Hello, So, we have a new 2 month old puppy who is very attentive, smart, and people oriented. He is a Springer Spaniel which is a type of bird dog. While we would enjoy being able to take him pheasant hunting, he has been attacking our 3 chickens and duck. He hasn't killed any, but he does pounce on them, chase them, and has pulled out feathers. He's a puppy. Normally, we keep him on a leash when the chickens are out and let him off after the chickens are locked up. However, are there any gentle training methods that might help him understand that he cannot chase our chickens? We have other dogs (Beagles) who can drink out of the same water bucket as the chickens and not bat an eye. They were later trained to chase rabbits, but they didn't bother the chickens as puppies either. Thank you!
