My dog has watery diarrhea. Can I give him TUMS for his upset stomach?

Pet's info: Dog | Mixed Breed Large (61lb +) | Male | neutered | 7 years and 11 months old | 70 lbs

My dog is having to go to the bathroom about every 2 hours due to an upset stomach. He has very watery diarrhea. Is it ok to give him TUMS for some relief? I hate seeing him like this.

Tums is not likely to help with the diarrhea. His problem is not the stomach, it is the colon (large intestines). I suggest you use Pepto Bismol instead but please refer to these guidelines: ( https://www.petcoach.co/canigive/dog/pepto-bismol/ )\ A 70 pound dog would need 7ml - a teaspoon is 5ml - so I would give 1.5 teaspoons. If the diarrhea persists for more than 24 hours (despite the Pepto) then you need to get him to a vet for an exam. Also, if is not eating or feeling otherwise unwell he should see a vet.
