Weimeraner would be ok, but you honestly wouldn't want a serious nose dog really because how are you going to keep up with them when they take off for miles following some old scent trail? Scenthounds worked with horses, and they work today with tracking collars, but without either of these things people prefer sighthounds, and if they want scenting ability they like a "hot nose", which is a nose that's best for detecting fresh scents of close by animals on the wind, rather than cold old scents in the dirt. Pointers and other gun dogs provide the best hot noses, rather than scenthounds which provide a better cold nose (and all the tendencies to follow that nose with tunnel vision and etc). Weimeraners are a gun dog with a good hot nose, so yeah a weimeraner is a very versatile sort of dog and will help you find and run down a wide variety of animals, but it's nothing compared to a stag.
