About PetCalcHub
Free, science-backed pet calculators with AI-powered health insights — now with 5 emergency toxicity tools.
Our Mission
PetCalcHub was built with a simple belief: every pet parent deserves access to reliable, science-backed tools to make informed decisions about their pet's health — without paywalls, signups, or data collection.
We combine veterinary-standard formulas from trusted sources — including AAHA, AAFCO, NRC, and Merck Veterinary Manual — with AI-powered insights that personalize each result for your specific pet. The result is a tool that doesn't just give you a number; it helps you understand what that number means and what to do next.
Our Editorial Standards
We want to be transparent: PetCalcHub is not a veterinary practice and our team is not composed of licensed veterinarians. Instead, every formula on this site is compiled from peer-reviewed, published veterinary sources, and we cite the source for each calculator so you can verify it yourself. Our content follows Google's E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) principles by being transparent about who we are and where our numbers come from.
Evidence-Based, Sourced & Verifiable
Updated June 2026
Our editorial team researches and documents each formula against primary veterinary references — AAHA, AAFCO, NRC, the Merck Veterinary Manual, AAFP, AVMA, ASPCA Animal Poison Control Center, and Pet Poison Helpline. We do not invent thresholds or give medical diagnoses. For any health decision about your pet, please consult a licensed veterinarian. In an emergency, contact ASPCA Poison Control at (888) 426-4435 or Pet Poison Helpline at (855) 764-7661 immediately.
Emergency Tools — Our Biggest Priority
"Dog ate chocolate" is one of the highest-searched pet emergencies on the internet. We built 5 dedicated emergency toxicity calculators so pet parents can assess risk in seconds — not minutes — when every moment counts:
- Chocolate Toxicity — theobromine dose based on chocolate type & dog weight
- Grape & Raisin Toxicity — kidney failure risk assessment
- Xylitol Toxicity — hypoglycemia & liver failure risk from sugar-free products
- Onion & Garlic Toxicity — Heinz body anemia risk from Allium family foods
- Ibuprofen (Advil) Toxicity — GI ulcer, kidney, and CNS toxicity risk
Each emergency calculator includes ASPCA Poison Control and Pet Poison Helpline numbers, step-by-step action guidance, and AI-generated advice tailored to the calculated risk level.
Why We're Different
Science First
Every formula is documented and sourced from peer-reviewed veterinary research. No guesswork, no "old wives' tales."
AI-Enhanced
Our AI engine generates personalized care tips based on your pet's specific results — breed, age, weight, and life stage.
Privacy First
All calculations happen in your browser. We never collect, store, or share your pet's information. No accounts, no tracking.
