Quick answer

Avocado is best avoided. The flesh contains persin and is high in fat — pancreatitis risk in sensitive dogs. The pit and skin are choking and blockage hazards. Never feed guacamole (onion, garlic, salt). Safer treats include carrots or plain chicken.

Key takeaways

Small amounts of plain avocado flesh are unlikely to harm most dogs, but avocado is not recommended. It contains persin and is high in fat — pancreatitis risk. Never feed the pit or skin.

Persin and fat content

Avocado contains persin, a fungicidal compound that can cause vomiting and diarrhoea in dogs. The flesh has lower persin levels than leaves and skin, but is still not recommended.

The bigger concern for most UK dogs is high fat content — avocado can trigger pancreatitis, especially in breeds prone to the condition.

Parts to avoid

Part	Risk
Pit (stone)	Choking and intestinal blockage — emergency
Skin	Higher persin; difficult to digest
Leaves	Most toxic — rarely accessed in homes
Guacamole	Onion, garlic, salt, lime — multiple toxins
