I am anything but a dog lover. However...

...having found among my papers, for no reason I can imagine, this item - obviously written by someone who is - I was too charmed not to share it.

If a dog were your teacher, you would learn stuff like this:

When loved ones come home, always run and greet them.
Never pass up the opportunity to go for a joy ride. Allow the experience of fresh air and the wind in your face to be pure extasy.
Practice obedience - when it's in your best interests.
Let others know when they have invaded your territory.
Take naps and stretch before rising.
Run, romp and play daily.
Thrive on attention and let people touch you.
Avoid biting when a simple growl will do.
On warm days, stop to lie on your back on the grass. On hot days, drink lots of water and lie down under a shady tree.
When you're happy, show it. Dance around and wag your entire body.
No matter how often you're scolded, don't buy into the guilt thing and pout... run right back and make friends.
Delight in the simple joy of a long walk.
Eat with gusto and enthusiasm. Stop when you've had enough.
Be loyal.
Nver pretend to be something you're not.
If what you want is hard to get, dig until you find it.
When someone is having a bad day, be silent, sit close by and nuzzle them gently.
