Emergency & dosing tools
The answers you need fast — with the thresholds vets actually use.
Dog Chocolate Toxicity Calculator
Weight + chocolate type + amount → exact methylxanthine dose and what to do next.
Benadryl Dosage for Dogs
The vet-standard 1 mg/lb dose in mg and tablets — with the safety checks charts skip.
Dog calculators
From breeding dates to adult size.
Dog Pregnancy Calculator
Due date plus a dated milestone calendar: relaxin test, ultrasound, X-ray, whelping prep.
Puppy Weight Calculator
Breed-size growth curves predict adult weight — with the full growth chart, not one number.
Cat calculators
Month-precision aging, not the 7-year myth.
Why these calculators are different
Personalised, not generic
Every tool takes your pet's actual numbers — weight, age, type, amount — and computes a result for your case, not a lookup row in a chart.
Referenced formulas
Thresholds and doses come from published veterinary references — Merck Veterinary Manual, AAHA/AAFP life-stage guidelines — and every page cites its sources.
Honest uncertainty
Estimates come with ranges and the reasons they can be wrong. A tool that pretends to certainty it doesn't have is a chart with extra steps.
Free, fast, no signup
Every calculator loads in under a second, works on your phone, and asks for nothing.
The $2,000 vet bill is the real emergency
Accident + illness insurance averages $62/mo for dogs and $32/mo for cats in 2026 — and it only works if you buy it before something becomes "pre-existing". See real prices by provider.
