I live in a neighborhood where every street has a cul-de-sac. Outside our neighborhood is a busy road. About 6 months ago our 100lb Great Dane escaped out the front door while we were bringing in groceries. My wife and I chased her around the neighborhood trying to get her back. We lost sight of her and she eventually ended up in the middle of that busy road. A young college aged kid saw her in the road stopped his car and chased her back into our neighborhood. We cornered her and I grabbed her collar. The guy headed back to his car after the dog was caught. I should have got the guys name. I was so angry at the dog I didn’t really know what to say to the him but I am still so thankful. It could have been a very sad day for our family without his help.
