Cats and dogs are like apple and oranges. Unless both kittens and puppies are very young when introduced to eachother you can never expect to just bring a kitten into a home with any dog without anticipating some animosity. Or vice versa. Especially if neither species has ever had any contact with the other. Kittens will react with their fur up, spit or run, at the first sight of a dog because it is afraid. This reaction then triggers a defence or prey response from the dog and the chase or fight is on. If introduced slowly, I have seen many dogs aggressive toward cats come to like like them. Much of it depends on the cat's willingness to to befriend the dog as well. Dogs will chase and hunt a cat that runs or fights, but will most likely leave a cat or kitten alone that is submissive and passive. If introduced slowly and allowing time for each to get to know eachother, they can become friends. If the kitty shows any signs of fear, by growling, spitting, claws out, and such, then it is not ready to accept the dog and the dog will see that as something to protect you from, or a game, or prey and it would be dangerous to leave them together. I want to clarify, I am in no way advocating keeping a kitten a dangerous situation if your dog has already killed one. And, what I am saying does not necessarily work in every situation. If you are not prepared to protect the kitty and introduce them correctly taking the time necessary to do so, then maybe the kitty needs a new home.
