Dog Avocado Toxicity Calculator
Assess the risk when your dog eats avocado — flesh, skin, pit or leaves — based on dog weight and amount consumed.
What Is the Dog Avocado Toxicity Calculator?
Assess the risk when your dog eats avocado — flesh, skin, pit or leaves — based on dog weight and amount consumed.
Avocados contain persin, a toxin that affects dogs differently depending on which part they ate. The pit also poses a serious obstruction risk. Enter the details below to assess the risk level for your dog.
Every result is based on published veterinary research and breed-size-specific growth data — not generic averages. This tool is completely free, works instantly in your browser, and requires no account or sign-up.

How It Works
Persin is a fungicidal toxin present in all parts of the avocado plant — leaves contain the most, followed by the skin, then the pit and flesh. Dogs are moderately susceptible to persin; less so than birds or rabbits, but persin can still cause myocardial damage, respiratory distress, and gastrointestinal upset at sufficient doses.
The calculator assesses risk based on the part consumed (which determines persin concentration), the estimated amount, and the dog's body weight. Additionally, avocado flesh is approximately 15% fat by weight — sufficient to trigger acute pancreatitis in susceptible dogs regardless of persin toxicity. Risk ratings are based on ASPCA Animal Poison Control guidelines and published veterinary toxicology literature.
