Calculators
Three sums that get done in the exam room and that you can do yourself. Everything is computed in your browser: what you type here goes nowhere.
Dog age calculator
The 2020 epigenetic formula, not "multiply by seven". Enter your dog’s age and see the human age it maps to.
Ideal weight calculator
From today’s weight and a 1-to-9 body condition score: what your pet should weigh, and how far off it is.
Calorie calculator
The RER × life-stage factor formula vets use, with weight in kilograms or pounds.
What you will not find here
There is no dosage calculator. Telling you how much medication to give your animal is practising veterinary medicine, and that is your vet’s job — they have seen the patient. There is no vaccine schedule yet either: it arrives when we have the full AAHA table in front of us, because a wrong vaccine date is not a weak page, it is harm.
