Calculators
Tools by category
Puppy & growth
Puppy weight predictor
Enter your puppy's breed, age, and current weight. You'll see the adult weight range to plan for, from crate size to food budget.
Predict adult weight →Dog pregnancy calculator
Get a due-date range from the 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. It shows what your puppy gets and when, and 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 →Food & daily care
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 →Water intake calculator
Published figures for how much a dog should drink disagree, so we show the full range for your dog's weight, plus the point where you should call the vet.
Check water needs →Fresh food cost calculator
What The Farmer's Dog, Ollie, and other fresh plans cost for your dog's calorie needs. Estimates come from published prices.
Compare costs →Costs, gear & age
Dog age calculator
The 7-year rule is wrong. See your dog's human-age equivalent based on size. Small dogs and giant breeds age very differently.

Compare true costs →Pet insurance math
Compare insuring your dog against saving the money yourself, using published premium and vet-cost data.
Run the math →Growth charts for 77 breeds
Breed pages pair adult-weight standards with feeding ranges and growth notes.
