It looks to me like when the lady shoved Pluto that he tripped off the curb. I'm a little surprised that she grabbed him like that, perhaps she was telling him that he was scaring the child in case he couldn't tell behind the head.

I don't think he intended any harm, but running through a crowded Main Street seems inapropriate to me. It looks like he even bumped a few guests along the way.
