My name is Shadow!

Help!!! I must rehome my poor man Shadow. He just turned a year old. He is not meshing with our small dog and cat. I tried it for a year and was hoping that when he grew up, the others would grow to like him. In addition, the rest of the family is pushing him away because of what he has caused the other pets. He is a very dog friendly pup, but the small dog we have is apparently not. He loves playing at the dog park, off-roading (car rides), and loves bike rides (running on a leash). He is up to intermediate on his obedience training and eager to learn more and aim to please. He would make someone an amazing companion and guard dog but needs exercise daily. He picks up residency quickly and will let you know if someone new comes around. If you have more questions, reach out. Almost forgot, he is Giant Schnauzer mixed with Shepard and a little over 70# and currently in Maryland.
