How do I get my cats to not attack my dog???

Just give it time with supervision in the meantime. Your dog sounds very submissive and will probably avoid the cats as much as possible. The cats will get used to the dog's presence since the dog doesn't go after it. Hopefully your dog will eventually snap back at the cats to back them off a little so the cats don't push him around too much. If it were me then I'd just supervise them until they strike a balance and at some point I would start putting all of them in the same room while you protect the dog and disipline the cats when they act aggressive. It will just take patience and persistence.

I have the opposite problem. My dog isnt being mean but he plays too rough with the cat, who is not afraid of the dog. I will sit there with both of them on my lap and make them both submit to the other's presense.

Hi,

Despite the cliché about fighting like cats and dogs, it's perfectly possible for the two species to live happily under one roof. However, it's also perfectly possible for a cat to injure a dog, and for a dog to seriously hurt or even kill a cat. To keep your home a peaceable kingdom, you'll want to arm yourself with some know-how before you add a new dog. Here's more info:

That's normal actually. Cats are very hard to discipline. You could try spraying your cats with a water bottle when they attack the dog.

i had 2 cats that attacked dogs...one even attacked a boxer and wouldn't let her in the yard and she was my sisterinlaws boxer...i let them be it was the cats territory they had a right to protect it...the dog finally knew how to stay away from the cats...your cat will let up and accept the dog...mine did...i had a long haired persian and a manx mixed...they was the only animals other than my golden on my property they accepted him but no other dogs or cats...after 3 days the boxer was accepted...

spray the cat with water when he attacks or pick them up and put them in a room by themselves
