Puppy
Aptitude Test

In order to find a good working dog, you need to test for certain aspects of a puppy's personality. Check to see if a puppy is dominant or submissive by placing him on his back. If he fights, he is dominant. You generally do not want to pick a dog that is overly dominant, as they are not as trainable. Try testing the dog's retrieving instinct by tossing a ball or crumpled paper. He should show some interest in interacting. Also play with the dog and then walking away. Whether he follows you can be an indication of his pack drive. You don't want a dog that needs to be too independent.
