Ah, I could see plainly in the photos that these dogs were new to each other. I failed to read your post before looking at them and went back to read it to see if they were actually new to each other.

They seem to be doing fine though. The vid of them was funny. I so miss having my Jess and Mist when they were young. Now Mist is gone and Jess is 13, it isn't the same. I'll be getting another pup soon so I'll get to have an active lunatic again and see some proper playing like with yours.
