A recent study conducted by the University of Cambridge has discovered that approximately 25% of Labradors are genetically predisposed to obesity due to a mutation in the POMC gene. This mutation affects hunger sensations and energy levels, leading to increased appetite and reduced calorie burning. Lead researcher Dr. Eleanor Raffan highlights the dual challenge faced by dogs with this mutation: they continuously seek food and exhibit a lower energy expenditure.

The research involved 87 adult Labradors undergoing various tests to evaluate their eating behaviors, energy metabolism, and the effects of the POMC gene mutation. Results indicated that affected dogs showed a marked increase in food-seeking behavior and a significant decrease in calories burned while resting. Despite consuming the same amount of food as dogs without the mutation, those with the genetic variant exhibited greater hunger and reduced calorie expenditure.

To manage this predisposition, owners are advised to employ strategies such as using puzzle feeders or spreading out meal times to slow down the dogs’ eating. Funded by The Dogs Trust and Wellcome, the study not only sheds light on the complexities of obesity in dogs but also underscores the importance of tailored approaches in maintaining a healthy weight for Labradors and flat-coated retrievers with the POMC mutation.

The insights from this research highlight the need for awareness and proactive management of diet and exercise routines for dogs at risk of obesity, due to genetic factors. This understanding is crucial in combating obesity and promoting healthy lifestyles among susceptible canine populations.
