Hi from Spain,
I´m agree with you, Gregg, using dogs for all kind of hunting situations is something as old as hunting is.
Personally, I enjoy trainning my dogs for hunting as much as I do while hunting with them.
It is not so easy to have a well trained dog, does not matter if it is for bird hunting, tracking wounded animals, or just as a retriever.
There is a great book written specially for trainning dogs on tracking wounded deer by bow, and it is written by a US writer. The name of that book is "Tracking Dogs for Finding Wounded Deer", and it is a great book.
I believe that the use of tracking dogs is permitted by the Pope and Young rules, and it should be allowed in some of your states.
Using a tracking dog at your Country, where coyote and other predators live, takes much sense for me.... Of course I undestand that some of you prefer to recover his wounded deer by themselves, but in some cases using a dog is a great and powerfull tool to recover some of those wounded deer that will finally be eaten by a Coyote or other animal.
Trainning a dog, becomes itself a part of my hunting trainning skills, as shooting my bows is.
Best Regards and nice hunt for all.
Emilio.
