Your dog has grabbed avocado from the counter.
A swallowed pit needs prompt veterinary advice because it can cause obstruction.
The avocado pit, skin and flesh at a glance
| Compare | What to check |
|---|---|
| Pit | Choking and intestinal obstruction risk |
| Skin and leaves | Keep away from your dog |
| Ripe flesh | Only a tiny amount for a healthy dog |
- The pit is the biggest danger, because it can block the esophagus, stomach or intestines.
- Skin and leaves carry the highest persin content, so keep them away from your dog.
- Small amounts of ripe flesh are generally tolerated by most healthy dogs.
What happens if your dog swallows an avocado pit?
The pit sends more dogs to the emergency clinic than any other part of the avocado.
It's smooth, hard and round, and it's just the wrong size to pass through a dog's esophagus, stomach or intestines.
A blockage can look like this:
- Repeated vomiting, often right after eating or drinking
- Lethargy and hiding
- Refusing food
- A hard, bloated belly, or flinching when you touch it
- Straining to poop with nothing coming out
Don't wait to see if it passes.
What persin is
Avocados contain persin, a natural fungicidal toxin found in the leaves, skin and pit, with smaller amounts in the flesh.
It's extremely toxic to birds and horses.
Dogs handle it better, but large amounts can still cause vomiting and diarrhea, and in severe cases heart damage.
The skin and leaves carry the most persin.
A dog who chews on a houseplant or snags peels off the counter is at much higher risk than one who got a small bite of flesh.
If you're growing an avocado plant on a windowsill, move it somewhere your dog can't reach.
Toss peels and the pit right after you cut the fruit, and don't leave them in an open trash can.
Avocado is rich, and that matters
Rich, high-fat food can be unsuitable for dogs prone to pancreatitis.
Avocado is loaded with fat, so it can cause trouble even in a dog whose regular diet is perfectly fine.
Miniature Schnauzers, Yorkshire Terriers and Cocker Spaniels are especially prone.
If your dog has ever had a bout of pancreatitis, avocado is off the table for good.
Pancreatitis has several possible risk factors. A fatty meal cannot establish the diagnosis.
Think about that the next time someone's sharing chips and guac at a backyard party.
If you wanted it for their coat
A lot of people reach for avocado hoping for a shinier coat. These are safer and much easier to measure:
- Fish oil, which provides omega-3 fatty acids (EPA and DHA) that support skin and coat, with no persin.
- Flaxseed oil, a plant source of omega-3 fats.
- A little coconut oil works too, since most dogs handle its medium-chain triglycerides well, but keep the amount small.
Run any new fat source by your vet first, especially if your dog has had pancreatitis.

Frequently asked questions
Can dogs eat avocado pits?
No, a pit can lodge in the esophagus, stomach or intestines and cause a blockage.
Is avocado pit toxic to dogs?
The bigger worry is physical, because the pit can cause a blockage.
The skin and leaves also contain persin, a toxin.
Your vet can tell you what to do based on your dog's size and health.
Can dogs eat avocado skin?
Skip it. The skin has more persin than the flesh and can upset your dog's stomach.
Can dogs eat avocado flesh?
Most healthy dogs can handle a very small amount of ripe flesh, though the fat can still cause problems.
Dogs with a history of pancreatitis shouldn't have any.
