How it works

From profile to portion in under two minutes

Most feeding guides give every Labrador the same answer. Ours doesn't. We use your pet's exact breed, life stage, current weight, activity level, and health profile to calculate a daily portion using the same RER formula used in veterinary practice.

Breed-specific data

41 breed profiles covering known health predispositions, typical weight ranges, and nutritional flags. A Beagle's guide is genuinely different from a Whippet's.

Veterinary RER formula

We calculate from Resting Energy Requirement — RER = 70 × weight0.75 — then apply life stage and activity multipliers, exactly as used in vet practice.

Always worth revisiting

Needs change. Bookmark your pet's unique profile URL and return whenever their weight, activity, or health picture changes. No account. No data stored.

The science

Why back-of-pack feeding guides are wrong for your pet

Every bag of pet food carries a generic feeding table based on weight alone. It doesn't account for whether your dog is neutered, whether your cat is geriatric (and therefore needs more calories, not fewer), or whether your Labrador has the genetic mutation that makes their appetite regulation genuinely different.

The veterinary RER formula gives a baseline that accounts for metabolic body weight rather than raw kilograms. Combined with life-stage and activity multipliers, it produces a figure calibrated to your specific pet, not a demographic average.

Our independence

Not a retailer. Not a brand. Just a guide.

Every other pet feeding resource you'll find is owned by a retailer, funded by a pet food manufacturer, or built on a personal brand. We have none of those relationships influencing what we tell you.

When we recommend a product, it's because it fits the pet's profile — not because a brand paid us to be first. Where we earn a small commission through affiliate links, we say so plainly.
