Keegan is still a puppy, and I wouldn't worry about such seemingly drastic techniques. I think that more important than that is just consistency in all the other ways you say "I am the big dog here" as she has sooooo much to learn that some things make take a while to sink in. Meanwhile, enjoy those puppy toes, the fat tummy, all the sweetness that she is! She sill continue to "test" you as she grows, but as long as you remain firm and consistant, all should be well two years from now. (We DID warn you that Goldens [and Labs, for that matter] have very long puppy-hoods, didn't we?)
