Unleashed Pit Bull

Just returned from my evening walk and had an unwelcome encounter. Passed a lady going the other way who was trailed by an unleashed pit bull. He was massive; he looked like the hound of the Baskervilles. I once wrote a column for TPE about inconsiderate people who don't leash their dogs. (I'll try to find it to post.) But those were good-natured golden retrievers that just got me muddy when they jumped on me. This pit bull could've done serious damage. I'm sure she thinks he's a puppy dog, but it's just wrong for people to be so callous. And it's breaking the law.
