Not true at all !! The dogs look happy cause they are happy. The way you train em makes em even happier, ive seen dogs get trained 90% compulsion and still look happy. These dogs are "working dogs" and it is in there blood to work and working is what makes em happy, working for the owner is what makes em happy, and working and gettin rewarded makes em even happier. So comparing a dog to doing let schutz to a show ring dog is totally not the same. Also i would hope you dont need a ecollar to train a dog to run around a ring.
