The Labrador retriever, known as one of the greediest breeds of dog, is hard-wired to overeat, research suggests.
The dog is more likely to become obese than other breeds partly because of its genes, scientists at Cambridge University say.
The gene affected is thought to be important in controlling how the brain recognises hunger and the feeling of being full after eating.
The research could help in the understanding of human obesity.
"About a quarter of pet Labradors carry this gene [difference]," lead researcher Dr Eleanor Raffan told the BBC.
"Although obesity is the consequence of eating more than you need and more than you burn off in exercise, actually there's some real hard-wired biology behind our drive to eat," she added.
