Get a sighthound like a whippet or lurcher. They are some of the most healthy and relaxed dogs you can get due to the amount of outbreeding done to keep them fit for racing or coursing. They are one of the few "breeds" where pedigree breeding practices is frowned apon. Plus the risk of negative breeds being mixed in is minimal as hyper agressive breeds like pitbulls do not conform to a sighthound frame so they are easy to weed out. If you are fine with rescues there are also tons of ex-racing hound kennels with greyhounds to choose from.
