I agree with Lynn. If he has been on all sorts of ABx that will only add to the problem. I would start by adding some probiotics to his food to at least re-establish the healthy bacteria that is needed. How much food does she feed him, she could be overfeeding. Has she tried a grain-less food? It can take up to 12 weeks of being on a new food to see a difference. I would start with these things and see if they help. If 3 vets are seeing nothing then it may just be the dogs digestive system. What about Irritable Bowel? Sounds kinda like that. I googled it real quick and here is some info that popped up:
Dogs and cats are always eating things they shouldn't, which is why vomiting and diarrhea are so common in pets. But when they are getting sick for weeks or months instead of days, they could have a more serious digestive problem called inflammatory bowel disease.
Veterinarians aren't sure what causes inflammatory bowel disease, although they suspect it occurs when the immune system mistakenly attacks tissues in the digestive tract. Food allergies or problems with the pancreas may play a role in causing it. Even hair balls, which irritate the intestines, may be involved.
The convention therapy for inflammatory bowel disease is to give medications to stop the symptoms: steroids to suppress the immune system and sometimes antibiotics to control bacteria in the gut. Holistic veterinarians, on the other hand, believe it is possible to cure inflammatory bowel disease by strengthening the body's organs, especially the digestive and regulatory organs like the pancreas and live, and by helping the immune system work the way it is supposed to.
