I've been hunting South Dakota sharptails and pheasants with EP's for the past fifteen years. Currently on my fourth one. All have been pretty solid trackers and retrievers - all scored fours in every retrieving portion of the NA tests they were in. Had a VC and two UT Pz 2's. One of the four I picked up as a year-and-half old, and he wasn't quite as enthusiastic about retrieving as the others, but came around after a season or two. (You can read about him in the latest issue of PDJ...) My newest pup is two and crazy about retrieving on land or in water. Absolutely relentless, won't give up until the bird is found or I drag him away. He is double-bred Blackhawk with some of the best-known Elhew blood thrown in. His problem right now is outrunning his nose - he's the hardest worker of any dog I've run, floats effortlessly and covers an incredible amount of ground, but needs to learn to use his nose more than his feet. Probably runs a little bigger than I need for pheasants but works out great for sharpies. My VC was HTA and Rebel bred, and probably will go down as the best dog I'll ever own. Some will tell you that HTA blood brings concerns of cancer; mine died of it at just seven, so there may be something to that. My first three EP's, and the HTA dog in particular, learned to run to their hearts' content on the prairies after sharptails, but would stay in close in heavy pheasant cover. The new pup is getting familiarized with the "hunt close" command and I suspect he'll soon learn to dial things in when we are in rooster country.
I picked up some of my dogs from Ross Callaway, who told me that if I treated them like shorthairs they'd turn out fine, and that was the case. I cultivated the retrieve early and often in the three I had as young pups and they really responded to it. Lots of drag / tracking work for NAVHDA tests seemed to get them interested in that at well. They don't typically track nose-down, but usually opt to run downwind of the track with a high head, and the end result is the same.
I always got a kick out of showing up at NAVHDA tests with pointers, and hearing "I didn't know they could swim / retrieve / handle close. Lots of myths out there about the breed.
