The skies are gray and gloomy, with mist rising up on Pilot Knob. Rain drips monotonously from the eaves of the house and the day is dreary. The only bright spots are the congregation of red cardinals draped all over the rose of Sharon bush. My mood matches the day.Chloe, our little Jack Russell dog is missing. She has been gone now for more than a week, and we look for her every day. Only those people who own (or do they own us?) little house dogs can understand the tragedy of losing a pet. Actually, they are more than pets -- they are part of the family.We never had a house dog until about eight years ago when our daughter-in-law presented Criss with a little Jack Russell, which at first he resisted. It wasn't long until Millie adopted Criss, and she became "his" dog. She was his faithful companion everywhere he went; rode on the backhoe, riding lawn mower, and garden tractor.If he left her in the house for any reason, she would run from door to door, throwing her weight against it, trying to get out. She was his constant companion, and that was her undoing. He had butchered a beef and was transporting quarters of it from the cooler to the meat shop, when another dog chased her under the wheels of his pickup.
