Rhubarb leaves are moderately poisonous to dogs. If you suspect poisoning, call your vet or pet poison control immediately. Generally speaking, the smaller the dog, the less needed to make the dog ill. Dogs with rhubarb poisoning may stagger and tremble. They may seem weak and have difficulty breathing. You may also notice increased urination and drinking along with diarrhea.
