Well, with our problem with Bava, the vet gave him something to calm down his colon. He gave him a shot and prescribed some pills. Mike (Our vet) said that sometimes their colon gets excited (not sure how he put it really, but something like that) and the only way to get it from being 'excited/irritated' is via drugs. After a week of blowouts we're back to normal the next morning, I'm gonna keep him on it for a couple of days.
I can look & see what it was he prescribed if you'd like to know.
I also asked about changing our food, and he said that we for sure didnt' want to swap over cold-turkey, even if it were the food causing the problem, to stay with it and gradually switch, or we could have some really bad problems.
