Avoid biting when a simple growl will do. When you need to go outside, be insistent. People are not always paying attention. On warm days, stop to lie on your back on the grass. On hot days, drink lots of water and lie under a shady tree.
Water tastes better if it's flowing and cold.
Walk in the rain and smell everything. Always walk in puddles to see how deep they are. When you're happy, dance around and wag your entire body. When you leave the house, run around the yard a few times real fast. Delight in the simple joy of a long walk.
