I have just purchased a 8 week old miniature dachshund. I really am a researcher but for some insane reason didn't do the research on dachshunds. My daughter's riding coach has 4 and she also fosters dachshunds. My experience with them have been favorable and they are so sweet. I fell in love and decided to get one. My concern is all the bad stories on house breaking. Any good advice for a newbie and what to expect?
