This is a genetic disorder that affects some Keeshonden: the
proportion of 'pet shop' or 'backyard bred' Kees with this condition
is significatly greater than Kees obtained from a reputable breeder.
Simply put, hip dysplasia is a deformation in the hip joint. The head
of the femur does not sit solidly in the acetabulum. The joint lacks
tightness, and the condition results in a painful and often
debilitating life for the dog. Hip dysplasia is considered to be a
moderately inheritable condition. Reputable breeders will have
breeding pairs OFA (Orthopedic Foundation for Animals) certified prior
to breeding. OFA certification can be given only after a dog is over
24 months old. Responsible breeding by Keeshond breeders has led to a
tremendous decrease in the incidence of hip dysplasia in the breed.
