So even if a dog has a very high prey drive, it can be controlled? It's not a genetic drive that varies in degree from dog to dog? He did crunch a squirrel in half at a few months old after going potty in the backyard.
My male has high prey drive and he redirected on me once when I first got him. He was about 8 months old. He was also reactive on a leash. I spent hours at the park just watching the world go by with him. I wasn't training him not to chase these things but he was exposed to it, while I was working on his dog issues. Keeping your dog away from it is not going to help him IMO. You have to get him out there and teach him.
