Be Like a Tree

if yes: pet under chin

Put your hand in a fist with palms facing down and reach toward the dog - remember, you are still several feet away. It is best to pat the dog under his chin, on the side of his neck, along his back, or scratch his chest in slow gentle strokes rather than running your hands quickly over his body.

If No:

If the owner or dog says "no", move on and leave the dog alone.

Most dogs do not like to be patted on top of their heads, so avoid this area.
