Hip Dysplasia

Hip Dysplasia

Hip dysplasia is a hereditary condition in dogs.  Affects females and males with equal frequency.  Can be controlled (to some extent) by environmental factors including diet.

The reported incidence of hip dysplasia is 1.7% with a much larger increase of occurrence in large and giant breeds.

More commonly seen in the
Chesapeake Bay Retriever, English Setter, German Shepherd, Golden Retriever, Labrador Retriever, Samoyed, and Saint Bernard Breeds.

There is an increased incidence of hip dysplasia in dogs spayed or castrated prior to 5 months of age.

A study found an increased incidence of hip dysplasia among dogs neutered at an early age, and the authors speculated that this increased incidence may have resulted from altered hip joint conformation secondary to increased bone length.
