Can dogs eat avocado?

Avocado safety for dogs is nuanced. The flesh of a ripe avocado contains only small amounts of persin, a fungicidal toxin, and is generally considered safe in small quantities. However, the skin, pit, and leaves contain higher concentrations of persin.

The biggest danger is actually the pit — it is large enough to cause choking or intestinal blockage if swallowed. The high fat content of avocado can also trigger pancreatitis in dogs prone to the condition, especially if consumed in large amounts.

Avocado is much more dangerous for birds, horses, and ruminants than for dogs. Small amounts of plain avocado flesh as an occasional treat are unlikely to cause problems for most dogs, but it should not be a regular part of their diet.
