Why
Persin in avocado is deadly to birds, rabbits and horses, but in dogs and cats it's mainly linked to vomiting and diarrhea. Evidence is thin, though, so it's unclear how much flesh is truly safe. The large, hard pit can lodge in the throat or intestines, and the high fat content can trigger pancreatitis. For these reasons we err on the side of caution and list it as dangerous.
How to give it / if eaten
If your pet swallowed a pit or ate a lot of skin or flesh, call your vet or an emergency clinic right away. Tell them when it happened, how much was eaten and whether the pit is missing. Don't induce vomiting at home without a vet's instruction.
Watch for these signs
Vomiting, diarrhea and poor appetite are most common. A stuck pit causes repeated vomiting, retching, belly pain and no stool; fat-related pancreatitis can show as severe belly pain and a hunched posture.
FAQ
My dog ate a little avocado flesh. Should I worry?
A small amount of flesh often causes no major problem, but that's not guaranteed. Watch for vomiting or diarrhea, and call your vet if your dog is small or ate a lot.
Some pet foods contain avocado. Is that a problem?
Some foods use processed avocado ingredients, and problems from those products are rarely reported. Still, we don't recommend feeding fresh avocado as a treat.
