Pet store puppies: The stress of the mother passes to down to the child
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.

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?
