Pituitary dwarfism in German Shepherds causes severe growth and health abnormalities from a genetic mutation with high prevalence in the breed, resulting in significant suffering and shortened lifespan.
Dwarfism in German Shepherds causes a cascade of welfare problems from hormonal deficiency. The retained puppy coat fails to protect the skin adequately, leading to secondary bacterial infections and dermatitis causing chronic discomfort. Neurological abnormalities affect quality of life progressively. Hormonal imbalances affect multiple body systems simultaneously. Affected dogs often appear younger than their age due to their appearance but experience significant physical discomfort. The genetic nature of the condition and the availability of carrier testing makes continued production of affected puppies an avoidable welfare outcome.
