    Yeah, why do such issues mostly arise on the weekends? I don’t get it. My two dogs have upset stomachs from time to time, one of them being much more inclined to do so more often. And in 8 out of 10 cases, it happens Friday night or Saturday. I can’t always pinpoint the culprit but I can rely on Pepto Bismol for dogs to take care of things (in most cases). In 10 years, I only needed to go to the vet (for this specific problem) 3-4 times.

    I hadn’t used Pepto Bismol for dogs until recently as I didn’t know it was ok for them. A friend recommended it and said it can do wonders in a pickle so I tried it the first chance I got. My little Daisy got an upset stomach which happens here and there and yes, of course it was a Friday night when it happened. I had Pepto Bismol and used it and it seemed to calm her. Next day everything was fine so it did work for her.
