Hereditary Disease in Pedigree Dogs: When Breeding Causes Suffering

Selective breeding for exaggerated physical traits has saddled many pedigree dog breeds with inherited conditions that cause lifelong suffering. Reform of breeding practices is one of the most impactful areas of companion animal welfare.

Key Facts

Hip dysplasia affects up to 70% of some large breeds including German Shepherds and Labradors; progressive joint pain severely reduces quality of life
Syringomyelia — a condition where the skull is too small for the brain — affects a high proportion of Cavalier King Charles Spaniels and causes chronic pain and neurological symptoms
Brachycephalic breeds including Bulldogs, Pugs and French Bulldogs experience chronic breathing difficulties, dental overcrowding and exercise intolerance
Progressive Retinal Atrophy is an inherited blindness affecting dozens of breeds; DNA tests can identify carriers before breeding
Many hereditary conditions are entirely preventable through health-screened breeding; breed clubs and kennel clubs bear significant responsibility for breed health standards

Welfare Considerations

The scale of inherited disease in pedigree dogs represents one of the most significant unaddressed welfare crises in companion animal care. Millions of dogs suffer chronic pain, breathing difficulties, progressive blindness or neurological disorders as a direct result of human breeding decisions. Health testing before breeding, rejecting extreme physical traits, and purchasing from health-screened breeders are the most direct ways individuals can reduce this suffering. The popularity of brachycephalic breeds continues to grow despite high-profile welfare concerns, meaning public education is urgently needed.

What You Can Do

Never purchase brachycephalic breeds with severely flattened faces — choose healthier conformations within the breed
Ask breeders for evidence of health screening for breed-specific conditions before purchasing a puppy
Support campaigns for mandatory health testing and breeding restrictions for dogs with heritable conditions
Choose cross-bred or rescue dogs, which typically have greater genetic diversity and lower rates of heritable disease
Advocate for kennel club breed standards that prioritise health over extreme physical characteristics
