I am not an expert but, here is my opinion. I have trained 2 labs , 1 GSP and 1 English Pointer. Keep everthing simple, you should not have to tell the dog to "stay", if you give the sit command, whoa command or any other the dog should do just that until released. However, do not use "OK" for the release, pick something that peolple do not use alot in normal conversation. I learned this by experience, if you are hunting alot of people say "OK" alot and the dog heres this and releases. About jumping, I tell people not to lean down to pet the dog right away, let the situation calm down. If he jumps while you are standing, tell the person to turn directly away from the dog. Most times the dog wants attention and if turn away he will not jump. I know this sound crazy but we use the command 4 on the floor. We will not feed the dogs if they are jumping, we repeat 4 on the floor and feed only when all the paws are on the ground, once in awhile somebody might nt get fed that time, but they all learn quick. Then move this command on to greeting people. If they totally do not listen, we lean over and hold the dog down on his side and growl on the side of there neck, they will all give in and sigh.That is the time to let them up.All the puppies we have had begin to think you are a dog and leader of the pack. I have down this in some silly places, but it works and will keep working thru out the dogs life.

I like the following tapes: Obedience by Dan Mar( this works with any dog), Dan Mar "Gun Dog Training", Training Pointing Dogs 1&2 by George Hickox, Training Upland Flushing Dogs by George Hickox. A excellent book is " The Best Way to Train Your Gun Dog" by Delmar Smith

I have taught the neighbors dogs to healin notime using the "half hitch " method by Dan Mar and aslo with Rick Smiths "Wonder Lead".

Just my thoughts. You do not have to follow only one school of thought for training. Use what works for you. I have even had success with clicker training like they use for Dolphins with some things.

Good Luck
