Most overweight dogs can reach a healthy weight with a few consistent habits — no crash diets, no drama. The key is measuring what goes in, moving a bit more, and giving it time. Here's the approach vets actually recommend.
1. Measure every meal by weight
Scooping by eye is the single biggest cause of overfeeding — a casual "cup" is often 20–30% too much. Use a kitchen scale and feed to your dog's target weight, not its current weight. The bag's guidance is a starting point, not gospel; many dogs need less.
2. Get treats under control
Treats should be under 10% of daily calories. Swap biscuits for pieces of carrot, green bean or cucumber — most dogs happily accept them, and they're almost calorie-free. Count anything scavenged or shared from your plate.
3. Move a little more, gradually
Add walk time slowly, and use joint-friendly options like swimming if your dog is stiff or very overweight. Little and often beats one exhausting outing.
4. Weigh monthly and be patient
Safe weight loss is about 1–2% of body weight per week. Track it monthly so you can see progress and adjust. For a significantly overweight dog, or one with health issues, plan the diet with your vet — they can rule out causes like thyroid problems and recommend a prescription weight-management food if needed.

How fast can a dog safely lose weight?
About 1–2% of body weight per week. Faster than that risks muscle loss and other problems, so go slow and recheck monthly.
How much should I feed my dog to lose weight?
Feed to the target (goal) weight rather than current weight, measured by a kitchen scale. Your vet can calculate a precise calorie target for a significantly overweight dog.
What are good low-calorie dog treats?
Carrot, green bean, cucumber and small pieces of their own kibble work well. Keep all treats under 10% of daily calories.
My dog acts starving on a diet — what do I do?
Split meals into more, smaller portions, add low-calorie veg for bulk, and use a slow feeder. Persistent extreme hunger is worth a vet check.
