Are uncured olives from a tree toxic to dogs?

Uncured olives from a tree can be toxic to dogs because they contain a compound called oleuropein. Oleuropein is a bitter phenolic glycoside that can cause gastrointestinal upset, including vomiting, diarrhea, and abdominal pain. In high doses, oleuropein can also damage red blood cells and cause seizures and kidney damage.

If your dog has eaten uncured olives from a tree, it is important to seek veterinary attention immediately. Treatment for oleuropein poisoning may include inducing vomiting, administering activated charcoal to absorb the oleuropein, and providing supportive care.

The amount of oleuropein in olives can vary depending on the variety of olive and the stage of ripeness. Green olives tend to contain more oleuropein than black olives. Ripe olives also contain less oleuropein than unripe olives.

If you are unsure whether olives are safe for your dog, it is best to err on the side of caution and avoid giving them to your dog. There are many other safe and healthy treats that you can give your dog instead of olives.
