In general, the Lhasa is a healthy and hardy breed. The most serious hereditary disease in the breed is renal dysplasia, an often-fatal kidney ailment. Responsible breeders do not sell puppies with symptoms of kidney problems, specifically excessive water drinking and excessive urination. However, sometimes symptoms don’t occur until a puppy is older. Be sure that you receive a written health guarantee from your puppy’s breeder. While other health problems such as hip dysplasia are not common, they are more likely to crop up in litters bred by “backyard breeders.” To be sure a breeder is reputable – ask for references.
