Obesity in dogs

Obesity is a common health problem in dogs that occurs when they carry too much body fat. Being overweight can affect your dog's quality of life and increase the risk of conditions such as joint problems, breathing difficulties and diabetes. Maintaining a healthy weight through the right diet and exercise can help support your dog's long-term health.

Dog insurance may help cover eligible costs for some health conditions linked to obesity, depending on your policy and your dog's circumstances.

What is obesity in dogs?

Obesity in dogs means they have an excessive amount of body fat that can negatively affect their health and wellbeing.

A dog’s ideal weight depends on factors such as their breed, size, age and body shape. Vets often use a Body Condition Score (BCS) to assess whether a dog is underweight, at an ideal weight, overweight or obese.

A healthy-weight dog should usually have ribs that can be felt without pressing firmly, a visible waist when viewed from above, and an abdominal tuck when viewed from the side.

What causes obesity in dogs?

Obesity usually develops when a dog consumes more calories than they use through activity and normal body functions. However, weight gain is influenced by more than just food and exercise.
Factors that can increase the risk of obesity include:

• Eating more calories than needed
• Too many treats or table scraps
• Not getting enough exercise
• Age-related changes in metabolism
• Breed and genetic factors
• Neutering
• Certain medical conditions

Some dogs may also gain weight because they have an increased appetite. This can sometimes be linked to medical conditions, so speak to your vet if your dog's hunger levels have changed.

Which dog breeds are more prone to obesity?

Any dog can become overweight, but some breeds appear to have a higher risk of obesity. Breeds that may be more prone include:

• Labrador Retriever
• Beagle
• Cocker Spaniel
• Dachshund
• Pug
• Cavalier King Charles Spaniel
• Scottish Terrier

A breed being more prone to weight gain doesn’t mean an individual dog will become obese. Diet, exercise and lifestyle all play an important role too.

Types and severity of obesity in dogs

Vets assess a dog's weight using a Body Condition Score (BCS). This 9-point scale looks at your dog's body shape and the amount of fat covering their body to determine whether they're underweight, at an ideal weight, overweight or obese.

Signs your dog may be overweight

The signs of obesity can vary depending on your dog's breed and body shape. Signs that your dog may be carrying excess weight include:

• Difficulty feeling their ribs
• Loss of a visible waist
• Reduced interest in exercise
• Becoming tired more quickly during walks
• Difficulty moving around
• Heavy breathing or panting after mild activity
• Difficulty grooming themselves
• Changes in body shape, including increased fat around the chest, back or tail base

Regular weighing and body condition checks can help you notice changes before they become a bigger problem.

What should you do if your dog shows signs of obesity?

Speak to your vet if you think your dog is overweight, especially if they’ve gained weight suddenly or are struggling with exercise. Your vet can assess your dog's body condition, check for any underlying health problems and help you create a safe weight-loss plan.

It’s important that weight loss is gradual. Rapid weight loss can be harmful and should only be done under veterinary guidance.

At what age are dogs more likely to develop obesity?

Dogs can become overweight at any age, but the risk often increases as they get older. Older dogs may become less active and have lower energy requirements, meaning they may need fewer calories than they did when they were younger.

Some dogs may also gain weight after neutering. This is because their energy needs may change and some dogs experience an increased appetite. However, weight gain can usually be managed with appropriate diet and exercise adjustments.

How can you manage obesity in dogs?

Managing obesity involves helping your dog use more energy than they consume while ensuring they still receive the nutrients they need. You can help your dog maintain a healthy weight by measuring food portions carefully, following your vet's advice on feeding amounts, limiting treats and avoiding frequent table scraps.

Gradually increasing exercise, weighing your dog regularly and using play or attention instead of food as a reward can also help. Some dogs may benefit from a veterinary weight-management diet, particularly if they need to lose a significant amount of weight.

Does pet insurance cover obesity?

Pet insurance doesn’t usually cover obesity itself, as weight management is generally considered part of routine care and prevention. However, some health conditions linked to obesity may be covered, depending on your policy and the circumstances of your claim. Always check your policy documents to understand what is and isn't included.

Obesity treatment options

Treatment depends on how overweight your dog is and whether any related health problems are present. Your vet may recommend things like a controlled weight-loss diet, adjusting portion sizes, a tailored exercise programme and regular weight checks. They may also investigate and treat any underlying medical conditions.

A successful weight-loss plan should be realistic and suitable for your dog's age, breed, lifestyle and health.

When to speak to a vet

Contact your vet if your dog is gaining weight unexpectedly, has become less active, struggles with exercise or you’re concerned about their body shape. You should also speak to your vet if your dog has a sudden increase in appetite, as this can sometimes be linked to an underlying medical condition.

Early support can help your dog reach and maintain a healthier weight, improving their comfort, mobility and overall quality of life.
