You can look in the paper and see if anyone is selling one, but since they're purebreds, it's pretty much going to cost you. Here is a link to a Dachshund rescue page. You could look into that. Keep in mind that this breed is NOT a solitary dog at all. They suffer from severe separation anxiety. My husband had one years ago. You cannot leave this breed home alone all day while you're at work.
