Sources & Methodology

Our database currently covers 65 items. Every entry is compiled from established veterinary toxicology references and assigned one of four danger levels for dogs:

Primary sources

• ASPCA Animal Poison Control Center — toxic/non-toxic plant and food lists, case guidance
• Merck Veterinary Manual — toxicology chapters and dose thresholds (e.g. chocolate methylxanthines)
• Pet Poison Helpline — poison profiles and emergency guidance
• FDA — recalls and warnings (e.g. xylitol, bones)

How the chocolate calculator works

The calculator multiplies the amount eaten by the methylxanthine concentration of the chocolate type (from veterinary references), divides by your dog's weight, and maps the resulting mg/kg dose to the standard veterinary risk bands (~20 mg/kg mild, ~40 moderate, ~60+ severe). Real products vary, so results are estimates designed to help you decide how urgently to call a professional.

Limitations — read this

• Individual dogs vary: age, health, breed sensitivities, and luck all matter.
• Ratings describe typical dogs; puppies, seniors, and dogs with health conditions deserve extra caution.
• This is an educational reference, not veterinary advice, and it never replaces calling a vet or hotline.
