Genetic Diseases in Purebred Dogs

Selective breeding for exaggerated physical traits has created heritable disease and suffering in many popular purebred dog breeds.

Key Facts

Brachycephalic breeds like bulldogs and pugs have airways up to 50% blocked by their skull shape
Hip dysplasia affects approximately 70% of German Shepherds and many other large breeds
Cavalier King Charles Spaniels have a skull too small for their brain, causing chronic pain in most individuals
The Kennel Club has introduced health conditions into breed standards but enforcement is inconsistent
Rescue organizations report that welfare-compromised breeds are surrendered at higher rates

Welfare Considerations

The welfare crisis in brachycephalic and other health-compromised breeds is one of the most preventable in companion animal welfare. Unlike many welfare problems that require systemic agricultural change, genetic disease in dogs can be addressed through breed standard reform, veterinary health screening requirements, and consumer choice. The suffering of individual dogs born into breeds with inherent health problems begins at birth and continues throughout their shortened lives.

What You Can Do

Do not purchase brachycephalic breeds until significant health reforms are achieved
If you want a specific breed, require health test results for the breeding pair
Support breed standard reforms that prioritize health over appearance
Report breeders selling puppies with obvious health problems
Advocate for mandatory health testing requirements for breeding dogs
