That's a large setter you have there. Is it from Ryman/Hemlock lines?

Also, setters can be stubborn but no more than your usual hunting dog. I believe it has to do with their drive. It overwelms them at times. My setter has to chase things - even though she's afraid of them.

A little training goes along way with setters. You'd be surprise at what they can retain. But keep your commands short and firm and don't talk too much when training. Then praise like the Dickens.
