There are a number of reasons this could be happening, and all should be diagnosed by your vet. Take the dog and a stool sample to the vet as soon as possible. Some causes include giardia, coccidia, irritable bowel sydndrome, a heavy (and potentially fatal) load of intestinal parasites, a partial GI blockage or other things. It is not good for it to continue so PLEASE seek medical help for your dog!
