Avocado is extremely toxic to dogs due to persin, a fungicidal compound present throughout the fruit. Persin is found in the flesh, skin, pit, and leaves, making every part dangerous. Even small amounts can cause vomiting, diarrhoea, abdominal pain, and potentially life-threatening heart damage. The high fat content also poses pancreatitis risks. Symptoms may appear within 12 to 24 hours. The large pit is a severe choking and obstruction hazard. Some dog foods and treats contain avocado oil, which may be safer in very small quantities, but whole avocados must be strictly avoided. Keep avocado plants and fruit away from dogs entirely.
Why Avocado Should Be Avoided
Contains persin. Causes vomiting, diarrhoea. Pit is choking hazard.
What To Do If Your Dog Eats Avocado

Watch out: Assuming guacamole is just avocado when it often contains onions and garlic. Offering "just a little" avocado flesh, underestimating toxicity. Not realising avocado plants are toxic too. Ignoring mild vomiting as unrelated to avocado exposure.
