Then we started him on IV's and GI protectants. Then on Monday he was paralyzed in the rear legs. I did not know how this could happen and that has nothing to do with the GI track.He could not get up and this is a death sentence for a 160pound dog. so I had to start him on IV steroids and he did respond. But steroids would aggrevate the GI ulcers. Such a dilemma. I was so worried.
