All dogs have the potential to develop genetic health problems as all breeds are susceptible to some things more than others. However, the one positive thing about getting a puppy is that you can avoid this as much as possible. A breeder should absolutely offer a health guarantee on puppies. If they won't do this, then look no more and don't consider that breeder at all. A reputable breeder will be honest and open about health problems in the breed and the incidence with which they occur. Health clearances prove that a dog has been tested for and cleared of a particular condition.
