So ever since we got harley 4 years ago we always thought he was part miniature pinscher along with his chihuahua as that is what it said his breed was. Well now since my sister got a trainer and she saw harley she believe's him to be jack russell mostly because of how his hair is so wiry and his docked tail. I have better pictures of him at my parents house that i won't be able to put up until sunday but i do have one where you can see his hair.
