Whether it is bacterial overgrowth/ imbalance/even an allergy to bacteria ( which can occur) or a food intolerance or allergic reaction. Task one is to get his GI tract healthy again so that it will be less reactive. The GI tract is the largest immune organ and the lining is brimming with immune cells. IgA is an antibody that protects that lining from foreign proteins, bacteria, parasites, all of the things that are perceived to be a threat. When an immune response occurs there is often inflammation. That inflammation will create damage in the lining as cells die off and leave ulcerated patches (that bleed). So you can have bloody diarreah from various reactions that take place in the GI tract because many of them result in inflammation and therefore damage to the lining.
To make matters worse when the diarreah starts then the motilty (motion) of the GI tract is often increased and it moves very fast and water is not removed in the colon to form a stool. I think that this may be nature's way of washing out the bacteria, virus, etc but it can cause dehydration as well as lose of beneficial bacteria. So it's a double edged sword I suppose.
With my own dog, I find that a fast (allowed water only) for twelve hours if possible helps immensely.
It gives the GI tract a time to relax and heal without the burden of digestion. I then feed a non-reactive food (for my dog it could be lean pork and sweet potato) and I will feed a high quality probiotic and perhaps a live culture yogurt. I will give a couple doses of probiotics daily for the first two or three days and by then we are usually back on tract with nice firm blood free stool.
I do think though it can be a combination of things that are often immune mediated that cause these issues.
When one is sparked it can leave the door open for another unfortunately. If they are back to back it is longer and harder for the GI tract to recover versus a reaction that occurs six months later when the GI tract has healed already prior to it. Some people speak highly of slippery elm and L-glutamine to heal the tract but for my dog a fast, then a non-reactive food (something she's had already on her elimination diet) and probiotics helps very much. It all depends upon what works for your dog though.
The probiotics are quite helpful. There is a new product called FortiFlora for diarreah, enteritis and improving the immune system available from vets and it's just one form of probiotic but one that is commonly used for pets and livestock. I have never used it but I do use various human ones with several strains of probiotics, I get good results from a few types as well as live culture yogurt.
