Genetics and Food Behavior in Dogs
Labradors and flat-coated retrievers have a genetic mutation in the POMC gene that affects their eating behavior, making them more persistent in seeking food. Research conducted by the University of Cambridge found that dogs with this mutation were hungrier and burned fewer calories, leading to weight gain. The study highlights how genetic variations can influence dogs' food intake and energy expenditure, shedding light on the obesity crisis in pets.
