heres the vid, and no it is NOT US in this vid, we are only on our third beginner class this week.
Exercise is great for energetic (well all actually) dogs, but especially those high energy breeds that get all pent up and antsy in the winter when it's to cold for them(or us) to go outside.
Shiver me timbers, that's a Rottweiler, not a collie. And I've seen that act before, and that's a high falootin hobby indeed if you pursue it, with thousands of competitors. Not to mention the intense training for any animal in that circus. That takes years of work, not a few months either, but good luck to ya anyhew.
It would take years to train a husband to do all that stuff. Please, show us your own video when you get your doggy through the first part of training.
