I have a 2 year old miniature pinscher and took him to the vet after he started experiencing painful stool and pain around his abdominal area and rectum. The vet did an x-ray and diagnosed him with colitis. He was prescribed an anti-fungal medication (metronidazole), prescription food (the royal canin gastrointestinal high energy kibble), and 1 packet of probioitc added to his kibble daily (Advita probioitc powder). The reviews online for this probiotic are amazing! I had my dog on Canidae Grain-Free Pure Sea Salmon dog food prior to this vet visit, the food is supposed to be very good - better than the blue buffalo wilderness he was on before. So after doing everything the vet said I noticed some relief in the next few days. Now my dog is having diarrhea on and off and intermittent painful stools again and I don't know what to blame it on. I really think I should just go back to his food and do the probiotic because honestly it sounds better than the over priced prescription dog food I bought. Any help would be so greatly appreciated! I am desperate for a solution!!
