Plain-English summary
A dog that ate grapes or raisins may suffer from kidney failure due to a toxic substance called tartaric acid. Currently, there are no specific antidotes for this type of poisoning, but researchers are exploring the use of calcium carbonate as a possible treatment. The idea is that calcium carbonate could help neutralize the tartaric acid in the dog's stomach, potentially reducing how much gets absorbed into the bloodstream. While this treatment hasn't been tested in dogs yet, similar methods have worked for other types of poisonings. It's important to talk to your veterinarian if your dog has ingested grapes or raisins.

Abstract
Grape and raisin ingestion causes acute renal failure in dogs, recently attributed to tartaric acid toxicity. Standard treatments lack specific antidotes, creating a need for novel therapeutic strategies. Calcium carbonate (CaCO3 could theoretically neutralize tartaric acid in the gastrointestinal tract by forming insoluble calcium tartrate, potentially reducing systemic absorption. Although not yet clinically validated, analogous approaches for oxalate and fluoride poisonings suggest feasibility. This Viewpoint presented chemical and physiological rationales, stoichiometric calculations, practical clinical applications, and safety considerations. We propose the cautious clinical exploration of oral calcium carbonate as an adjunctive treatment in canine tartaric acid toxicosis.
