I've been hunting these contests since the early nineties. Some small local contests and some big such as the worlds, won a quite a few, placed in a few and didn't do crap in a heck of a lot. Can 13 win in basically a 12 hr hunt? "Yes", but jmho, highly unlikely if your following every rule. I've seen many teams get "busted" by cheating. Such as pooling, having dogs stashed in certain places, other people hunting already and not part of the contest. Jump hunting with 4 man teams, road hunting, shooting over dead piles and the list goes on! I'm not saying that there are cheaters in every contest, but they are out there. Having private land is a huge advantage, using decoy dogs, "huge"! If the rules allow it, then so be it. I was in a recent hunt here in NV. Was in the same hunt last year in which 5 dogs won in a straight 26 hr hunt. Figured this year right around the same would win? Usually after going to the same contests year after year you get to know your fellow hunters. This year at the last minutes before check in, a team came in with 13...2nd was 5...3rd was 4. I call BS on that!!! I wasn't their to see how the dogs were being checked such as liver temp, green belly, jaw..etc. but??? Just kinda weird how it all worked out. Yes, we have a heck of a lot of dogs out here in the SW. But also a heck of a lot of yote hunters too. I guess there is only so much you can do to make sure that all yotes shot were in that contests time period? Guess when $$$ and or weapons are the winning prizes, people will do "anything" to win.
