Duffy was "found as a stray" at 9 weeks old and turned over to the shelter I volunteer with. The manager of the shelter knew I was keeping an eye out for a prospective search and rescue (SAR) dog so she let me know when he had this puppy who needed a foster. That next week my SAR team hosted a seminar where I took him to socialize and see if he had what it takes to be a working dog. They all saw potential in him so I adopted him and we are currently training to certify in human remains detection.
Duffy has a lot of toy drive and will do most anything for it. He can be intense but he definitely has a sensitive side. I'm still trying to figure out the perfect training scenarios for him regarding duration, how amped up I should be getting him, and the hierarchy of toys in his view.
