My parents retired just about the time I was married (long time ago!) and moved about 50 miles away and took my childhood dog, Laddie, with them because I was going to be living in an apartment. They didn't have a fenced in yard and my dad was the official dog walker. One day while walking Laddie a stray dog came up and attacked Laddie while he was on his leash. My dad had all he could do to separate the two but managed to get back home with a very bloody and beaten up dog. My mom later told me she was almost as afraid for my dad's well being as Laddie's since he was so shaken up. The vet was eventually able to put Laddie back together again but I don't think Dad ever felt very safe after that. We have no idea who owned the dog or if it ever did that to anyone else.
