“How much should I feed my dog?” — it’s one of those questions that sounds simple until you actually try to answer it. Do you go by the scoop on the back of the bag? Your vet’s last note? Or the very persuasive guilty eyes your Labrador gives you every single morning, strongly suggesting the answer is definitely more?
And if you’re simultaneously trying to figure out how much to feed a cat per day on top of all that, welcome to a household most of us recognise instantly.
Here’s the thing — working out how many calories does my dog need, or your cat for that matter, is genuinely trickier than pet food packaging makes it look. Those bag guidelines are built on broad averages, not your specific animal’s weight, breed, age, or energy level. If you’re also exploring homemade dog food recipes vet approved, or getting serious about hitting the right protein requirements for dogs daily, a rough scoop estimate just isn’t going to give you what you need.
That’s exactly what this Pet Nutrition Calculator is here to fix. It works as your personal dog calorie calculator, a precise dog feeding calculator by weight, and a dedicated cat calorie calculator — all in one free tool. Whether you’re maintaining a healthy adult pet, using it as a dog weight loss calculator to track a diet plan, or hunting for the best dog food for weight loss that actually fits your dog’s daily targets — this calculator gives you real numbers based on veterinary science, not guesswork. Let’s get started.
Pet Nutrition Intelligence
Veterinary-grade dietary calculations tailored to your pet’s exact metabolic profile.
Whether you landed here asking “how much should I feed my dog”, trying to pin down how much to feed a cat per day, or deep in research mode about the protein requirements for dogs daily — the fact that you’re here at all already puts you ahead of most pet owners. That curiosity? It matters more than you know.
Because here’s the truth: how many calories does my dog need doesn’t have one universal answer. It shifts with age, activity level, health, season, and the specific food you’re serving. That’s why this Pet Nutrition Calculator exists — not to replace your vet, but to put accurate, personalised numbers in your hands every single time you need them.
If you’re on a weight management journey with your pup, revisit the dog weight loss calculator every few weeks as their body changes — small adjustments add up to big results. If home cooking is your thing, use the macro outputs here alongside homemade dog food recipes vet approved to make sure every bowl actually hits the daily nutritional targets your dog needs. And when you’re comparing brands or researching the best dog food for weight loss, run them through our dog calorie calculator and dog feeding calculator by weight to see exactly how each one measures up for your pet specifically — not for some average dog that may look nothing like yours.
For your cat, the cat calorie calculator section is right there too, because cats have completely different energy needs and deserve their own numbers — not a scaled-down version of the dog data.
Feed with confidence. Your pet is counting on you, and now you’ve got the science to back every single scoop.
