Have you ever had a dog this vocal?
Oh yes! My boy Sunny would vocalize on cue, and even if you picked him up he would continue until he was done. I have video somewhere of him howling while being held upside down.
I had a friend on facebook refer this site todya. It looks great for trying out the various DVDs. I have been buying one dvd every couple of months and really like having DVD training to help me with my classes. When I first started doing rally there were no classes within 200 miles and I learned everying from a DVD, even took 2nd place in rally novice at the whippet nationals with my girl.
That looks like a great site! Thanks for sharing it.
cleanrun.com has videos on demand. mostly agility-related videos, but they also have the control unleashed stuff.
