If your cats have had exposure to dogs, a Golden Retriever would be good, But the variable in the mix are the cats. Cats don't adapt to new dogs well. If they have been raised with the dog (from kittenhood) then normally a cat will be able to adapt to a new dog. But if they've not been exposed to living with a dog, it's not really likely they will ever truly accept the dog, they will merely tolerate it. Some cats may never even do that much (tolerate).
