I have a nine mos old Golden Retriever with whom I am actively involved in ongoing training. He goes to a Doggie Daycare twice a mos & is very well socialized. We go on daily off leash trail walks as long as the trails aren't a mud bowl. I have a large fenced in back yard for playing if the trails are too messy. I am a shift worker therefore available quite often during the week & weekends. A exercised dog is a happy dog.
