Thanks for all the replies. After the first bleed Jake seemed to lose intrest in his food. Unheard of for my lab. So I started making his food to include plenty of rice. Not a lot of change in the stool, but he is definatly interested in his food again. (wish I would have been making his food long before this.)
Right after the first bleed, the vet did blood work, to include looking for tick diseases which all came back fine. He also mentioned that it would be highly unlikly we would see any fungal issues in the area that we live in. Tomorrow I am going to call the vet to schedule time to do the flush. I would have to go to the specialist for a scope. So, we will do one test at time. Thanks again, I will let you know how it goes.
