Since you don't have much time on your hands, a bark collar may be the only short term solution for that problem. I had one for a problem barker that I got from Cabelas, it activates on the 3rd bark and gives progressively higher corrections if barking continues. It worked very well and fast.

Is he crate trained? I would highly recommend a crate for him. He's in a new situation and crates can have a calming effect on otherwise hyper or over-stimulated dogs.

I would also recommend getting him fixed, it takes hormones out of the equation.

Practice calmly leaving, if only for 10 seconds and then calmly coming back into the house, ignoring any wild behavior.

I wish you the best!!
