How terrible, for you and the doggies!!! They are probably having the time of their lives, having been confined to a garage most of the time! I feel for you Heather, and also the dogs. I guess they aren't crate trained??? How could the owners be so clueless that this would be their behavior? Maybe you could do some short term obedience training while they're there. And sounds like they need so exercising to work off some of that energy!
