Research indicates a significant genetic component to the eating behaviors of certain dog breeds, particularly Labradors and flat-coated retrievers. A notable mutation in the POMC gene, found in approximately 25% of Labradors and about 66% of flat-coated retrievers, is linked to increased food-seeking behavior, suggesting a genetic predisposition to overeating. This insight raises questions about the prevalence of this genetic variant among these breeds and its implications for pet obesity, a growing concern for veterinarians. The anecdote of a flat-coated retriever stealing food illustrates the potential for individual variation in behavior, yet reinforces the broader trend of greediness tied to genetic factors. Understanding these genetics can aid in addressing the obesity crisis in pets and promote healthier eating habits.
Labradors are known for being greedy dogs, and now scientists have come up with a theory about the genetic factors that may be behind their behaviour. In this episode from April 2024, the Guardian’s science correspondent and flat-coated retriever owner Nicola Davis visits the University of Cambridge to meet Dr Eleanor Raffan and Prof Giles Yeo to find out how understanding this pathway could help treat the obesity crisis in humans.
