Some businesses used to rent guard dogs through trainers instead of keeping their own. The dogs would be dropped off by the trainer after hours and picked up again in the morning. To be honest, I don't know if that's still done I read about it in when I was a teenager). I'm wondering if that's what he's talking about. Don't get me wrong, I'm not supporting this guy. After looking at his website, I'm with all of you- the guy's a jerk. Just wanted to point out that "renting guard dogs" can be a legit business (doubt it is with this guy, tho).
