I have two whippets, my Mum has beagles, a golden retriever and a standard dachie. They all get along, a few incidents but never anything major. I also have foster dogs through here, I have had beagles, greyhounds and at the moment have a blue heeler. again never any major issues. I think that it doesn't matter so much to the breed but more to the type of personality that your dog has and matching the same type of personality.
