It is large amounts of grapes that were found to cause kidney failure (I believe thats is what it was but not sure). Your little one probably would have been fine eating just one grape but I would have probably done the same not knowing what is too much for such little dogs. Better safe then sorry, and thanks for sharing your story, you taught me how to induce vomiting if needed and you have taught at least 1 person that grapes are dangerous for out little furbutts |
