How Much Should a Dog Eat?

Start with the feeding guidance

There is no single portion that is correct for every dog. Use the food manufacturer's guidance as a starting point and consider the dog's age, size, activity, body condition and the food's energy density. Measure portions consistently so that changes can be assessed properly. If a dog receives treats, chews or other foods, include them when considering the total daily intake.

Adjust for life stage and circumstances

Puppies are growing and have different nutritional requirements from adult dogs. Pregnancy, nursing, unusually high activity and some health conditions can also alter feeding needs. A food labelled complete for the appropriate life stage is designed to supply the required nutrients when fed as directed. Fresh drinking water should always be available. Avoid making repeated food changes simply because the dog is hungry at one meal; look at the wider pattern of weight, body condition and behaviour.

Know when a vet should help

An unexplained change in appetite, repeated vomiting or diarrhoea, unusual thirst, persistent weight loss or gain, or difficulty maintaining a healthy body condition should not be managed solely by trial-and-error feeding. A veterinary professional can assess the individual dog and advise on an appropriate diet or portion. Keep a simple record of food amounts, treats, weight and relevant changes so that useful information is available when reviewing the routine.
