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.

Some dogs could play fetch all day long, while others have absolutely no interest in chasing a ball. Some might love "find the treat" type puzzle toys and others may completely ignore them. The important things are that your dog finds the toy interesting without becoming obsessed over it, and that it is size and safety appropriate for your dog. A Chihuahua is probably not going to be a good match to a Kong as big as she is, and you wouldn't want to risk having your Malamute swallow one of those smaller size tennis balls.

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.

Birth, life, death is a cycle. And they're all beautiful, you celebrate all of them. Animals do grieve, but they move on. That's the lesson behind animals.

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.

The pack is very important for a dog. Once you give him the right pack and the right energy, you look at him.

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.
