Dogs can eat avocado flesh in small amounts, but it must be done with caution because avocado contains a fungicidal toxin called persin, which can be mildly toxic to dogs and cause vomiting, diarrhea, or intestinal blockage if consumed in large quantities. The flesh itself, which has the lowest concentration of persin, can be safe for most healthy dogs in moderation but is high in fat and calories, which could lead to digestive upset or weight gain. Other parts of the avocado, such as the skin, pit, and leaves, contain higher levels of persin and are toxic to dogs. Because of these risks, many vets and pet experts recommend avoiding feeding avocado to dogs, especially if the dog has special dietary needs or a history of pancreatitis. If a dog does consume avocado, it is important to monitor for any signs of illness and consult a veterinarian if symptoms occur.
In summary, small amounts of avocado flesh may be safe for dogs, but the risks associated with other parts of the fruit and the fat content make it generally safer to avoid feeding avocado to dogs altogether.
