T find out if the local pet shops in your area support puppy mills just go here to this interactive map and put in your zip code. It will give you a listing of all the pet shops in your area that do and don't support puppy mills. The red check means they do and if they have a red check...don't buy anything from them. Here's what I found out.
The Petsmarts and Petco's that I go to do not support puppy mills but the Mall pet shop on Meadows Lane does. Not a real big surprise there and I refuse to shop in Mall pet stores.
It's good to know that Petsmart and Petco don't buy puppy mill puppies. I also know from experience that they get their rats, hamsters and mice from regular people who either breed them or accidentally have a litter and want to adopt them out.
The Petsmart I went to when I had baby hamsters, sexed all the babies for me for FREE...and told me that would adopt them out if I wanted them too. But I decided to keep them and the manager told me that's how they get their small animals most times.
I buy most of the supplies from Petsmart through Amazon now and it's good to know they don't support puppy mills.
