I always thought my Rott mix Emily, (lost her last year) would have been good at S&R. Sis and I were fixing the fence on the back line of the property one day (over a quarter of a mile away from the house), Emily climbed out of the yard and tracked me through heavy woods. She was my 'velcro' dog and couldn't stand to be left behind. I wasn't happy about her escaping (had visions of her getting hung on the fence) but I had to praise her for finding me.
The Samoyed Club in our area does a benefit event for their rescue group called the Canine Olympics. They invite all the different clubs out (agility, obedience, lure coursing, sledding, S&R, tracking, flyball, etc.) and put on a day for the general public to bring their dogs out and try all the different events. I've talked to the S&R people and even offered my property to them if they wanted to train (it's hilly and heavily wooded) but no one ever called. Oh well...
