The WORST thing I've EVER Seen...

OK. I just saw the absolute worst thing in my life. I was out mowing my yard when a white Avalanche comes down the street. It stopped suddenly and backed up. When I looked up again the drivers and the people who live in the house 3 doors down were standing in the street looking at the DOG they had just run over!!!! I almost threw up right there in my yard! I ran over there and the guy asked me if I wanted to see it. I, of course, told him no. I did tell him that there is an emergency dog hospital over by CVS on 34th and Slide. He said he thought it was dead. It was his dog and he wasn't even trying to save it! They did finally pick it up and lay it in the yard. I had to go inside because I was now sick to my stomach. I ran to my dogs and hugged them and kissed them like crazy! I am still sick about it. I can't even go out and finish my yard. I am NEVER letting my dogs out in the front without being on their leashes again. They love my friend Stacey across the street, and whenever they see her they bolt across the street before I can stop them. We've had a few close calls. NEVER AGAIN!!!! My only hope is that the dog died instantly and didn't feel anything. What would I do? I would be a basket case. These dogs are my kids, and I would do anything for them. UUGGHH!!! There but by the grace of God...
