Avocado praised for nutrition but poses risks for dogs

Avocados are rich in monounsaturated fats, vitamin E, potassium and folate, providing about 130 kcal per half fruit and supporting heart‑health by lowering LDL cholesterol. A single avocado, however, contains roughly 1 000 litre of water and is often shipped long distances from Mexico, Peru or Spain, limiting its environmental footprint.

While the flesh is generally safe for people in modest amounts, the fruit’s skin and pit contain persin, a compound toxic to dogs. In canines persin can trigger gastrointestinal upset, pancreatitis, and in severe cases heart‑muscle damage or breathing difficulties. Reported symptoms include vomiting, diarrhea, abdominal pain, lethargy, and loss of appetite. Large pieces of pit can also cause intestinal blockages. Pet owners are advised to keep avocado skins and pits away from dogs and to monitor any ingesting animal for signs of illness, seeking veterinary care if symptoms appear.
