Why
Avocado contains a substance called persin. Dogs are relatively resistant to it, but birds, rabbits and some other animals are not. If you keep a pet bird, never let it eat avocado.
The bigger problems for dogs are fat, which can cause stomach upset or pancreatitis, and the large pit, which can cause choking or a blockage in the intestines. The skin and leaves contain more persin than the flesh. Guacamole usually contains onion and garlic, which are toxic to dogs.
Risks to watch for
- Vomiting or diarrhea
- Choking, gagging or repeated retching if the pit was swallowed
- Loss of appetite, belly pain or straining, which can signal a blockage
- Hunched posture and vomiting after a fatty meal, possible signs of pancreatitis
How to share safely
- If you do share, offer only a small piece of plain flesh with no skin or pit.
- Never give guacamole or seasoned avocado dishes.
- Contact your vet if your dog swallows a pit or shows signs of a blockage.
How much?
Occasional small taste at most. Healthier low-fat treats are a better choice.
