OMG I'm so sorry it happened to you...You just have to watch out all the time with those little guys. I had 2 scares so far and I haven't even been to a dog run yet - after my Pepper was lounged after by 2 big dogs, I'm not even planning to take him where there are a lot of dogs off leash. Sad to say but I see big dogs running without leash a few times a week here in Queens. One of them is a K9 dog - a Shepherd and he's very well trained, but the other ones run around as they please
