I currently have a Redbone mix right now and have had German Shepherds and Dutch Shepherds for years. My best advice is to get your hound as a puppy, and introduce it to your cats while it is young. Teach it the boundries with the cats while it is young and reinforce them as the pup grows. Also if you are just wanting to have a hound as a pet and not for hunting, if you go to a good breeder you should be able to get a puppy who has a lower drive level than one who is hunting dog level. A good breeder will be able to pick out the puppy that would most likely be calmer. If you are planning to recsue a puppy than you could contact a local Dog Trainer to help you learn about how to test a puppy for lower levels. I do this with my clients who are looking into getting a new puppy and need help finding the right level of energy for their home.
