This chapter explores research from Cambridge University on a genetic mutation in Labradors and flat-coated retrievers that contributes to overeating. Personal anecdotes illustrate the connection between genetic predisposition and pet obesity, highlighting a study on the POMC gene's influence on hunger and energy expenditure. The conversation emphasizes the significance of understanding these genetic factors to aid in managing obesity in dogs and drawing parallels to human obesity.
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.
