Dogs should not eat rhubarb because it contains oxalic acid and soluble oxalates, which are toxic to them. Rhubarb leaves are especially dangerous, containing higher amounts of these toxic substances that can cause vomiting, diarrhea, kidney failure, and other serious symptoms. The stalks have lower levels of oxalates and are generally less toxic, but still can cause gastrointestinal upset if consumed in significant quantities. If a dog eats rhubarb and shows symptoms such as excessive drooling, vomiting, lethargy, or difficulty breathing, a vet should be consulted immediately. The treatment usually involves supportive care like IV fluids and pain relief to protect kidneys and manage symptoms.

- Rhubarb stalks: Lower toxicity but can still cause upset; feeding not recommended.
- Symptoms of poisoning: Vomiting, diarrhea, lethargy, kidney issues.
