These guys are truly great dogs, our Dachshunds are 3 half sisters. They are very head strong and do as they please. How did potty training go? Having self serve dog doors was our salvation.
Not a Dachshund but my youngest dog was very head strong. It was great for us having a doggy door for potty training this guy but now he does this... He pulled his mat out of his crate and made himself comfortable while he spied on the next door neighbors.
