In case you missed it, here is my video on the evolution of dog-training methods. It’s also on my homepage, but since you seem to be interested in this kind of thing, I’ve put it here for convenience.
Training methods matter. You are your dog’s guardian, and as such you are responsible for your dog’s wellbeing. You will want to educate yourself on the different training methods (and trainers) are out there. Remember, some methods can be downright dangerous for your dog’s health—either physical, social, or emotional.
This video will help you do just that. Grab some popcorn, though. It’s about 20 minutes long.
Enjoy!
