Frequently Asked Questions
Frequently Asked Questions
Is avocado flesh toxic to dogs and cats?
The flesh is only mildly irritating to dogs and cats, mostly causing stomach upset. The bigger concerns are the pit (a choking and blockage hazard) and the high fat, which can trigger pancreatitis in sensitive dogs.
What about guacamole?
Guacamole is riskier than plain avocado because it usually contains onion and garlic, which are toxic. Treat guacamole ingestion more seriously and call a vet.
Why is avocado listed as toxic if dogs and cats only get mild symptoms?
Avocado contains persin, which is highly toxic to birds, rabbits, and horses but only mildly affects dogs and cats. It is listed so owners know the stomach-upset and pit-blockage risks, and so bird owners do not assume it is safe.
