This so scary. I never even thought of these things until I got Dori and Yogi. Now whenever we are out, I won't even let a big dog get within 3 feet of us. I just feel like its a 50/50 chance to see if the bigger dog will be aggressive enough to hurt them or not and that not worth fooling with. One snap and they could be dead or seriously hurt. People with larger, aggressive dogs always have the advantage in this area and its not fair that they don't keep them leashed and try and keep them away from OUR small ones.
