About DogTally

What DogTally is

DogTally is a set of free calculators for dog owners. We started with three: a puppy adult-weight predictor, a food portion calculator, and a dog age calculator. More tools are on the way. Each one takes your dog's actual breed, age, and weight and runs the numbers in your browser.

Why we built it

Search "how much should my puppy weigh" and you get a generic chart, usually a single line for "large breed" or "small breed" with no source attached. Dogs are not that simple. A 12-week-old Labrador and a 12-week-old Great Dane are on completely different growth curves, and a chart built for one is close to useless for the other. We wanted calculators that ask for your dog's breed and current numbers, then give you a real, sourced estimate instead of a rough guess.

Our sourcing promise

Every formula and data table behind these calculators is listed on the methodology page, with the published veterinary and breed-registry sources we drew from, including AKC breed standards, WALTHAM growth research, and WSAVA nutrition guidelines. We label every result as an estimate, because that's what it is. Individual dogs vary, and nothing on this site replaces a veterinarian. If your dog's weight, appetite, or health seems off, call your vet, not a website.

How the calculators work

The calculators run entirely as JavaScript in your browser. Your inputs, your dog's breed, age, and weight, are never sent to a server or stored anywhere. Close the tab and the data is gone. We use privacy-respecting aggregate analytics to see which pages get used, but that's separate from the calculators themselves and never touches what you type into them.

Who we are

DogTally is a small, independent site. We're not a veterinary clinic, a breed registry, or a big pet-brand marketing arm, just people who wanted better dog math on the internet and built it. We don't have user accounts or a newsletter yet. If we add either, we'll say so here.
