We have been blessed with Neiko from Lady and Kevlar for almost two years now. We have been through your obedience training as well. Recently Neiko has taken to walking out of the yard and into another yard and close to the road. The real problem is that he will not come when I call him. He stops, looks and keeps walking. Any other time in the yard or the house he listens and obeys. I am at a loss on how to rectify this behavior. Do you have any suggestions? Thank you so much!!
