Nope. Never off leash. Never will be unless it's during a trial or dog park. No need to for us. If they need some room to run outside of our yard, they get put on 30 foot leads. Kimma is the only one that I will let drag a long lead, and only when we are actively training (usually in an open field). If another dog comes near, she gets put in a down/stay and I will either go sit beside her or step on her lead (not that she tries to go anywhere, but just in case).
I've had too many annoying experiences with people that do not have control over their off leash dogs, and these dogs usually end up coming up to my guys. It really bugs me, especially having Pentti who is "dog selective" and Bubbles who is reactive (Kimma has gotten tons better with her reactivity, but she definitely doesn't appreciate being charged by random dogs). Now, if there's someone with their dog off leash and they have complete control, then I don't care - I just rarely see that at the parks I frequent....
