It is my understanding that avocados are not, per se, toxic. Itâs the persin which is toxic, and that is found in the skin and the stone. Persin is a fungicidal toxin. C23H40O4. Interestingly, for those who like this kind of information, not all varieties of avocado appear to be toxic to the same degree.
The flesh of an avocado is safe for your dog. However the pit, if eaten, may cause an intestinal obstruction. Avocados contain a substance called persin which some animals (cattle, horses, goats, rabbits, birds and fish) are very sensitive to. But dogs would have to eat very large amounts of avocados to get sick.
