i agree with your premise on the drive griff but that's a problem inside the hunting group as a whole. they are all so scared of obed because they are sure it will "make a dog lay down on point", "take the drive out", etc.
when i said it can be doen in the back yard i should have premised it with the fact that i was talking of a dog that had basic obed. then again , all my dogs have obed put in before we do anything else though it is geared to the age of the dog and his individual level.
if the dog has obed he has obed. if he doesn't. these are the dogs that can't sit still and drag the owner from place to place on the lead while the owner yells sit, sit, sit, sit sit, down, sit down , sit! then they tell ya "he always does better than this at the house."
he does not!
if your dog has no obed foundation he/you will have a hard time overcoming any kind of control situation.
as for drive. look at ft/ht labs. they are required to sit and stay regardless of the birds falling around them on their marks as well as in the honor position when they have to stay while another dog busts out of the boat and gets the bird they believe is theirs.
also in flushing dogs the standard for proper handling is the dog hupps(sits) on the flush and waits to be sent after the downed bird. if it was so tough to stop a dog in drive how do you think these practices would have ever been developed.
and btw, if you have a candidate that you think is in need i get paid to do the very thing you talked about. send him to me and i'll hook you up. i offer a no train-no pay guarantee
i was showing a new client one of my gsp's hunting as a demo. the dog was flying across the field at her normal 20mph lope and i hollered "whoa". she froze in place until i blew the hunt whistle again. the client called me a "showoff". i told him that was not showing off and it was what should be normal for any pointer.
as for the barrel, if you found someone that had done more than bird dogs they would tell you the same as me.
i don't think you will find too many bird dog trainers well known for their obed but when you do (jim dobbs) they won't have a barrel anywhere around.
