What can I do about a dog that hates cats. I have a 3 yr. old mixed breed that just goes crazy when she sees my cats. She barks, she makes noises like she is dying, and if on the rare occasion that she gets loose she takes off after the cat. We have not had any bad things happen, because our 4 yr. old Lab protects the cats. It is just a hassle keeping them all separated. Can an old dog learn new tricks?
Probably not. You can talk to a dog trainer but hold your breath. vetcare
