I know how frustrating that is. I get that kind of crap from my famliy and some of my friends and some of my club instructors. Go figure.
I did try the old ways including yank on the neck, smack on the nose, rolled up newspaper and yelling and none of it worked how I wanted at all. ie dog would turn into a floppy custard on the floor - and generally had no idea what she'd done wrong, or what I wanted her to do instead.
So I had to learn about operant and classical conditioning or I'd have a dog that would still be at the park or beach now or squished by a car following/leading me home at a non-catchable distance.
