Training a dog, to me, is on a par with learning to dance with my wife or teaching my son to ski. These are fun things we do together. If anyone even talks about dominating the dog or hurting him or fighting him or punishing him, don't go there.
I grew up on a farm and my grandfather quit school when he was 12, but when it came to common sense and animals, he was the smartest person I've ever met, before or since. He taught me that to touch an animal is an earned privilege. It's not a right.
Training a puppy is like raising a child. Every single interaction is a training opportunity.
You can instill fear in your kids and get them to mind, but they won't function better in the world and your relationship will suffer greatly.
