Any time you're working in the world of taming animals, you're going to get hurt. But it's a rush that we get.

Calm assertive energy is the energy you project to show your dog you are the Pack Leader. Assertive does not mean angry or aggressive. Calm-assertive means always compassionate, but quietly in control.

I am not brutal or cruel to animals. My mission has always been to save dogs - especially troubled and abandoned dogs. I've dedicated my life to this.

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.

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

Give your dog something to do before you share food, water, toys or affection. This way the dog earns his treat. For example, have him or her perform the "sit" or "down" command.

Owners lavish love on their pets, which is why so many go from non-aggressive pups to being out of control when they're older. People just don't realise their dog must respect them as leader of the pack.
