My geohound loves to go caching with me. Unfortunately, unless the cache moves or it has food in it (which of course they never will) he doesnt help me find any. However, he helps in many other ways to help me find the caches. He gives people watching me enter and exit the bushes a sense of security that I am "just walking my dog and letting him do his business in the bushes" and not some predator lurking in the bushes. If there are mugglers nearby, I can use him as an excuse to wait and let them pass by as he sniffs around. And he is big enough to keep any potential "nasty-sorts" mugglers a safe distance away, letting me enjoy geocaching in safety! The only drawback I have had is trying to keep him on a leash when negotiating tough terrain. He is developing my balance though!
