Would your vet be willing to try him on steroids instead of bromo? It can be harsh on the tum at times, and he's not responding really well to it.
I could ask, I'm just not sure since he seems to be in a lot of pain usually. (The owie stretches). He's only been acting normal-ish with a higher amount of Advil that was suggested to me to keep him comfortable until he had to cross the bridge. We have an appointment to have him Pts this Thursday so I could ask about it and see if he thinks it would help.
