Can Dogs Eat Rhubarb?
Short answer: No. Rhubarb leaves are toxic to pets because of soluble oxalates. The stalks contain very little and are listed as nontoxic, but there’s no reason to feed rhubarb.
Why it’s a problem
The Pet Poison Helpline says the leaves and greens contain soluble oxalate in dangerous concentrations, while the stalks used in jams and pies contain very little. Oxalate poisoning can cause stomach upset, weakness and trembling, a drop in blood calcium, and kidney injury.
How much and how to serve it
None. Keep rhubarb plants and leaves away from your dog. Rhubarb pie and jam are also high in sugar.
Risks to watch for
- Vomiting and drooling.
- Weakness and trembling.
- Low blood calcium.
- Kidney injury.
