Welcome to you. Your pup is so cute! I think I see wire-coated Jack Russel Terrier there for sure. He does have a lot of torso length, but those legs have more massive bones more like basset or corgy. Coloration sorta resembles corgy, too. Dachshund legs aren't that thick, IMHO, and I raised seven of the little weinie dogs myself over the years.
No matter what he is, he sure is a cute little guy!  |
