Kaia is almost 4 months old and up until now she has only been walked on a leash. She has so much energy that I feel that on leash isn?t enough. When is the best time to train her to walk off leash? Any training tips? I?ve had her off leash in the dog park but there weren?t other dogs around. I?m afraid she?ll just take off on the trail. She comes to me almost all the time in our home environment but I worry when there are many distractions. Any advice will be wonderful. Thanks.
