I wish that I could talk to dogs

I am in my 2nd week of the Couch Potato to 5K program. I've never been much of a runner, but I've decided that I could be.
A couple of my friends began and after how I heard how they were doing, I decided that it might just be a good program for me as well. I want to do a 5K in the future. I know that my 70, or possibly 80 something, neighbor will still kick my butt, but I want to finish a 5K. So far, my refabricated ACL is holding up vs my original ACL in the other knee.
Today, I had Cinnamon running with me, which, BTW is like trying to put a leash on a deer. She loves to go with me, so I take her almost every time. We were running along and she spotted something that caused her to stop in her tracks. She froze, and began to back up. Freaking out.
It was a baby stroller with full trash bags tied all over it. Something that is usually being pushed by a homeless person on the street. This was just sitting at the curb. We could not pass it and needed to turn around. Cinnamon didn't calm down until we were half a block away from it.
It's not as odd as Pumpkin's irrational fear of aluminum foil when we first rescued her from the shelter, but it was odd.
I wish I could ask her what was wrong. How long was she a stray on the street? What happened?
She is sleeping quietly on the sofa now (and drooling onto the floor)... safe and sound, and that's what matters.
