I'm more afraid that an uncontrolled dog will hurt one of my dogs than I'm afraid it would hurt me. Even if they're not obviously out of control. There was a guy and his dog sitting next to the entrance at Walmart a couple days ago, and I chose to use the other entrance rather than risk that dog (who was really just laying there sleeping) would react and hurt Logan. If I see a dog on a flexi in public it makes me furious and I will actively avoid getting within 30 feet of it.
