Just a little update.
We ended up doing 4 doses of Strongid-T, 3-4 days between doses. The loose stool problem persisted, although not as bad..
So after speaking with my vet I decided to switch foods again. We went with Performatrin Ultra, Chicken and Brown rice. It worked and I saw improvement in his stool pretty much immediately.
Only thing is now his poop is a very dark brown, almost blackish on the outside. (I know gross sorry, I couldn't think of another way to describe it)It started with the food change, so I assumed it was from that. But now I'm wondering if it could be blood from the upper GI. Since I know that can cause dark colored poop. UGH So it looks like I'm going back to the vet with yet another stool sample. And crossing my fingers that is NOT blood.
If it's not one thing it's another. LOL Well at least the cow patty poops have stopped.
