Exact, sourced calculations — not guesses. Every result comes from a published formula with the math shown. Used by pet owners and vets alike.

Xylitol (in sugar-free gum, candy, and baked goods) can cause dangerous low blood sugar and liver failure in dogs. Estimate the dose below — but because product concentrations vary, always confirm with a vet.
Fluid therapy rate calculator
Estimate a patient's fluid plan: maintenance plus dehydration deficit, the hourly rate, and the drip rate for your giving set. A planning aid — adjust for ongoing losses and cardiac/renal status.
Dog calorie calculator
Estimate your dog's daily calorie needs from resting energy (RER) and an activity factor (MER), and how many cups to feed based on your diet's energy density.
Cat calorie calculator
Estimate your cat's daily calorie needs from resting energy (RER) and a cat-specific activity factor, and how much to feed based on your food's energy density.
