Whats the worst thing that has happened to you while out walking your dog?

wow that would scare me to death if my dog got shocked. The worst thing that has every happened to me while walking my dog is when my pitbull great dane mix fell down and had a seizure. Luckilly I was on my street so I was able to get a neighbor to wait by him as I ran home to get his medicine for seizures. Hes fine now but hes becoming an old dog and slowing down.
