Tums Or Rolaids For Dogs. Vets do not prescribe antacids because they tend to reduce the blood's phosphate levels which can be very critical and essential in keeping a dog alive. The active ingredient, calcium carbonate, reduces excessive stomach acid in.
The dose most commonly used in dogs as an antacid is 0.5 grams and up to 5 grams total dose orally every 4 hours as needed. If your dog ate tums, do not worry because these pills are not harmful to dogs unless ingested regularly or in big quantities. I have also read reports of people giving their dog rolaids.
