How does a dog learn to have great recall?

OK, I have a question for all of you dog training pros out there:

If your dog has great recall, how did you train him/her?

I’ve always thought about this, and one of the most puzzling things to me is that the dog I know with the BEST recall wasn’t that seriously trained (or trained with methods that I disagree with, or have been taught are flat-out wrong).

Dublin is the dog with the most outstanding recall that I know. She lives, as you may remember, next door to my parents and my dad considers her his surrogate dog; he spends a ton of time with her. Dublin will stop on a DIME when you call her name. Dad told me that this past week, she got out of the gate to chase a cat in the neighborhood, but she stopped immediately when he called her — in the middle of a cat chase! And ran right back to him. This astonishes me, and yet I’ve seen her do it. She comes right to you, every single time. Dublin responds to anyone who calls her name, too — even to her family’s little girls.

But this is what bugs me. When I asked my dad why Dublin has such great recall, he always tells me this story: “When Dublin was a puppy, she was about to wander into the street, so I grabbed her and smacked her pretty hard and told her not to do that again. She really learned, though! She’s come perfectly ever since.”

All of the reading and training I’ve done tells me that this can’t be true, that dogs don’t learn from physical punishment, that Dublin must be afraid of my father, etc. If you’ve seen them together, however, it is impossible to believe that she comes out of fear. This dog trusts my father utterly; she adores him. In fact, my dad might be the only person that Dublin truly loves; she’s more or less indifferent to everyone else. I’ve honestly never seen any anxiety or fear when she interacts with him. Furthermore, he doesn’t use physical punishments with her on a regular basis. He swears this was the only time he ever smacked her.

Dublin has not really received any formal training; I don’t think she even knows how to go “sit” or “down” on command, but she is an excellent Frisbee player, athlete, and all-around wonderful family dog.

So, what do you think? Why does Dublin have such great recall? Can it really be the smack from my dad when she was a puppy, as he claims?
