Looks like my sister's dog, except her's is light buff color. Dachshunds are funny little dogs. They have their human and that's about it. Not particularly friendly to anyone else. They think they are the king of the world. Large and in charge. She brings the dog to my house, it comes in and starts barking at me. Like "WTF are you doing here? Don't you realize my human is coming this way? You better watch yourself, buddy. I don't like the looks of you one bit."
