Our Penny is almost six months old and we are having problems when we take her walking off-lead. I'm wondering if this is normal Vizsla behavior. What she does is she runs ahead of us and then sits down staring straight at us as we approach her, then when we are about 6 feet away from her, she comes running and bites our shoes, clothes, sometimes hands. it's terrible and it scares my daughter so much! I need advice please. I don't have any trainers in my area that I can ask for help.
