Puppy farming — the mass commercial breeding of dogs in inadequate conditions — causes severe welfare harm to breeding dogs and produces puppies with lifelong health and behaviour problems.
Puppy farming causes welfare harm at two levels: the breeding bitches themselves, who may spend their entire productive lives in isolated, unstimulating kennels with minimal human interaction; and the puppies they produce, who suffer from inadequate socialisation, immune challenges, and the health consequences of poor husbandry in their first critical weeks. The welfare harm extends beyond the farm: poorly socialised puppies develop into fearful, anxious adult dogs that suffer chronic stress throughout their lives. Lucy's Law addressed one distribution pathway, but online direct sales allow puppy farms to continue operating by presenting themselves as home breeders.
