So my German shepherd has never been trained formally to come or stay... he just kinda gets it and when my boyfriend and I take him to the park/ on a hike, he loves to run in circles, but never goes too far away... Sammy on the other hand, seems to love to test his boundaries and my patience whenever we take him anywhere! I used to live near a dog park that had a small fenced area for dogs under 20 lbs and Sammy loved to run and play there for hours, but now I am nervous to let him off the leash because there isnt really a good fenced in place close by or even at all that I know of... does anyone have any advice or experience with yorkies off leash? do you let your babies be a little free or always on a leash? he is so fast I worry he would get into danger before I could catch up to him...
