My corgi Miles has gotten into a habit of barking/herding children. We don't have children of our own, so when the occassion arises at a friend's BBQ or at a dog park, he will bark and scare small children. When it happens I pick him up and bring him over to the children to show them how to greet a dog properly, but it is still embarrassing. Any suggestions? Have you had to deal with your corgi on this issue? Thanks!
