One of their owners will probably flame me for saying this, but I think they are totally ugly. When the lady said she was going to get a dog, had no idea she would get that ugly thing. I was in her house a few days ago and the dog was all over me on the couch - he owned that place and paid no attention to the lady owner.
The lady doesn't have a strong personality at all and she would tell the dog to get down and he ignored her. If he had been my dog, I would have dragged him off the visitor and he would not have gotten up there again.
I think Dachsunds have exceptionally beautiful heads.
