So far that isn't one of my complaints. I did get my wrists yanked on a bit when the dogs scared up a rabbit in our evening walk. I had them under pretty good control, but they put me to the test. (I walk with the dogs on either side of me, the way Cesar Millan says to walk the dogs, and it works well. They didn't bat an eye at the boxer who barked up a storm as we walked past his yard. I finally crossed the street for distance because I didn't want to incite him to jump his own fence. That's what my dog used to do.)
