Avocado
Use CautionAvocado contains persin which can cause vomiting in dogs.
Toxicity Level
3/10Why It's Dangerous
The flesh is mildly toxic. The pit is a choking hazard and the skin is hard to digest.
The Science
Persin (fungicidal toxin)Avocados contain persin, a fungicidal toxin found in the leaves, bark, seed, and skin of the fruit. The flesh of a ripe avocado contains the lowest concentration and is generally considered mildly toxic to dogs. Persin is much more dangerous to birds, rabbits, and horses than to dogs. The bigger risk for dogs is the large pit (choking and intestinal obstruction) and the high fat content of the flesh, which can trigger pancreatitis in susceptible dogs.

Dosage & Thresholds
The flesh of a ripe avocado is unlikely to cause serious toxicity in dogs in small amounts. The main risks are: (1) the pit, which can cause choking or bowel obstruction, (2) the skin and leaves, which contain higher persin levels, and (3) the high fat content, which can trigger pancreatitis with repeated exposure. A few pieces of avocado flesh are generally tolerated, but it is best avoided.
