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 weightFood 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 portionsDog 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 yearsDog pregnancy calculator
Due-date range from breeding or ovulation date, plus a week-by-week milestone timeline from veterinary references.
Estimate the due datePuppy 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 scheduleCrate size chart
Match weight and length to manufacturer crate sizes, with the measure-and-add rule the makers publish.
Find the sizeWater 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 needsWhy 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.
