter (not harder), and millennials are all about tasks completed and getting feedback and gaining consensus.
I am sure many animal welfare groups are taking notice, but I wonder if smaller, local shelters and rescues are as well? I hope they are because there is another reason that the pet industry is taking notice of the millennial generation – they think pet ownership is going to decline with them.
This means more competition between those who are selling pets and those who are adopting them out, and the adoption side may be facing an uphill battle.
Why? Because millennials are more likely to:
- Rent than to buy a home – This means more apartment and condo dwellers, the residences least likely to allow a pet.
- Move frequently – More than any other generation, which makes it harder to care for a pet long-term.
- Stay in college longer – Millennials have had a tough time in the job market due to the poor economy, so more are choosing to stay in college longer and get their masters degree or a doctorate. Owning a pet and going to college is also a possible deterrent.
- Be impulse buyers – They are less likely to wait and go through an extensive adoption process to get a pet.
- Purchase a pet from a pet store or breeder (including online) rather than adopt a pet from a rescue or a shelter – According to a recent survey by Best Friends Animal Society, by almost 50%.
- Believe that animals can safely stay in shelters until they are adopted – 38% of millennials vs. 28% of the total population.
No wonder the pet industry is worried.
All hope is not lost however, millennials are also more likely to get a pet earlier in their lives compared to boomers (21 years old vs. 29 years old), be single longer (and thus, may seek a pet for companionship), and are more civic-minded and more likely to get involved tomato a difference..
Rescue groups have an opportunity to make a difference now. If they are not doing so, they should start working to build a relationship with millennials in their community. Organizations need to be inclusionary and seek their input. They should also be open to new and innovative ideas on how to improve the organization, increase adoptions and connect with other millennials.
Other ways rescue groups and shelters can connect with millennials:
- Have a strong social media presence (Facebook, Twitter, and Instagram, etc.) and be actively engaged with followers.
- Make your website and social media platforms a place where millennials can get information and learn something new that can help both them and their pet. You need to be the online expert they go to when they want advice and support.
- Connect on a person-to-person basis. Two-way communication is important to them.
- Be open to texting and responding via social media platforms. Millennials are less likely to use email.
- Make what you provide, and what they are getting from you, is distinct and different. You want it to be share-worthy.
- Be more customer-service oriented. Millennials are individual social media companies of their own, so what they experience with you will be shared with their network of friends and family.
- Recognize their efforts frequently. Acknowledge the work done and the benefits experienced by the organization.
- Appeal to their desire to make a difference. Adopting a pet needs to be less a sob story and more of a motivator to do good.
Despite some of the concerns about pet adoption declining, rescue groups and shelters should be very excited about the impacts millennials can bring to the rescue community. Their innovative and creative ideas, combined with a dedication and desire to help, has the potential to make a real difference in animal rescue.
I know one millennial animal rescuer who is making a difference on a daily basis here in Minnesota. I am often in awe of her ability to motivate people and get them involved in rescue. She is well-connected, uses social media extensively and has saved more dogs and cats than anyone I know. She is a force to be reckoned with. Just imagine what could happen if we had 100 more people like her.

These is the question I have been asking myself for a few days now, ever since I first read the article in The Princeton Union-Eagle (Warning: It is not for the faint of heart) detailing the beating, torture and killing of a dog named Draco by a man named Anthony (Tony) Sather.
I have always assumed that someone who kills or mutilates animals is a serial killer in the making. They have been linked in my mind for as long as I can remember. Killing animals = serial killer. But is it really the case?
- Someone who commits an act like this is a serial killer in the making and they will progress to killing a human being down the road.
- A person who does this is not normal and never will be.
- There is just something wrong in the brain of someone who kills animals and they will always want to kill.
- He will do this again and next time it might be a child.
But is it true? Or, are we just assuming it is because of something we saw on T.V.?
I had to find out if what I thought I knew was accurate. So, I decided to do a little digging.
The first piece I found was about children and animal cruelty (written by Joni E. Johnston, Psy.D, in Psychology Today). It turns out that cruelty against an animal can be caused by more than just a bad person or someone who is evil. In fact, according to Dr. Johnston, there is a common thread between children who abuse animals and those who have “witnessed or experienced abuse themselves.” Children who experience or witness abuse are more likely to reenact that violence on animal or pet either as post-traumatic play or in imitation of something they witnessed or experienced.
Dr Johnston shared 13 possible motives for child or teen violence against animals, including post-traumatic play and imitation, but also curiosity. She also wrote:
Every act of violence committed against an animal is not a sign that a person is going to turn out to be a homicidal maniac. Particularly with young children, whose natural exuberance and curiosity can lead to some unpleasant experiences for their pets, it is fine to shrug off an occasional lapse in judgment while continuing to educate the child about humane animal treatment.
However, locking a pet inside a closed space, violently lashing out at a pet after getting in trouble with a parent, or taking pleasure in watching an animal in pain are all “red flags” that signal the need for professional intervention. This is particularly true when the child has the cognitive maturity to understand that what s/he is doing is wrong – and repeatedly does it anyway. “Children Who are Cruel to Animals: When to Worry”, Psychology Today, Joni E. Johnston, Psy.D,
So, not every child who abuses an animal is necessarily a serial killer in the making. That is reassuring.
So, what about adults who were cruel to animals in childhood and continued on into adolescence, as it has been alleged in Anthony Sather’s case? Are they serial killers in the making? In another piece from Psychology Today, “Do Mass Killers Start Out by Harming Pets?,”, Dr Gail F. Melson (Ph.D.) shares some concerning information.
Like Dr. Johnston mentioned in the above referenced piece, Dr Melson acknowledges that children who experience abuse are more likely to abuse animals, but she also shares some additional data:
“In an assessment of 1433 children ages 6 to 12, Ascione found that among abused children, 60% had abused animals.” “Do Mass Killers Start Out by Harming Pets?,”, Psychology Today, Gail F. Melson (Ph.D.)
She goes further and writes that animal abuse is usually the first tell-tale sign of trouble in “adolescent and adult killers.” Even more disturbing, evaluations conducted at state penitentiaries show that “70% of the most violent prisoners had serious and repeated animal abuse in their childhood histories.” In other words, our most violent criminals started first with animals.
However, Dr. Melson also cautions us against assuming a single act is a predictor of someone who will kill in the future and to instead consider a “red flag” that should be examined further. Then there was this piece in Psychology today, which completely contradicted what I had read (and assumed) about animal cruelty and serial killers. According to Hal Herzog, Ph.D., our assumptions about animal cruelty and serial killers are incorrect
“… contrary to popular opinion, most serial killers and school shooters do not have documented history of animal abuse.” “Animal Cruelty and the Sadism of Everyday Life”, Psychology Today, Hal Herzog, Ph.D.
So, being a psychopath (which is often associated with serial killers) does not necessarily indicate prior animal abuse or acts of animal cruelty, but according to a study mentioned by Dr. Herzog, something else does, sadism.
noun \ˈsā-ˌdi-zəm, ˈsa-\
: enjoyment that someone gets from being violent or cruel or from causing pain; especially : sexual enjoyment from hurting or punishing someone
Sadists gain enjoyment from causing pain, but they are not necessarily always a serial killer or vice versa.
So where does this leave us? Does this mean serial killers are out? Does this mean killing an animal does not create a serial killer? Or, that someone who commits a cruel act against an animal is unlikely to do it again? Not necessarily, as discussed in “What Makes Serial Killers Tick?”, there are a variety of factors at play, including: early development experiences, genetics, and a combination of other personality traits like anti-social behavior. Not every serial killer started with animals and not every sadist ends up becoming a serial killer.
However, one thing seems to be certain, someone who has killed and tortured animals as a child, and continues to do so into adulthood, will continue to do so until he/she is stopped. Whether or not that person goes on to kill people is uncertain, and dependent on a wide variety of factors.
However, sadistic serial killers do exist, so the possibility exists that someone who kills animals could become a serial killer is there. Whether or not that person will be one can only be determined by those who have an expertise in psychological personality disorders.
