The neighbors dog came into the house for my dog to be himself was active when I looked out the window was down, I called the window because he wanted me at the window to see with food, hehe. not stirred. I looked to see if they breathe and I thought it was but I was deffenitly it imagening. I searched for their dead. Wheen the field where he was training to be a little blood from his ears and nose, head, but it deffenitland was not hit by a car because they do not beat anywere, not broken bones. I can not last long without knowing my child to live, my everything is dead. Anyone have any ideas?
