I don't know if Rolaids and Tums have the same ingredients but i found this on a good vet site...hopefully you don't have to worry but maybe you should call an emergency vet just in case?
[Tums for calcium carbonate requirements
Question: I need to include calcium carbonate in my dogs homecooked diet, but have yet to find it
except in the form of Tums. I have read that Tums can be detrimental to pets.
Is this true?
Answer:To the best of my knowledge, there is no
problem with using unflavored Tums (tm) in dogs for calcium carbonate
requirements. One Tums tablet contains 0.5gm of calcium carbonate. It is also
possible to find calcium carbonate as the calcium ingredient in some human calcium
supplements. I don't know the names but you could probably pick them
out by reading the ingredients.]
