Why use PetWise?
Pet owners search the same questions every day. How old is my dog really? Am I feeding too much? My dog just ate a chocolate bar, so do I need to go to the emergency vet? Most answers online are a single rule of thumb with no source. PetWise calculators use the formulas veterinarians use, show every step, and explain the result in plain English, so you can make a better decision and know when to call your vet.
Where to start
- Curious how old your dog is? The dog age calculator takes your dog's size into account, because a Great Dane ages much faster than a Chihuahua.
- Got a cat? The cat age calculator uses the chart from International Cat Care and tells you which life stage your cat is in.
- Not sure how much to feed? The dog food calculator works out daily calories from your dog's weight and activity, then turns them into cups or grams of your food.
- Dog got into chocolate? The chocolate toxicity calculator estimates the dose your dog ate and how serious it is. If in doubt, call your vet first.
- Expecting puppies? The dog pregnancy calculator gives a due date and a calendar of what happens each week.
A calculator is not a vet
Every pet is an individual. Breed, health problems and medication all change what's normal. Use these tools to understand your pet better and to prepare good questions, and always ask your veterinarian before changing your pet's diet or when you're worried about its health.
