Aggression is not a breed thing. Its a state of mind, and it comes from how the human is with the dog. There are four levels of energy, regardless of the breed: low, medium, high, very high. The idea is to get a dog in your same level or lower than you.

Anything that can create balance in dogs is great. If veterinarians can give you the solution and give you why this is causing the behavior, of course. Anything that is good for an animal, let's do it.

With small dogs people don't reinforce the same behavior that they do on a larger dog. If you are a driver no matter what size car you have it doesn't matter. Same thing goes for any gender. All the rules are the same.

Mother Nature's ruthless to the weak, but isn't arbitrary cruel or negative. Mother Nature saves aggression for extreme situations, and instead uses consistent leadership--to help keep things running smoothly. Mother nature doesn't rule by fear and anger, but by calm strength and assertiveness.

I love my dogs and I give them affection all the time but it has to be at the right time or they get confused.

Always walk out the door ahead of your dog when leaving the house. This will show your dog who is in the leadership role.

But just because a person goes to Harvard doesn't mean he's balanced when he graduates, and just because a dog knows how to obey doesn't mean he's balanced, either.
