Weight loss in dogs should be gradual and veterinarian-guided, especially if your dog is very heavy or has other health conditions. Start with a weigh-in and body condition score at the clinic, then ask for a calorie target based on ideal weight rather than current weight. Switching abruptly to a random light food without measuring portions often fails; precision matters.

Measure every meal with a scale or standard cup mark, and separate daily food from treats. Many calories hide in table scraps, dental chews, and training rewards. Use low-calorie vegetables your vet approves, or kibble taken from the meal allowance, for treats. Ensure every household member follows the same plan.

Increase controlled exercise as appropriate for your dog’s joints and breed: more frequent walks, swimming if available, and sniff games that burn mental energy without harsh impact. Sudden intense running is risky for obese Dachshunds or brachycephalic dogs; build duration slowly.

Monthly weigh-ins track progress; aim for steady modest loss. If weight stalls despite compliance, your veterinarian may screen for thyroid disease, adjust food, or recommend a therapeutic weight-management diet. Patience and consistency protect metabolism and help keep the weight off long term.
