Long Haired Dachshund - Ever since we had pets, it has always been a dachshund. Their breed is so intelligent and a really loyal buddy. They are hound dogs, a hunter and are so curious. But from what I read, the long haired ones are on the more gentle side and the short haired are the agressive one. Each dogs that we had really had their own character and personalities. Dogs, dachshund.... they indeed are man's best friend.
