Hello! We are getting ready to adopt our second GSD (mine died 3 yrs ago). I want to keep the new dog alert, active, etc. Unfortunately we have busy lifestyles (baseball in the spring, football in the fall, basketball in the winter time). Nonetheless, my 10 yr old boy wants another GSD and wants to be active training him, etc. With that said, I would love to be able to find a sport where we would not have the committment like search and rescue, but still be able to keep the dog working, active, etc. Any suggestions (besides obedience training)?
