one of the worst days of my life happened when alex slipped out of my old apartment, by opening the sliding screen door by himself and walked the 3 blocks to the park. i didn't discover he was gone for nearly an hour. i have my number and the vets number on 2 seperate tags, and REWARD in largest letters. the guy who caught alex called the vet and called me. the vet had sent one of her techs to pick him up by the time i found where alex was. my stomach still clenches at the thought of his wandering; what would have happened to an epileptic, regular medicine needing dog i cannot bear to imagine. those tags are worth every penny and more
