Selective Breeding and Welfare Problems in Companion Animals

Selective breeding for exaggerated physical traits has created severe welfare problems in popular dog and cat breeds, with animals suffering lifelong health conditions that are direct consequences of the appearance traits that make them commercially attractive.

Key Facts

Brachycephalic obstructive airway syndrome (BOAS) affects an estimated 50% of bulldogs, French bulldogs, and pugs in the UK
BOAS causes chronic breathing difficulty, sleep apnoea, overheating, and in severe cases requires surgical intervention to allow normal function
Scottish fold cats have a genetic mutation causing osteochondrodysplasia affecting all cartilage and bone, causing painful joint disease across the entire body
Cavalier King Charles Spaniels have a skull shape causing the brain to be too large for the skull in a majority of individuals, producing chronic pain and neurological problems
German Shepherd Dogs bred for extreme rear angulation suffer elevated rates of hip dysplasia and spinal problems
The Kennel Club and RSPCA have collaborated on breed standard modifications to reduce exaggerated traits, with limited uptake
The BVA and BSAVA have called for cessation of Scottish Fold breeding on welfare grounds

Welfare Considerations

Breed-related health problems represent some of the most systematic and preventable welfare failures in companion animal care. Animals born into breeds with extreme conformations cannot escape the health consequences of the traits that make them fashionable — a French bulldog will spend its life breathing with difficulty regardless of the quality of care it receives. This is fundamentally different from acquired welfare problems caused by owner neglect, because the suffering is built into the animal at the genetic level and persists throughout its life. Reform requires change at multiple levels: breed standards that eliminate extreme traits, veterinary advice that honestly communicates breed health problems, and consumer behaviour change away from breeds whose welfare is systematically compromised by their standard form.

What You Can Do

Avoid purchasing brachycephalic breeds, Scottish fold cats, or other animals with heritable conformational health problems
If you already own an affected animal, ensure access to veterinary care and monitor for signs of respiratory distress, pain, or neurological problems
Support Kennel Club and breed-specific health schemes that use health testing to reduce heritable disease prevalence
Advocate for advertising standards that prohibit the promotion of breeds with severe welfare-compromising conformations
