Free pet tools
Quick calculators we use ourselves — for servings, age and daily water. Handy for any pet, whether or not you use FurHealth.
Dosage calculator
Choose a formula and enter your pet's weight to see the daily serving and roughly how long one jar will last.
- Uses the serving chart printed on our labels
- Works in pounds or kilograms
- Always start with half a serving for the first week
Pet age in human years
The old "multiply by seven" rule isn't very accurate. Dogs and cats mature quickly in their first two years, then age more slowly — and larger dogs age faster than small ones.
Daily water estimate
A common rule of thumb is about one fluid ounce of water per pound of body weight per day. Wet food counts toward that total, while heat, exercise and dry food increase it.
Sudden changes in drinking — much more or much less — are worth mentioning to your veterinarian.
These tools give general estimates for healthy adult pets and are not a substitute for advice from your veterinarian. See our Disclaimer.
