He will turn up, just give him time. Worst day in my life is when my best friend was takin from me. He got loose and followed me out to the shop, and I stopped and was out of the pickup to try to get him, and a local electricity service pickup hit him, on porpuse, he drifted over and got him. right in front of me, he never even stopped. I just picked him up and took him home, I was only a freshman in highschool and was in total shock. My dad called his boss and got him to stop by the house, when he said you killed my kids dog, he thought a kid, not a 6 foot 195lb freshman in highschool, and said I could take a swing at him, I would have loved to but it wouldnt have changed anything. Still brings a tears to my eye. But your dog will come back.
This freaking sucks !
