My brother’s red nose pitbull is sick. I have her because he is delpoyed overseas as a Marine.She has been sick since July. She has had surgery to correct irritable bowel symdrome. We have tried every medicine the vet has or has ever heard of. We have been to a couple different vets and they are all scratching their heads. She has had diarrhea since July 29. She has started to lose alot of weight and looks bad. Recently we tried to change her diet to only chicken and rice. It didnt work and was very hard on us. I have been trying to give her baby Immodium and it seems to be helping a little bit. The vet said that she may think my brother is dead and is greiving. I dont know what to do to help her. Im trying everything. Please help me and this “devil dog”.
