She thinks, I failed twice. If I failed twice I'm going to fail forever. No! That is not the law of life. If you failed twice that means you can learn. It's just a learning experience. It's an obstacle. An imaginary obstacle. She made it real. She made failing a journey of life... Instead do again and make a journey of your life.

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.

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.

Dogs have found themselves in an odd predicament by living with humans. In the wild, dogs don't need humans to achieve balance. They have a pack leader, work for food and travel with the pack. When we bring them into our world, we need to help them achieve balance by fulfilling their needs as nature intended. This takes exercise and discipline before affection, and always maintaining your calm, assertive pack leadership.

Discipline isn't about showing a dog who's boss; it's about taking responsibility for a living creature you have brought into your world.

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.
