The scientists at the University of Cambridge Metabolic Research Laboratories are looking for a few good—and chubby—dogs!  Their GOdogs Project is conducting cutting-edge genetic research on why certain dog breeds tend to become overweight (Labrador Retrievers, we’re talking to you!).  They also hope that this research will shed light on the genetics of human obesity.

If you own a Labrador and live near the Cambridge University Veterinary School in the UK, your dog can become an important part of this ongoing study.  The researchers also welcome input from the owners of other types of dogs.  Owners of all dog breeds can answer a questionnaire about their dog’s eating habits, and if you have a Retriever, Pug, or Bulldog, the Project is looking for DNA samples from your pup.  Click HERE to learn more about participating in the study.

The GOdogs website has lots of great information about obesity in dogs.  Did you know that between 34 and 59% of dogs can be classified as overweight?  Obesity causes significant health problems in our pets, including:

• Joint disease
• Heart and lung problems
• Hormonal disorders
• Incontinence
• Cancer
• Shorter lifespan

Why are so many dogs overweight?  The Project points to the modern lifestyle of pampered pets as a prime cause.  Your dog’s body stores fat as an energy reserve to draw on in times when food is scarce.  Today’s dogs aren’t running around and hunting, so a sedentary lifestyle combined with lots of food that’s high in fat and calories can lead to obesity.

The fact that some dog breeds are prone to obesity suggests that genetics play a role in this, particularly when it comes to appetite and hunger.  Previous studies on obesity in humans and other animals have shown that certain genes affect a part of the brain that controls hunger called the hypothalamus.

What about the link between genetics and obesity in dogs?  The GOdogs Project has been collecting canine eating behavior and genetic data since 2013.  In 2016 they published their first findings about a genetic cause for obesity in Labradors.  One particular gene called POMC has been found to be associated with obesity in Labradors (and flatcoated retrievers).  A quarter of UK Labs have this gene and these dogs were found to be around 4 lbs. heavier than Labs without the gene.  POMC plays a role in regulating feelings of hunger and fullness.

Whether your dog has a genetic predisposition to being overweight or not, there are practical steps you can take to manage your dog’s weight.  Check out these strategies for monitoring your dog’s weight, regulating food intake, minimizing your dog’s feelings of hunger, and making sure your dog gets plenty of exercise, all courtesy of the folks at GOdogs.
