This is a starting point, not a prescription. Breed standards are ranges and calorie formulas are estimates that a vet refines by watching the animal. Talk to your veterinarian before changing a diet, and especially before starting a weight-loss plan — sudden weight change can itself be a symptom worth investigating.

What the standard actually says

The AKC standard for the Cardigan Welsh Corgi gives an adult weight of 11.3 kg–17.2 kg and a height of 27–32 cm (11–13 in) at the shoulder. That spread is not sloppiness — it covers the difference between a small female and a large male of the same breed, and both are correct.

Calories follow weight, but not in a straight line. Energy need scales with bodyweight to the power of 0.75, not to the power of one. A dog at the top of this range needs 37% more food than one at the bottom, even though it weighs 52% more. That is why feeding by eye across two dogs of the same breed goes wrong so easily.

Neutering matters more than most owners expect. The same Cardigan Welsh Corgi needs about 924 kcal intact and 821 kcal neutered — roughly 11% less. Feeding the old amount after the operation is one of the commonest routes to a slowly overweight dog.

Frequently asked questions

How much should a Cardigan Welsh Corgi weigh?
The AKC breed standard puts an adult Cardigan Welsh Corgi between 11.3 kg and 17.2 kg — 25 lb to 38 lb. That is a range rather than a target: a dog at the bottom of it is not underweight and one at the top is not overweight. Frame, sex and body condition all move the right figure for an individual dog, which is why vets judge body condition score rather than the scales alone.
How many calories does a Cardigan Welsh Corgi need a day?
A neutered adult at the middle of the standard (14.3 kg) needs roughly 821 kcal a day — about 2.2 cups of typical dry food at 380 kcal per cup. An intact dog of the same size needs closer to 924, and a puppy under four months around 1,540.
How is the calorie figure worked out?
Resting Energy Requirement is 70 × bodyweight in kilograms to the power of 0.75, the standard allometric formula. That is then multiplied by a life-stage factor — 1.6 for a neutered adult, 1.8 intact, 3.0 for a puppy under four months. It is a starting point that a vet adjusts by watching how the dog responds, not a prescription.
How much should I feed a Cardigan Welsh Corgi to lose weight?
A weight-loss plan is fed to the target weight, not the current one — feeding maintenance calories for a body the dog already has is why diets stall. Select "weight loss" in the calculator and enter the target your vet agreed. Never start a weight-loss diet without that conversation: rapid loss is dangerous, and sudden weight change can itself be a symptom.
How long do Cardigan Welsh Corgis live?
The AKC gives a typical lifespan of 12–15 years for the Cardigan Welsh Corgi. Keeping a dog at a lean body condition through its life is one of the few things shown to extend it.

Breed standard: American Kennel Club breed standards. Energy formula: Merck Veterinary Manual, nutritional requirements of small animals.

Estimates for informational purposes only and not veterinary advice. Breed standards are ranges, not targets, and healthy weight varies with frame, age, neuter status and body condition score. Calorie formulas are a starting point that a vet adjusts by watching how the dog responds. Talk to your veterinarian before changing a diet, and especially before a weight-loss plan.
