Do you want to find out how sociable and outgoing your puppy is? Then try this little experiment:
Put a few toys down in the room. Quickly walk away from your puppy and then observe his reaction:
*A positive response would be the puppy running happily after you, regardless of what else might be occurring.
This shows that the puppy highly desires the company of people, a trait that is advantageous. This puppy should be easy to train and should learn to focus well on you instead of distractions. Most puppies will follow a human at the expense of playing with toys, but not all.
*A different response would have the puppy ignoring you and investigating something else, perhaps a toy on the floor or a sound coming from another room. This puppy may not value interaction with humans over his own desire to investigate his surroundings.
This is not always a negative thing, but it's a perfectly nice little test to try out with very young dogs. Some dogs are not as 'locked on' to human interactions as others. But remember, dogs personalities change with age and good socialisation.
