Quick answer: the “10% rule” is a general way to keep treats from crowding out a complete diet: aim for no more than about 10% of daily calories from treats, with roughly 90% coming from an appropriate complete food. It is a guide, not a personalised prescription.

What counts as a treat?
Count every extra source of food: packaged treats, dental chews, table scraps, food placed in toys and pieces used during training. Small pieces can add up, especially for a small dog or when several people offer rewards.
Most treats are labelled complementary rather than complete. That means they are intended to be fed alongside other food, not to supply the whole daily ration.
How to use the 10% guide
- Find the dog’s current daily calorie target or ask your veterinary practice to help estimate it.
- Keep no more than about one tenth of that total for treats.
- Check the treat’s energy information or ask the manufacturer when it is not shown.
- Measure the day’s allowance in advance so different family members do not double-feed.
- Monitor weight and body condition, then adjust the overall ration rather than relying on the calculation indefinitely.
For example, if an individual dog’s professionally assessed allowance were 500 kcal per day, the general 10% ceiling would be about 50 kcal from treats. This is an arithmetic illustration only—not a recommendation that 500 kcal is appropriate for your dog.
Make training rewards go further
- Use very small pieces rather than repeatedly giving full-size treats.
- Reserve part of the dog’s measured daily food for training, if that food is practical and motivating.
- Choose non-food rewards sometimes, such as play, attention or access to a favourite activity.
- Keep a household tally or one shared treat container for the day.
Check more than calories
A treat must also be suitable for the dog. Choose an appropriate size and supervise chews because pieces can be swallowed and may cause choking or injury. Avoid foods known to be toxic to dogs. Follow storage instructions and wash hands after handling treats made from raw animal material.
Dogs on veterinary therapeutic diets may need different or much stricter treat choices. Allergies, pancreatitis, diabetes, kidney disease, gastrointestinal disease and weight-management plans are examples where an apparently small extra may matter. Ask the treating veterinarian rather than improvising.
Watch body condition, not just the measuring cup
Feeding guides and calorie estimates are starting points. WSAVA’s nine-point body-condition system considers features such as how easily the ribs can be felt, whether a waist is visible from above and whether there is an abdominal tuck. Ask your veterinary practice to show you how to assess your own dog consistently.
When to get individual advice
Contact your veterinarian if your dog is gaining or losing weight unexpectedly, is a puppy, is pregnant or nursing, has a medical condition, eats a therapeutic diet, or develops vomiting, diarrhoea, pain or other concerning signs. The 10% guide cannot diagnose a problem or set an individual calorie requirement.
