I think, what's important to capture here, is that typically "commercial" dog trainers...yes...those that assist pet owners (with almost ZERO knowledge of the K9 kind), don't really work the reward/praise like those people who work dogs. TIMING + PRAISE/REWARD=WANTED RESPONSE/BEHAVIOUR. Yeah...one can show up with his/her dog, to a dog training class, with his/her bag of treats, and toss one morsel each time, the dog does something good, (with little said to the dog), but honestly, that's going to quickly deflate like a pin popping a balloon.
I don't want a calm dog when I'm training it to do what I train it to do. I want an overly-excited, freak! Unfortunately, to mainstream pet owners, this behaviour is quelled. People can't handle or tolerate it.
But I digress. I liked SitasMom's strategy though. That is an excellent way to deal with distractions. What the hell....one's in a chaotic ob class, with a bunch of unsuspecting pet owners. Great idea!
