Adding a dog to a home that already has a cat, or the other way round, goes better when the dog's instincts are on your side. This list collects the breeds whose editorial ratings suggest they are the easiest to introduce.
Every breed here scores 4 or 5 on Good with cats and 3 or lower on Prey drive in our editorial ratings; the list is ranked by the Good with cats score, then popularity. The second condition matters as much as the first. A friendly dog with a strong chase instinct can live peacefully with the cat it knows and still bolt after the neighbor's; the prey-drive cap keeps most sighthounds and terriers off this list even when they get on with their own household's cats.
The Pug is the only recognized breed to score a 5. Behind it are the Cavalier King Charles Spaniel, Golden Retriever, Havanese and Bichon Frise, plus a few big, soft-tempered giants such as the Newfoundland.
The rating is a tendency, not a guarantee. A dog raised with cats from puppyhood usually does well regardless of breed, and a dog of a cat-friendly breed that has never met one may still chase at first. Introductions should be slow, with the cat given a room the dog cannot enter. The same applies when a dog from this list stays in a sitter's home with a resident cat, or when you book cat sitting for a household that also has a dog: the breed page is where to start, but the sitter still has to meet both animals before the first stay.
