Humans and dogs share genes linked to obesity

A study from the University of Cambridge reveals that humans and Labrador retrievers share a gene variant, DENND1B, linked to obesity. Labradors with this variant have about eight percent more body fat than those without it. The research indicates that dogs with a high genetic risk for obesity show increased interest in food, similar to humans. The study also identified four other canine obesity genes that correspond with human genes. Owners can help mitigate obesity risks in dogs through regular exercise and diet control. The findings suggest that genetic predisposition plays a significant role in obesity for both species.
