anna, what a wonderful post...i have LES thinking about the myriad of reasons, many of which have already been listed, so here's a few of my own...
1-their smiles, alex had a great smile 2- their happy dance on seeing me, paws tapping out their joy. princess peanut can't sit still if i pick up her harness. 3-anytime is a good time for a walk 4- knowing how cool my ride looked with dog heads sticking out the back windows (yes they wear seatbelts and doggles)5- their concentration, some dog has gotta find and remove those dangerous bumble bees from the obedient plants...snap, crunch, ptooie...6-the sound of the sigh and the tag hitting the floor after as we all settle down for the night. wow major LES now, later...
