Just Kairo being Kairo! Will chase a ball anywhere, anytime. Don't want him jumping too much, but I'll mix in a frisbee from time to time to keep playtime fun and interesting. The next door neighbors have little grand kids, and today when we were outside, they kept yelling, "We love your German Shepherd!" Kai barked once as if to acknowledge their presence and went about his business. Needless to say, we had an audience of 5 and 6 year-olds while we did our training and playing this afternoon.
