Dogs are always hungry and one of its breeds Labrador Retriever is known for their increased appetite. But why are they so much obsessed with food?
A new study has reported that faulty genes contribute to hunger pangs and food cravings among these dogs. The lead author of the study, Dr. Eleanor Raffan, from the University of Cambridge said that Labrador topped the obesity lists in the UK and food motivation is one of the main reason behind the rise.
They analyzed the genome of 18 lean Labrador retrievers and pointed out the genes associated with obesity. Finally, they narrowed it down to one particular gene known as PMOC, which plays a crucial role in suppressing hunger when the body has energy reserves laid down as fat.
Dr. Raffan said, "We know POMC is important to humans and finding out more may lead to better treatment of human obesity."
