Hip dysplasia is a degenerative joint disease caused by an abnormal formation of the hip joint. The hip is a ball-and-socket — the head of the femur (the ball) should sit snugly inside the acetabulum (the socket). When the fit isn't right, the joint becomes loose, the cartilage wears unevenly, and over time the dog develops arthritis, pain, and reduced mobility.
German Shepherds, like most large and giant breeds, are predisposed to it. But predisposition isn't destiny — most cases can be prevented through a combination of responsible breeding and sensible early-life management.
The genetic side
Hip dysplasia is hereditary. A puppy is born with the genetic blueprint for hip development already determined; what unfolds over the next 18 months is the expression of that blueprint.
This is why x-ray screening of breeding dogs matters so much. At Kaiser, every adult dog in our program has had their hips and elbows x-rayed and certified through the German SV scoring system (the equivalent of OFA in the U.S.). Before we plan a breeding, we go back generations on the sire's pedigree to confirm there are healthy hips and elbows running deep in the bloodline — not just on the parents. A single titled grandparent doesn't tell the whole story; a consistent record across three or four generations does.
What owners can control
The other half of the equation is environment, and that's where the new owner has real influence. Three things matter most in the first 18 months:
Nutrition
Large-breed puppies need a food formulated for slow, controlled growth. Standard adult food, or even regular puppy food, often has too much calcium and too many calories for a GSD puppy. The goal is steady growth, not maximum growth. Ask your vet for a large-breed puppy recommendation.
Exercise
Avoid high-impact, repetitive exercise on hard surfaces before the growth plates close — typically around 18 months for a German Shepherd. That means no jogging on pavement, no jumping out of vehicles, no climbing stairs repeatedly. Free play on grass is fine. Forced exercise on concrete is not.
Weight
An overweight puppy is putting unnecessary load on developing joints. If you can't easily feel your puppy's ribs through a thin layer of fat, talk to your vet about reducing intake.
Kaiser's commitment
Every Kaiser puppy comes with a written guarantee that covers crippling hip dysplasia through the first year — confirmed by x-rays from a licensed veterinarian or the Orthopedic Foundation for Animals. Replacement is at no additional cost. We can offer that guarantee because the screening and breeding choices we make on the front end keep incidence extremely low. Most Kaiser families will never need to think about it again after they bring their puppy home.
