My boxer Bono is 15 month. He have had blood in his stool for about six months now. I took him to three different vets, but they were unable to find anything. They kept running tests and giving him medicine without even knowing whats wrong. They sayd that by giving him medicine they are excluding all the posabilaties. It did not make much sence to me, so i stoped going to this vets. But the funny thing is that Bono do not act like a sick dog at all, nither his stool is soft. But all i know it should not be this way. If anyone had this problem, please help me to solve this "stool mistery".
