A Groomer's Safety-First Guide Can dogs eat avocado? Best avoided. A York groomer explains the persin question, the serious stone hazard, and what to do if your dog eats some. [Lucy](https://www.fluffsyork.co.uk/dog-grooming-tips-and-tricks/author/lucy) Apr 22, 2026 --- The safety-first answer is that avocado is best avoided for dogs. There are two separate concerns: avocado contains a natural substance called persin, and the large stone is a genuine choking and blockage hazard. While a small amount of ripe flesh isn't the emergency that something like macadamia nuts or grapes would be, there's no good reason to take the risk when so many safer treats exist. My advice: keep avocado, guacamole and the stone well out of your dog's reach. Owners here at the salon in York often ask about this one, usually because avocado is everywhere in our own diets now. So here's the honest picture and what actually matters. ## The persin question Avocado contains [persin](https://en.wikipedia.org/wiki/Persin), a natural fungicidal compound found throughout the plant. It's most concentrated in the leaves, bark, skin and stone, and less so in the ripe flesh. Persin is well known to be harmful to some animals, and while dogs are more resistant to it than birds or livestock, it can still cause an upset stomach, vomiting or diarrhoea, particularly if a dog gets at the skin, leaves or stone rather than a scrap of flesh. Because the amount that causes trouble isn't clear-cut, the sensible approach is caution: don't offer it, and don't leave it where a dog can help themselves. ## The bigger hazard: the stone For most dogs, the part that worries me more than persin is the **stone**. It's large, hard and smooth, and it's exactly the sort of thing a dog will gulp. A swallowed avocado stone can cause a **choking emergency or an intestinal blockage**, and a blockage often needs surgery to resolve. The skin is tough and indigestible too. > **> Vet note:** If your dog swallows an avocado stone, or eats a large amount of avocado, skin or leaves, contact your vet straight away, or the Animal PoisonLine on 01202 509000 (a paid UK service). A blockage can turn serious quickly, so don't wait and see. ## Why the fat matters too Even setting persin and the stone aside, avocado flesh is **very high in fat**. A fatty treat like this can trigger an upset tummy, and in some dogs a bout of pancreatitis, which is painful and can be serious. That's another reason it's a poor everyday choice, even in the "safe" pet foods that use carefully processed avocado in tiny, controlled amounts. ## What to avoid completely - **The stone (pit):** a choking and blockage risk, the biggest single hazard. - **The skin and leaves:** tough, indigestible and higher in persin. - **Guacamole:** almost always contains onion and garlic, which are toxic to dogs, plus salt and sometimes lime. - **Large amounts of the flesh:** the fat load alone can cause problems. If your dog nabs a small piece of plain ripe flesh, don't panic, but do watch them and keep the rest away. It's the stone, the skin and guacamole that turn this from "probably fine in a scrap" into a real risk. ## What to do if your dog eats avocado - **Swallowed the stone:** treat it as urgent and call your vet now, watching for gagging, retching, drooling or a struggle to breathe or poo. - **Ate guacamole:** ring your vet, because of the onion and garlic content. - **Ate a lot of flesh, skin or leaves:** contact your vet for advice. - **Had a small scrap of ripe flesh:** usually not an emergency, but keep an eye out for vomiting or diarrhoea. ## Frequently asked questions **Is avocado poisonous to dogs?** Avocado contains persin, which can upset a dog's stomach, and dogs are more resistant to it than some animals but not immune. Combined with the stone hazard and the high fat, it's best avoided altogether. **My dog ate a bit of avocado, will they be OK?** A small piece of plain ripe flesh is unlikely to cause a serious problem, but watch for vomiting or diarrhoea. If they ate the stone, skin, leaves, guacamole or a large amount, contact your vet. **Why is the avocado stone dangerous?** It's large, hard and easily swallowed, and it can cause choking or an intestinal blockage that may need surgery. Always dispose of stones where your dog can't reach them. **Can dogs eat guacamole?** No. Guacamole usually contains onion and garlic, both toxic to dogs, along with salt and often lime, so keep it well away. ## This isn't veterinary advice We're professional dog groomers, not vets, so please treat this as friendly general guidance. If you're worried about your dog, or before acting on anything here, speak to your local vet. In an emergency, contact your vet or nearest out-of-hours clinic. --- *Fluffs is a professional dog grooming salon in Wigginton, York, offering one-to-one grooming for dogs of every breed and coat type across Haxby, Strensall, Huntington, New Earswick and the surrounding villages.
