Were they truly pit bulls? If, so, what colors. There is one home that I know of that has three of these.

They looked like mutts to me...I am not good with breeds.  The most aggessive one was a rust color, there was a black one as well and I can't remember what the other one looked like.

Thanks for your good deed! We'll all be on the alert. I've had nasty encounters before. It's very frightening. Pepper spray for walkers, etc. is a MUST! Be careful out there!
