Jack Terrier/Lab mix 6 yrs. 50 pounds I came into the shelter as a stray. I do love to go on leisurely walks and walk very nice on the leash. I do have a microchip, but it leads nowhere. I LOVE to play BALL!!! I would do best as an only dog. Did I mention I love to play ball?!!! If you love to play fetch, I'm your guy.
