Obesity

Obesity is a condition in which too much fat builds up in a dog's body. The extra weight strains the joints, heart and breathing, raises the risk of diabetes and other diseases, and makes it harder for the dog to move and enjoy an active life. Weight creeps on gradually, so it is easy for an owner to miss, and a vet can help assess the dog's body condition.

What it is

Fat is not just stored weight. Fat tissue is active: it releases substances that keep a low level of inflammation going in the body and can make the body respond less well to insulin. Together with the extra load on the frame, this is why excess weight wears on the joints, makes the heart and lungs work harder and leaves a dog less able to cope with heat.

Weight builds up when a dog takes in more energy than it uses. Age, neutering, a less active life and some hormonal conditions can all tip that balance, and generous portions and titbits add up faster than they seem.

Everyday life changes too: walks get shorter, stairs and the car become harder, and play loses some of its fun. Getting to know how your dog's ribs, waist and belly should feel lets you notice early when weight starts to creep on.

Signs you may notice

When you stroke the dog's sides, the ribs are hard to feel under a layer of fat, and seen from above the dog no longer has a waist. The dog may tire sooner, breathe more heavily and be reluctant to move.

When to see a vet

Book a visit if you can no longer feel your dog's ribs easily, it has lost its waist, or it tires or pants much sooner than before. Weight gain with no change in habits is also worth checking.

For everyday care
