Some sort of hound mix. He may have a touch of Basenji as the coat color & tail set are suspicious, but that's not a common breed in this area. However, since a "pit bull" is not a breed, but rather a generic term for several different & distinct breeds (the American Pit Bull Terrier, American Staffordshire Terrier, Staffordshire Bull Terrier, American Bulldog, & Bull Terrier), it would be hard to know. And many other breeds have similar musculoskeletal characteristics.
However, thanks for adopting him. He's a cutie.
