I'm a first time corgi owner and my puppy has started biting my pants and leg when we go for walks. It is funny and sad because other people at the park where I walk her think that it is just so cute, but she is just not getting the physical activity that she needs when she does to me. I know that this behavior is "in their genes" because they are herding dogs, but I'm no cow! haha. Any advice would be great! Thanks! :)
