A few days ago our believed to be American Pitbull Terrier mix had puppies by our Great Pyrenees. I was wondering at what age should I start introducing them to the chickens and goats so they'll be used to them when they're older. Our Pyrenees is wonderful with them now, but killed our ducks when he was younger. The Pitbull is okay as long as the chickens don't get out, but the goats hate her. Soooo, how can I teach the puppies or puppy to not chase the chickens from a young age? Any questions are welcome.
