Does the Breeder Make any difference?
A reputable breeder will research back through many generations of pedigree and attempt to produce the healthiest and most well tempered litters possible. If a breeder can not produce official results of hip testing (such as OFA) and eye tests (such as CERF) or the Sire (father) and Dam (mother), then walk away. The knowledgeable breeder will generally also have information of the history of the line of the Sire and Dam which includes these and other genetic information. This would include litter mates in several generations back. Fortunately the breed does not have a high occurrence of problems in this area, but statistically there is always a chance.
