“The finding that domestic dogs will naturally seek a dietary intake that is high in fat and that they will readily overeat if given the opportunity probably reflects the feeding behaviour of their wild ancestors,” said lead study author, Adrian Hewson-Hughes from the WALTHAM® Centre for Pet Nutrition. “In the wild, dogs and wolves often have irregular access to food and competition is fierce – leading them to try and maximise their calorie intake whenever possible.”
“However, domestic dogs today have regular access to food and many lead relatively inactive lifestyles compared with their wild ancestors,” added Dr. Hewson-Hughes. “By demonstrating that dogs will overeat when offered excess food, this research also reinforces the importance of responsible feeding measures, such as portion control, for helping ensure dogs maintain a healthy body weight.”
The research involved adult dogs representing five diverse breeds: the papillon, miniature schnauzer, cocker spaniel, Labrador retriever and St. Bernard. In a series of dietary studies, the dogs were offered combinations of wet or dry foods with varying levels of protein, fat and carbohydrate. The dietary nutrient balance selected by the different breeds was then assessed and compared.
The results showed that, when given the choice, dogs consistently regulated their intake of protein, fat and carbohydrate. Specifically, the dogs targeted approximately 63% of their daily calories from fat, 30% from protein and 7% from carbohydrate.
The research was conducted by the WALTHAM® Centre for Pet Nutrition – the science centre underpinning Mars Petcare brands such as PEDIGREE®, NUTRO® and ROYAL CANIN. It was undertaken in collaboration with scientists from the University of Sydney (Australia) and the Institute of Natural Sciences at Massey University (New Zealand).
WALTHAM® is committed to improving the health and wellbeing of companion animals. This research forms part of a wider programme of ongoing collaborative research into the impact of health and nutrition on body weight in dogs and cats.
The research has been published in Behavioral Ecology and is available for free online
