###Yes, but... TUMS is an antacid medication commonly used in people to treat heartburn and provide calcium supplementation. Used **judiciously**, it may be helpful for dogs under certain circumstances. Many pet owners look for over the counter solutions to resolve nausea symptoms in their pets before going to the vet. Over the counter products such as Pepto Bismol, Pepcid AC, and TUMS can be used to a certain extent in dogs, depending on the problem at hand. If your dog is vomiting or having severe diarrhea, it is always recommended that you have your dog examined by a veterinarian. Dosed properly, TUMS can be safe for dogs and can indeed provide relief for an upset tummy. TUMS can be used as calcium supplementation in animals with low calcium, or as a phosphate binder in dogs with high blood levels of phosphorus. Due to the effect of binding to phosphorus, the blood levels of phosphorus should be to prevent low phosphorus levels from occurring. Overall, there are better options available than TUMS at managing nausea and an upset stomach in dogs. Many formulations of calcium carbonate include xylitol as a sweetener additive. **Xylitol is toxic** to dogs, can cause serious side effects, and should be avoided at all times. It is best to avoid the usage of these antacids unless directed to do so by a veterinarian. TUMS can be helpful for relieving an upset stomach, but there are better options for dogs that are safer with fewer potential side effects.
