Avocado

NOT RECOMMENDED

Best avoided. The flesh is very fatty and the large stone is a serious choking and blockage risk.

What to do

Withhold further avocado and monitor. If your dog swallowed the stone, was given guacamole, or has ongoing vomiting or belly pain, contact your vet.

When to contact a vet: Contact a vet if the stone was swallowed, if guacamole containing onion or garlic was eaten, or if vomiting persists.

Symptoms to look for

  • vomiting
  • diarrhoea
  • abdominal pain
  • lethargy
  • retching or choking if the stone was swallowed

Why

Avocado contains persin, which is a significant problem for some animals such as birds and horses. Dogs are much less sensitive, and the main practical risks are the very high fat content, which can upset the stomach or contribute to pancreatitis, and the large stone, which can choke a dog or block the gut. Guacamole is a separate concern because it usually contains onion and garlic.

Substances of concern
persin, high fat content
Safer parts
A small amount of plain flesh is unlikely to poison a dog.
Parts to avoid
The stone, skin, leaves and any guacamole containing onion or garlic.
Preparation
If avocado is ever given, only plain flesh in a very small amount, with the stone and skin removed.
How much matters
Small tastes of plain flesh are usually tolerated, but larger or repeated amounts raise the risk of stomach upset and pancreatitis.
Severity
Low to moderate
