Dogs are capable of forming deep bonds with all sorts of animals. Livestock guarding dogs like Great Pyrenees and Anatolian shepherds are bred to guard helpless livestock and will have a better chance of learning to like a rabbit than a hunting breed like a hound or terrier. That said, all breeds can and have learned to like small prey animals. Dogs have a better chance of success if they start young and if they are mellow by nature. Not all dogs can learn to like a rabbit, so be realistic as you plan your training goals.
