I put my young dog outside while I was riding the exercise bike and she hasn't come back. I went out in the pasture with a flashlight and drove all around the roads but I can't find her. She has never been gone like this. I'm thinking she has to have been killed or she would be home begging to get in by now. Can't sleep but can't see well enough to keep looking in the pasture. I'm afraid one of the horses may have kicked her. and I feel awful that the last thing I said to her was 'not everybody wants to play with you every minute. You're being obnoxious."
