How to stop your cat from attacking your dog
Get a cat tree.
A cat tree will provide your cat a safe haven from the attentions of your dog. Cats often attack dogs to get the dog to leave them alone, so providing a spot where your cat can nap in peace is essential for maintaing good pet relations.
Place the cat tree in an area that is often frequented by both pets so that the cat can choose to climb to its hiding spot instead of attacking the dog. Make sure that the dog can't get to the cat when it's in the cat tree.
