Theres no bad pitbulls...just bad people...

I came out of an elevator and there was a pit bull on a chain and an old lady trying to hold it back. Gnashing its teeth. Growling, barking at me... WTF! . I think I peed a little! I grabbed my dog spray and was about to hose that ***** down but the lady started screaming at me that the dog was barking at squirrells...we were inside an apartment building! F that, that's the second time a pit overstepped its owner and lunged at me for no reason. I wasn't on either of its properties....not good.
