I'm sure my dogs wonder what is so fascinating about looking at a computer screen for hours. Sometimes, Max will come up and nudge my hand off the keyboard to let me know, times up. I am fascinated how they can play with the tubes (left over from the fence) for hours. They will pick a tube that has a live critter (usually a baby iguana) and terrorized the tube for hours. Max will pick up the end of the tube with his teeth and drag it around the yard. Mela has developed a clever maneuver of jumping straight up in the air and landing in the opposite direction, hovering the tube. Since these photos, I have stacked all the tubes and wired them together. When the rain stops, I'll probably let them play with them again since it does amuse them for hours and I can be on my computer undisturbed!
