A study on United Kingdom's pedigree dog populations over 30 years reveals a decline in domestic purebreds, rise of crossbreeds, and increase in imported pedigree dogs.
Despite overall dog numbers increasing, pedigree dog population in the UK decreased annually by 0.9%, indicating changing owner preferences towards crossbreeds and imported pedigrees.
Concerns arise over limited genetic diversity in purebred lines leading to inherited disorders, emphasizing the need for genetic variability and breed sustainability.
Labrador Retrievers, French Bulldogs, and Cocker Spaniels remain popular, but population trends differ, with Yorkshire Terriers declining and French Bulldogs increasing by 22.1%.
A substantial increase in imported pedigree dogs, primarily from Ireland, Russia, and Poland, suggests efforts to expand genetic diversity in the UK breeding pool.
Genetic constraints and inbreeding depression in pedigree dogs raise health and welfare concerns, compounded by low breeding participation rates and neutering practices.
Growing preference for crossbreeds like Cockapoos reflects a paradigm shift towards health-conscious ownership, urging a reevaluation of breeding and genetic management practices.
Researchers advocate for tailored breed management strategies and import regulations to promote genetic diversity while maintaining breed integrity.
The study highlights the importance of informed breeding practices, genetic diversity preservation, and societal influences on dog ownership trends.
The findings bear significance globally, emphasizing the need for balanced breeding approaches that blend tradition with modern genetic science for canine welfare.
