I just brought home a new puppy

I’m planning to breed

I’m researching breeds before adopting

→ Breed Selector Quiz (8 questions → top 5 breeds + 10 personalized names from your answers) and Size Visualizer (compare breeds at scale next to a person).

I’m planning a vacation

I want to track daily care

Why these tools exist

Dog ownership comes with a stream of recurring questions: how much should I feed her, when’s the next shot due, is he overweight, what’s a normal water intake. Most answers exist somewhere — buried in a 2,000-word vet article, behind a paywalled pet-app, or split across ten different tabs. We pull them into one place, all formulas open, all calculations transparent.

Every calculator uses published veterinary references — AAHA life-stage guidelines for age, RER × MER from WSAVA for nutrition, standard 63-day gestation for pregnancy, AAHA puppy vaccine schedule. We link the methodology on every tool page. Your vet remains the source of truth for medical decisions; these are starting points and tracking aids.

Frequently asked questions

Are the calculations accurate?

The math itself is exact — we publish all formulas on each tool page. Whether the result applies to YOUR dog depends on individual factors (genetics, neuter status, conditioning, breed-specific norms) that no online calculator can fully account for. Use these as a starting point, then adjust based on your dog’s response and your vet’s guidance.

Are the tools free?

Yes. No signup, no email, no paywalled features. iDogNames is supported by display ads outside the tool forms and Amazon affiliate links on detail pages — never inside the calculations.

Do I need to register results?

No — every tool encodes inputs in the URL so you can bookmark, share, or print results without saving. (Some interactive tools like the Body Condition Score and Vaccination Schedule are most useful when bookmarked for re-checking.)

What about cat tools?

Most of these calculators use canine formulas (RER, AAHA life stages, etc.). For cats, visit our sister site at iCatNames.com — feline-specific calculators are on the roadmap.

Can I suggest a tool?
