Well when I got home this morning, Noba was moving his tail more and more. He was able to raise it just above spine level, but it was still painful to wag back and forth. I called his vet (who is amazing dealing with Noba and his ongoing battle with HD)... the vet had heard of water tail before and said it was a possibility since the hose water for his bath was pretty cold. I took him in to the vet and they looked at his tail. Noba dog loves his vet, so when he came into the room, he began wagging his tail as much as he could, then he cried and started biting it. He was such a trooper when the vet looked at his tail, you could tell Noba was in a lot of pain, but he did great.... . The vet said it didn't appear to be broken or sprained, so he wrote it off pretty much as water tail (I brought the articles in that Wolf Q sent me the links too) and gave him some Rimadyl to take once a day... (he already takes it every other day for his HD). The vet called me on his way home to see how hound dog was doing and was amazed at the progress. We've been putting heat compresses on his tail all day (much to Noba's dismay... ) and he seems to be improving. He can lift his tail up about 60% of the way up to almost "hound dog status"... , so we'll see what the next few days brings. The vet told me to bring him back in within a week if no noticeable improvement. Thanks again Wolf Q and everyone for their prayers... I will try and post a picture of the "limp tail" hound as soon as I can!!!
