We recently adopted a six month old puppy (husky/cattle dog mix, have had her about two months). Over the last few weeks she has become increasingly OBSESSED with our resident cat (9 years old, have had for 9 years). Any time she sees her (the cat) she goes crazy and chases her endlessly trying to nip and bite until the cat finally is able to jump high enough so she can’t get her. Yes, I know she has herding dog in her & that instinct will be hard to change, but I am at a loss. I don’t know what to do. We have had her in private dog training lessons since we adopted her and none of the methods are helping. We’ve tried a time out room when she goes after the cat, rewarding with a million treats on the rare occasion she doesn’t go after the cat, both of them eating on opposite sides of a gate, reintroduction. I need help. I can’t give up either of them, but need to find a way to have them coexist semi-peacefully. TIA.
