re: Any tips on how to teach a dog to stop on whistle.

Thank all. It's probably just more reps. We work basics in the mornings before work, I can command sit and walk to distance of about 50 yards and he is solid, can even throw dummies from that distance and he won't break. I'm not in a panic about it happening just looking for ideas I may have not thought of or researched to save us both some pain and time

This is my first working dog and I really enjoy training him. Can't wait for next weekend (dove opens here), LSU football, brisket,whiskey, and pork belly...God bless America
