Carrying extra weight shortens a dog's life and strains their joints. Here's how to help your dog slim down safely.
Confirm the weight problem
Extra pounds strain the heart and joints and raise the risk of diabetes and arthritis, so weight loss is one of the kindest things you can do for a chubby dog. Check body condition: you should feel the ribs easily with a light touch and see a waist from above. If your dog fails that test, talk to your vet before starting a plan — they'll set a healthy target weight, rule out medical causes like hypothyroidism, and confirm a safe rate of loss.

Fix the food and portions
Overfeeding is usually the core issue. Measure meals with an actual measuring cup rather than eyeballing, and follow feeding-guide amounts for your dog's target weight, not their current one. Feed a complete, balanced diet — see our picks for the [best dog food for everyday nutrition on a budget](/guides/best-dog-food-for-everyday-nutrition-on-a-budget), such as [Purina ONE SmartBlend Chicken & Rice Dog Food](/products/purina-one-smartblend-chicken-rice-dog-food). Cut back on treats and table scraps, which add up fast, and account for every extra calorie in the daily total.
Move more and slow the bowl
Gradually increase exercise with more walks, play, and sniffari outings, building up slowly so a heavy dog doesn't overdo it. Fast eaters who gulp their food and beg for more do better with a slow feeder, and a [lick mat](/guides/best-lick-mats-for-dogs) stretches out a small, low-calorie treat into a satisfying activity. Swap high-calorie treats for green beans, carrots, or a portion of kibble measured from the daily ration so training rewards don't sabotage progress.
Track progress patiently
Healthy weight loss is slow — often just one to two percent of body weight per week. Weigh your dog regularly, keep a simple log, and adjust with your vet's guidance rather than crash-dieting, which is dangerous. Celebrate non-scale wins too: more energy, easier movement, better stamina. If the weight won't budge despite honest portion control and exercise, revisit your vet to reassess the plan or check for an underlying medical cause.

Frequently asked
- How do I know if my dog is overweight?
- You should be able to feel the ribs with a light touch and see a waist when looking down from above. If the ribs are hard to feel and the waist is gone, your dog is likely overweight — confirm with your vet, who can set a target weight.
- How fast should a dog lose weight?
- Slowly and steadily — typically one to two percent of body weight per week. Rapid weight loss is unsafe for dogs. Work with your vet to set a healthy pace, and use measured portions and increased exercise rather than crash dieting.
