OK guys, stop the jabs please LOL. First Mustif or who ever I Think the world is perfectly capable of realizing that a good field bred ESS is capable of hunting any bird, anywhere on the planet. Aside from Ostrich and others of that nature LOL. If you need references of how they do on Quail, ducks, geese, grouse etc, let me know. I can give you plenty of names to call that have dogs of mine doing it in all corners of the US on every American game bird just fine and dandy. Some hunt TX quail exclusively, some ducks exclusively and so on. They are very versatile. Most cases great in the house. But as with any breed, there are some slobs too LOL. Rage yes is a show thing as far as I know. I have seen some field bred dogs that just don't get along with others, or will act tough in the crate toward strangers. But never seen any ones just fly across the landscape to attack people or that sort of thing. Mostly they can be annoying wanting you to do something with them LOL. The flag thing got going I believe quite some time ago when some ones dog never cut the mustard in a trial or hunt test so they chose to cut it down. Flags are used to set a coarse, where dogs are still judged by use of wind, control, finds, trailing ability, steadiness, honors and much more. It is live birds, and in most states simulates hunting to the best they can within a certain large field. They are used to keep order to otherwise kayos and be able to do an event in a functional manner. But with anything, if your not good at it, you may put it down. I do both, I trial, and I hunt. The dogs are perfectly capable of knowing the difference. Happy to show what a field champion can do on wild birds any time someone wants to tag along. Good luck in your search and decision. Let us know what you find and if you want help Let us know. Always happy to help a person find a good ESS that fits if that's the way you go. I know lots of good folks.:thumbsup:
