Quick answer: Never feed this. Rhubarb leaves are seriously toxic, loaded with soluble oxalates that can damage kidneys and drop calcium levels. The stalks are safer but still not a dog food.

Rhubarb leaves are seriously toxic, loaded with soluble oxalates that can damage kidneys and drop calcium levels. The stalks are safer but still not a dog food.
The danger: oxalates in leaves damage kidneys.
Reactions vary with the dog’s size and how much they ate, and there is no safe home remedy — treatment for rhubarb poisoning is a job for a veterinarian.
What to Do If Your Dog Already Ate Rhubarb
Call your veterinarian or ASPCA Animal Poison Control at (888) 426-4435 immediately. Do not try to make your dog vomit unless a professional tells you to. If you can, note how much they ate and when it happened — that helps the vet decide on treatment.
