Pet Toxicity and Treatment Calculator
Pet toxicity and treatment calculator estimates the educational threshold for common household hazards (onion, garlic, grapes) by dog body weight, plus the 3% hydrogen peroxide dose for vet-directed vomit induction. For 2026 use only as a discussion starting point with a veterinarian or pet poison helpline.

Formula
How it works: Thresholds are rounded teaching values from veterinary toxicology references. Sensitivity varies by individual dog, breed, and food preparation. Hydrogen peroxide is a treatment, not a toxin, used only when a veterinarian instructs.
Worked Example
Understanding household pet hazards
Many common foods and household items can harm dogs at surprisingly small amounts. Knowing the rough thresholds helps you triage and decide whether a vet call is needed.
- Onions and garlic damage red blood cells; effects can appear days after ingestion
- Grapes and raisins cause kidney damage in some dogs at very low doses, with no clear threshold
- Cooked, dried, and powdered forms of onion and garlic are often more concentrated than raw
- Hydrogen peroxide induces vomiting only within 1 to 2 hours of ingestion
- Never induce vomiting for caustic substances, sharp objects, petroleum products, or unconscious pets
When in doubt, call your veterinarian or the ASPCA Animal Poison Control Center. This calculator is educational only and does not replace professional veterinary judgment.

Frequently Asked Questions
Are these thresholds exact?
No. They are rounded teaching values from veterinary toxicology references. Individual dogs vary in sensitivity, and food preparation (cooked vs raw, powder vs whole) changes potency.
Why is grapes the lowest threshold?
Grapes and raisins cause acute kidney injury in dogs at unpredictably low doses. Some dogs show problems after eating a single raisin, while others tolerate larger amounts without harm.
When should I induce vomiting?
Only when a veterinarian or poison control specifically tells you to. Some poisons cause more damage when vomited back up, and some pets cannot safely vomit due to age or health.
What if my dog ate something not on this list?
Call the ASPCA Animal Poison Control Center (888-426-4435) or your local emergency veterinarian. Many other foods (xylitol, macadamia nuts, alcohol, caffeine) are also dangerous.
How long does it take for symptoms to appear?
Onion and garlic effects often take 1 to 3 days. Grape kidney damage can appear within 24 hours. Always seek advice promptly rather than waiting for symptoms.
Is garlic really toxic in small amounts?
A clove or two in a homemade dog treat is rarely a problem for medium dogs, but powdered garlic and garlic salt are more concentrated. Avoid giving garlic intentionally and seek advice if your dog eats a lot.
