Frequently asked questions
How old is my dog in human years?
It depends on your dog's size. The old “multiply by 7” rule is wrong: dogs age fast in their first two years and then slow down, and large breeds age faster than small ones. Use the Dog Age Calculator and pick your dog's breed size for a proper estimate.
How much food should I feed my dog or cat?
Daily food depends on weight, age, activity and the food's calorie density. Vets calculate it from the resting energy requirement (RER) — roughly 70 × body weight in kg to the power of 0.75 — multiplied by an activity factor. The Dog Food Calculator and Cat Food Calculator do that maths for you.
Are the results on PawCalc veterinary advice?
No. Every result is an estimate based on published veterinary formulas and breed data. It is general information to help you ask better questions — it never replaces your veterinarian, especially if your pet is ill or you are changing their diet.
How do I know if my dog or cat is overweight?
The best quick check is the body condition score: you should be able to feel the ribs under a thin fat layer and see a waist from above and the side. The Dog Ideal Weight Calculator and Cat Ideal Weight Calculator compare your pet's weight with the breed's ideal range.
