The reality is, if you have a high-level-energy dog, it's not going to be happy with a one-hour walk. Those types of dogs are going to require more than one hour of physical challenge in the outside world.

The dog is a reflection of your energy, of your behavior. You have to ask, 'What am I doing?' That's the right question to ask.

All dogs can become aggressive, but the difference between an aggressive Chihuahua and an aggressive pit bull is that the pit bull can do more damage. That's why it's important to make sure you are a hundred percent ready for the responsibility if you own a 'power' breed, like a pit bull, German shepherd, or Rottweiler.

Humans are the only animals who will follow unstable pack leaders.

Whenever I've been bitten, it's because I made a mistake. I either misread the dog's body language or let my guard down at the wrong time.

Many dogs grow up without rules or boundaries. They need exercise, discipline and affection in that order.

You can also hurt a dog if it's insecure, if a dog is nervous and then you try to pet him, you can make him more nervous. It's not just the aggressive dogs that you can get hurt. It's also the dogs that you can actually hurt. It works both ways.
