Genetic mutation causes constant hunger in Labradors and Golden Retrievers – study

Mike Wills interviews Dr. Eleanor Raffan, a lecturer in Systems Physiology at the University of Cambridge.

Recent research has unveiled a genetic mutation in Labrador breeds, which results in persistent hunger and decreased calorie burning.

Dr. Raffan, a leading scientist at the University of Cambridge, conducted a study that underscores the significance of genetics in shaping both food interest and metabolic rate in dogs, drawing parallels to humans.

This genetic mutation leads to increased hunger between meals, and reduces calorie burning by about 25% when these pets are resting.

The study, involving over 80 pet Labradors and Retrievers, revealed heightened motivation to access hidden treats during tests, indicating greater hunger among dogs carrying the mutation.

Raffan recommends that owners of dogs with this mutation, feed them frequent small meals and provide plenty of distractions and play to encourage exercise, to prevent constant preoccupation with hunger.

She also emphasises the importance of a balanced diet for this breed of furry companions, and reducing treats to ensure they receive proper nutrition.

"Certainly, dogs who get regular titbits, are prone to weight gain."

"Feeding a balanced diet is a really good idea, because that allows them to get the right vitamins and minerals."
