Dog Weight Management Guide

Assess body condition, not just the scales

Healthy weight is important for mobility and long-term welfare. A dog's ideal weight depends on its size, build and individual circumstances, so a number on a scale should be interpreted alongside body condition. Regular weighing and visual or hands-on checks can identify gradual changes before they become significant.

Review food, treats and activity

Weight gain can result when energy intake consistently exceeds energy use. Review meal portions, treats, leftovers and food used in training, and consider whether exercise is appropriate for the dog's age and health. PDSA recommends adapting exercise to the individual dog. Changes should be gradual, particularly if a dog is unfit or overweight.

Use veterinary support when needed

Do not put a dog on a rapid or restrictive diet without professional advice. Unexpected weight loss can also indicate illness. A vet can assess body condition, investigate medical causes and set a safe weight-management target. Puppies, pregnant dogs, older dogs and dogs with medical conditions need particularly individual plans. Successful management is usually a long-term routine rather than a short-term diet.

Questions to consider

Before acting on general advice, consider the individual dog's age, health, temperament, previous experience and daily routine. Check product instructions and current UK guidance where rules apply, and keep records of relevant veterinary or care decisions. If a problem is persistent, sudden or outside normal day-to-day care, use an appropriately qualified professional rather than relying on a generic guide.
