Your dog, by the numbers

Generic charts treat a Chihuahua and a Great Dane the same. Our calculators start from your dog's breed, age, and weight, and every formula is cited on the methodology page.

Puppy weight predictor

Enter your puppy's breed, age, and current weight to see the adult weight range to plan for — crate size, food budget, and all.

Predict adult weight

Food portion calculator

Daily calories and cups per meal from the same energy formula veterinary nutritionists use, tuned to your dog's weight and activity.

Get portions

Dog age calculator

The 7-year rule is wrong. See your dog's real human-age equivalent based on size — small dogs and giant breeds age very differently.

Convert dog years

Dog pregnancy calculator

Due-date range from breeding or ovulation date, plus a week-by-week milestone timeline from veterinary references.

Estimate the due date

Puppy vaccine schedule

A dated vaccine timeline from the AAHA guidelines — what your puppy gets, when, and why your vet has the final say.

Build the schedule

Crate size chart

Match weight and length to manufacturer crate sizes, with the measure-and-add rule the makers publish.

Find the size

Water intake calculator

The honest range for your dog's weight — published figures disagree, so we show them all, with the vet-call threshold.

Check water needs

Why trust these numbers?

Every constant in our tools comes from published veterinary and breed-registry data, and we show our work. The methodology page lists each formula and links to its source. When a result is an estimate, we say so and show the range instead of pretending to precision.
