I've been doing it for over fifteen years with three different dogs. We only ride on residential streets and sidewalks.
Our current dog has a lot of training; she does agility and is a therapy dog so she is well socialized with humans and dogs. She won't run after a cat or another dog. If she feels threatened, she'll try to cross behind me and put me between the other dog and her. Usually she can't do when I'm on the bike; I keep the leash short enough so she can't. Where this incident happened though is at the start of a three-block stretch where she usually runs. She knows this and will start nipping at my foot and leg when we turn onto the street. As we go faster, I let out a little lead. I had just done this when the dogs ran out so she had enough lead to cross behind.
My feet wouldn't have been scraped up if I hadn't been wearing flip flops. It was painful this afternoon peeling my socks off the open wounds.
We go pretty slow. The video is our normal pace.
Ouch, sounds painful. I hope your feet heal quickly.
