Has anyone every seen a case of elephant skin. I have a female gsd, that was previously mistreated. I just got her yesterday. She is a 7 yr old lord granddaughter, with a great temperment but is very thin, the tips of her ears are bleeding because of deer flys, and she has no hair on the backs of her rear legs. The skin in these areas looks rough and is dark grey in color. I took her to the local vet to get her checked and he said it was elephant skin. I've never seen this and would like to correct it, the vet said he could remove the skin and it would clear up but i'm going to get a second opinion. I was wondering if any of you have ever seen anything like this?
