I have spent many years living with and hanging out with dogs, and I have found the experience highly educational, as well as entertaining. They do not spend a lot of energy on other times or places. They know that the future contains the past, so the best way to know what went on is to move forward. With your nose to the ground.
Dogs are never judgmental.
They are well aware that everything in the world is there for their enjoyment and they take full advantage of that. You will never see a dog enter a new place with prejudice. Every new environment is an opportunity for exploring and learning. The dog's approach to relationships is to love everything unconditionally, and as often and as much as you can. Everyone who is accepted as a member of the pack therefore receives unlimited love and invitations to play.
