My first dog was a dachshund. It was abused before I got her. At first she was hella nervous and would try to bite me or anyone that got near her but after a bit she got comfortable and was hella smart. Her hair was falling off too and I used castor oil and all her hair grew back and a nice healthy coat. Probably the best dog I had. Had a pit mix, she destroyed everything... had a black lab puppy, fucker chewed through my fence and one day hopped over the fence and ran away.
