Panos shares a story about the advice Margaret, the agility trainer, gave to Panos that has stuck with him over all the years!
Being calm and assertive is ok and appropriate at times, however, being animated, girly baby voice is also very handy in other parts of your training.
Have fun with your dog and don't let your ego get bruised, if you need to motivate your dog by being animated, let it go and give it a go. While others need to chill a little and take it down a few notches, lol!
