Despite being a healthy vegetable for humans, rhubarb is extremely toxic to dogs due to the presence of oxalic acid in its leaves and roots. Even small amounts of cooked or raw rhubarb can cause severe reactions in dogs, including drooling, labored breathing, and a swollen tongue. While most dogs dislike the sour taste, accidental consumption still requires immediate medical attention.
