Dachshund
Today, dachshunds have crooked legs, loose skin, and a barrel-like chest. Over time, breeders selected dogs so that those features would appear in puppies. That way, dachshunds could do a better job of burrowing into tight spaces. Another feature is a long tail. They’re moderately muscular, with a strong breast bone that is easily identifiable. Dachshund’s tail should digress harmoniously down their spine and not dragging the floor when at rest.https://dachshundbreedcouncil.wordpress.com/uk-breed-standard/
