I have a 8 year old black lab. He has started losing his hair around his tail/rear area. I have put all sorts of store bought things to put on him and nothing seems to work. Have any of your dogs started losing hair and if so how did you correct this problem? I have had him to the vet as well and they just put the same thing on him as I do really. I looked at the ingredients of the two medications and they contained the same ingredients. I have been using Happy Jack skin balm. It seems to work the best. Any feedback would be appreciated.
