It was VERY hot and humid this past weekend. I didn't want to let Gracie outside but she insisted on having her regular playtime. I made sure to bring out a big bowl of fresh, cool water for her. I thought she'd be ready to come in after 10 minutes but she played fetch for about 35 minutes, taking periodic breaks to lay on the grass in the shade when she needed a rest. She was not interested in coming inside right away! Not bad for a 12-year-old doggiel!
