Let’s face it, dogs are rarely known for their self-restraint when it comes to food. From “just one more treat” eyes to those hopeful glances at your dinner plate, our four-legged companions know exactly how to work the room. But while a little indulgence now and then might seem harmless, carrying excess weight can have serious consequences for your dog’s health, happiness and lifespan.

Why Obesity in Dogs Is a Serious Concern

Obesity isn’t just about looks. A dog that’s overweight or obese is at risk of several long-term and potentially life-shortening conditions, including:

Diabetes

Cardiovascular disease

Arthritis and joint strain

Weakened immune function

Breathing difficulties

Reduced lifespan

Fat doesn’t just sit under the skin, it can infiltrate vital organs like the liver or “coat” others, making them work harder than they should. That’s why helping your dog maintain a healthy weight is one of the best things you can do for their long-term wellbeing.

Is My Dog Overweight?

A good rule of thumb (or paw) is to gently feel your dog’s ribs. You should be able to feel them easily without pressing hard, but they shouldn’t be poking out. If you can’t find them at all, there’s a good chance your dog is overweight.

Other tell-tale signs include:

A lack of waist definition

Sluggishness or breathlessness on walks

Reluctance to play

Begging or scavenging for food

Weight gain of 15–20% over their ideal body weight

If you’re unsure, try using the Body Condition Score (BCS), a simple 9-point scale used by vets to assess your dog’s body shape and fat coverage. A healthy dog should typically score around 4 or 5 out of 9, with visible waist definition and easily felt ribs without excess fat.

Checking your dog’s BCS regularly at home can help you catch any changes early, before they become a health concern.

The Risks of Carrying Extra Weight

Obesity in dogs doesn’t happen overnight, but the effects can last a lifetime. Just like in humans, carrying extra weight:

Puts stress on joints and bones, leading to osteoarthritis

Increases the workload on the heart and lungs

Can cause insulin resistance, raising the risk of diabetes

Reduces the motivation to exercise, creating a vicious cycle

Weakens the immune system, making your dog more prone to illness

Not to mention, dogs with obesity are more likely to be lethargic, less playful, and less engaged with the world around them. That’s not the life any dog deserves.

1. Start with a vet visit

Always begin with your vet. They’ll assess your dog’s current condition, determine how much weight needs to be lost, and recommend a safe, effective plan tailored to their breed, age and health status.

2. Feed smart, not less

Simply reducing your dog’s normal food isn’t enough,  in fact, it can be dangerous. Dogs need the right balance of nutrients to stay healthy, even while shedding weight.
