Obesity risk for nation’s top dog breed

Britain’s most popular dogs can suffer from weight gain in middle age just like people, a canine health survey suggests.

Labrador Retrievers gain an average of 0.9kg each year between the ages of one and four, putting them at risk of being overweight by the time they reach middle age, the study shows.

Middle-aged dogs

Previous research suggests that, in the UK, Labrador Retrievers are the breed most likely to be overweight.

The dogs are fully grown after 18 months and are regarded as being near middle age by the time they reach four.

Researchers say putting on nearly 1kg every year after reaching maturity puts many at risk of obesity.

Nationwide project

The findings are part of the Dogslife project, which seeks to gain a greater insight into links between the Labradors’ lifestyles and their health and wellbeing.

Dog owners provided details of their animals’ lifestyle as part of the project, which is led by the University.

The team assessed the activity levels and size of more than 4000 Kennel Club registered Labrador Retrievers as they grew to the age of four.

Exercise habits

The study found that, on average, dogs were exercised for more than two hours each day.

Dogs that spent more time fetching, chasing and retrieving tended to weigh less.

Chocolate coloured Labradors were found to weigh, on average, 1.4kg more than yellow and black Labradors.

While exercise is important, other factors such as genetics appear to play a role in why some dogs gain more weight than others in early life.

Ground-breaking study

Initial findings from the Dogslife project will help researchers carry out further studies into the links between dogs’ body size, lifestyle and overall health.

The study, published in the journal Preventive Veterinary Medicine, was funded by the Kennel Club Charitable Trust, The Roslin Foundation and the Biotechnology and Biological Sciences Research Council.

Dogslife is a ground-breaking study of canine health, which is made possible thanks to the incredible dedication of dog owners.
