Cost of owning a dog calculator
Add up the first-year, yearly and lifetime cost of a dog by size from assumptions you can see and change.

What it does
Choose a dog size and a starting level of low, typical or high, and the calculator fills in nine yearly costs and five first-year costs. You can change any figure. It then shows the first year, each year after that, the monthly cost and the total over the years you plan for.
How the numbers are worked out
The yearly figures are food, routine veterinary care, flea, tick and heartworm prevention, grooming, supplies, training, boarding or a sitter, optional insurance and licensing. The first-year figures are the adoption fee or purchase price, spay or neuter surgery, puppy vaccines and first exams, gear and puppy classes. The result is simply the yearly costs multiplied by the years, plus the one-time costs.
The starting figures are rough planning ranges in US dollars that we chose, not quotes and not survey averages. They give you a place to start, and you are expected to replace them with prices from your own area, vet and food. The default number of years is a typical lifespan for the size: 14 for small dogs, 12 for medium and 10 for large.
Where it stops being right
The calculator uses today's prices with no inflation, and it cannot predict an emergency. A single surgery or a long illness can cost more than all the yearly costs in a year. Breeds differ too: a coat that needs professional grooming, a breed prone to expensive conditions or a very large appetite can move the totals a lot.
Treat the result as a budgeting aid. A savings cushion or pet insurance is a way to prepare for what a calculator cannot, and your veterinarian can tell you what routine care your dog will need.
