Dog Breeds Medium To Large

What is a large and medium dog breed that is excellent with cats???
I mean NO funny business with the kittens! I'm not looking for a dog, but a friend is. Greyhounds are? She hates small dogs like poodles and Chihuahuas and loves dogs like greyhounds, Collies, Huskies, and Old English Dogs pastor. It must be absolutely comfortable with something to do with cats, kittens excluded-like whistling, running, purring … Thank you!
Honestly, everything depends on the dog. I'd like to get one that is not understood for hunting or grazing. All dogs have the instinct to hunt something that works, there is not a race. Just make sure that the dog has had prior involvement with cats if possible, or to test the dog to the early days. And taken. www.petfinder.com
