Sonic was adopted from our local animal shelter at 8 weeks and neutered there. We didn't know what breed he was (the shelter listed him as a "Labrador Retriever - mix" though we thought he was a brindle pitbull pup) and were just planning on getting him as a pet. He was incredibly high energy and active, to the point where we sought out a trainer. Our trainer pointed out that he looked like a Dutch Shepherd and his appearance and behaviors reflected that as he matured. Because he showed some potential for it, we began some protection training with him.
