Your Dog Is Overweight. Let's Fix It Without the Guilt.

It's not just about overfeeding, though that's part of it. Several factors contribute:

Neutering changes metabolism. A neutered dog needs about 20 to 30 percent fewer calories than an intact one. Most owners aren't told this clearly enough at the time.

Breed predisposition is real. Labradors, Beagles, Cocker Spaniels, and Golden Retrievers are genetically inclined to gain weight. A study in Labradors identified a specific gene mutation (in the POMC gene) that affects appetite regulation. Some dogs are literally always hungry.

The packet guidelines are often too generous. Pet food manufacturers tend to overestimate because underfeeding leads to complaints while overfeeding leads to sales. The guidelines are a starting point, not gospel.

Treats aren't accounted for. A single dental chew can contain as many calories as 10 percent of a small dog's daily requirement. Add in training treats, chews, and the odd bit of toast, and you can easily add 30 percent to the daily intake without realising.

Forget the scales for a moment. The most useful assessment is body condition scoring, which is something you can do at home:

1. Ribs: You should be able to feel your dog's ribs easily with light pressure. If you have to push to find them, your dog is carrying too much fat.

2. Waist: Looking from above, there should be a visible narrowing behind the ribs (a waist). If the body is barrel-shaped with no waist, your dog is overweight.

3. Tummy tuck: From the side, the abdomen should tuck up from the chest. If it's level or hanging down, there's excess weight.

Your vet can give a more precise score (on a 1-9 scale), but these three checks give you a reliable indication at home.

Dramatic weight loss isn't the goal. Aim for 1 to 2 percent of body weight lost per week. For a 30kg dog, that's roughly 300 to 600 grams per week. Slow and steady prevents muscle loss and is more sustainable.

Your vet can calculate a target weight based on body condition scoring. Don't rely on breed averages because individual dogs vary enormously.

Food

Weigh everything. Stop using a measuring cup or eyeballing portions. A kitchen scale is the single most impactful purchase you can make. The difference between a slightly generous and a slightly modest portion adds up to kilograms over months.

Treats count. Whatever treats you give, reduce the main meal by the equivalent amount. Better yet, set aside a portion of the daily food allowance to use as treats throughout the day.

Consider a weight management diet. These are formulated to be lower in calories but still filling. They contain more fibre so your dog feels satisfied on fewer calories.

Exercise

Build up gradually, especially if your dog is significantly overweight or has joint issues. Extra weight puts extra strain on joints, so going from minimal exercise to long walks can cause injury.

Swimming is excellent if your dog enjoys it. It provides exercise with minimal joint impact. Start with 5 to 10 minutes and build up.

The goal is daily, consistent movement rather than occasional intense activity.

The Family Factor

Everyone in the household needs to be on board. One person sticking to the diet while another hands out cheese doesn't work. If visitors or extended family are the problem, have an honest conversation. Provide specific low-calorie treats they can give instead, so they still get the joy of giving without the calorie hit.

Owners often worry that their dog will be miserable on a diet. In my experience, dogs adjust within a week or two. The begging may actually increase before it decreases, but it does decrease once the new routine is established.

The results are worth it. Weight loss in overweight dogs leads to measurable improvements in mobility, energy, breathing, and overall demeanour. Many owners describe their dog as "acting younger" after losing weight.

If your dog also has arthritis, weight loss is the single most effective intervention available. More effective than any supplement, and comparable to medication in terms of improvement.

Your dog doesn't know they're on a diet. They'll adjust. And they'll feel better for it.
