Common questions
My dog ate olives straight off the tree — is that bad?
No real danger. Raw olives are extremely bitter, so most dogs stop quickly. Mild GI upset is the worst case.
Are jarred olives dangerous to dogs?
They are high in sodium and often contain garlic or seasonings. A few are usually fine, but salty or seasoned olives should not be shared.
