Dogs can be given Tums to help treat an upset stomach. PetMD recommends administering unflavored Tums in liquid form, as the chemicals in the flavored Tums tablets are not good for dogs to consume.
Tums is a brand of antacid that is used to treat symptoms of heartburn, acid reflux and ulcers in humans. However, it is safe to give to dogs if they are experiencing symptoms of an upset stomach. Antacids work by increasing the pH of the digestive tract to a more basic level. The recommended dosage depends on the age and weight of the dog, so it is important to contact a veterinarian for guidance in determining the correct amount to administer.
