We did find our Baily at a shelter. So glad we could find him the home he so very much deserves and thanks us for every day, multiple times. Many Pit Bulls are wonderful. But yes, we also saw your same observation.
Thanks for looking good luck. I hope they outlaw those puppy mills. We have local pet supply stores like pet smart that have showings on weekends so you can see the dogs in neutral environments and get a great idea of how they interact with strange people and other animals.
