Puppy farming causes severe welfare harm to breeding dogs and produces puppies with lifetime health and behavioural problems.
Puppy farming causes serious welfare harm across two populations: breeding dogs who spend their lives in inadequate conditions, and the puppies they produce who are separated early and develop lasting health and behavioural problems. Lucy Law has reduced but not eliminated the problem by closing the third-party pet shop route. Online direct sale and substandard licensed breeders remain significant sources of puppy farm welfare harm. Vigilance and education are the primary consumer-level defences.
