I have a Miniature Dachshund. He's a male short hair mini.... He's a great dog, but we are having a tough time house training him. We had some set backs in training due to illness in the family, and now he seems to prefer to #2 upstairs in the house, rather than outside.
I'm not a dog expert or anything, but of the few dogs we've had, he's absolutely been the smartest so far.
But I will admit, if I get the chance to get a English Bulldog - Stogie (the cigar shaped dachshund) would have a K9 sibling in a heart beat!
