I could use some insight if anyone has ideas...Izaak has been having diarrhea intermittently since this last summer. It started after a trip to the lake. I thought it had to be Giardia, we didnt see any on a fecal (there was a lot of bad bacteria-Clostridium) but still treated with Metronidazole in case of Giardia and because of bacteria. It seemed to get better briefly but came back soon after. We have tried Metronidazole 3 seperate times in the course of this happening. Sometimes it gets better, other times it does not. I had even dewormed him even though we weren't seeing parasites. He also has hair loss along his legs occasionally. Nothing on skin scrapings..treated with antibiotics (cephalexin) thinking it was allergies. He has been on TOTW but ordered a bag of Science Diet z/d in the thoughts that it is a food allergy...I have even tried a bland diet of low residue food. Sometimes there is blood present but not always. He has accidents in the house because he can't hold it. No vomiting, weight loss or other symptoms....Suggestions/thoughts/ideas?!?!
