German Shepherd Dog Health Conditions#

Elbow Dysplasia

seriousCommon
Typical onset:0.52 years

Developmental elbow abnormalities causing chronic forelimb lameness.

Prevention: OFA screening. Controlled growth. Avoid excessive exercise during development.

Symptoms: forelimb lameness, reluctance to play, stiffness

Hip Dysplasia

seriousVery Common
Typical onset:14 years

One of the breeds most affected — approximately 20% of GSDs have hip dysplasia per OFA data.

Prevention: OFA or PennHIP screening mandatory for breeding. Keep lean. Controlled growth. Joint supplements.

Symptoms: difficulty rising, bunny-hopping, reluctance to exercise, hind end lameness

Exocrine Pancreatic Insufficiency (EPI)

seriousModerate
Typical onset:15 years

Inability to produce digestive enzymes. GSDs have highest prevalence of any breed.

Prevention: Not preventable. Managed with pancreatic enzyme supplementation and B12 injections. Lifelong treatment.

Symptoms: chronic diarrhea, weight loss despite eating, increased appetite, poor coat quality, gas/flatulence

Gastric Dilatation-Volvulus (Bloat/GDV)

life_threateningCommon
Typical onset:310 years

Life-threatening stomach twisting. Deep-chested breeds like GSDs are at high risk.

Prevention: Feed 2-3 smaller meals. No exercise 1hr before/after eating. Prophylactic gastropexy recommended during any abdominal surgery.

Symptoms: distended abdomen, unproductive retching, restlessness, drooling, rapid breathing

Degenerative Myelopathy (DM)

life_threateningCommon
Typical onset:712 years

Progressive spinal cord disease similar to ALS in humans. Caused by SOD1 gene mutation. Eventually causes complete hind limb paralysis.

Prevention: DNA test available for SOD1 gene. No treatment exists. Physical therapy and mobility aids (wheelchair) can maintain quality of life.

Symptoms: hind leg weakness, knuckling of paws, difficulty walking, crossing of hind legs, progressive paralysis
