Tools: Free Pet Calculators

ThePawManual's tools are free calculators that run entirely in your browser: no account, no email gate, just numbers you can trust matched to your dog or cat. Two are live today: the dog age calculator and the cat age calculator, both built on veterinary-informed aging models instead of the flat "multiply by 7" myth. Six more are in development and paired to guides you can already read in full.

Live now

Dog Age Calculator

Enter your dog's age and breed size to get their age in human years, using a size-aware model: small breeds age slower in their later years, giant breeds faster. Open the calculator →

Cat Age Calculator

Enter your cat's age for an instant human-year equivalent, based on the standard feline aging model (year one counts as 15, year two brings the total to 24, and every year after adds about 4). Open the calculator →

In development

We're building the rest of the toolkit deliberately, one working calculator at a time, rather than shipping placeholder tools. Here's what's next, paired with the guides that already cover the same ground by hand:

• Dog Food Calculator: until it ships, work the math yourself with how much should I feed my dog?
• Cat Food Calculator: see how much should I feed my cat? in the meantime
• Pet Cost Calculator: the full itemized numbers are already in how much does a pet cost?
• Dog Breed Selector: browse by lifestyle now in the dog breed guides
• Cat Breed Selector: browse by lifestyle now in the cat breed guides
• Pet Name Generator

No timeline promises here: each tool ships when it's actually built, matching how the two live calculators were done.

Frequently asked questions

What tools does ThePawManual offer?

Two free calculators are live: a dog age calculator and a cat age calculator, both converting your pet's age into human years using veterinary-informed models. Six more tools (covering food portions, pet costs, breed selection, and pet names) are in development.

Are the calculators free to use?

Yes. Every calculator on ThePawManual is free, runs in your browser, and doesn't require an account or email address.

How accurate are the calculators?

They're built on established aging models (a size-aware formula for dogs and the standard feline model for cats), not the outdated "multiply by 7" rule. They give a solid estimate, not a diagnosis; a veterinarian is still the right call for anything health-related.

What tools are coming next?

Food portion calculators for dogs and cats, a pet cost calculator, breed selectors for both species, and a pet name generator are all in development, in roughly that order.
