I had a GSD and his nose was terrible with growth and being rough. OMG, I hate to admit this, but it was my fault. I didn't think and put down that "get rid of any pet odors plus smell good" junk onto my carpet. This happened soon after, so I pretty much guess I caused it. :mad: Took me a long time to forgive myself for it. I put vaseline on it, but it just never went away. He had it on his nose for five more years until he passed on. Vet said some dogs have it, allergies. Didn't bother him, it bothered me. Man, I miss him.
