<human>: I have a 10wk old Bernese called Hilde and a 7yr old Rottie called Thor who absolutely adore each other. Thor is amazingly patient and gentle with Hilde, teaching her the ropes and often "putting her in her place" with growls but never doing anything that has made her whine or any bit fearful of him. I'm so happy that they get along! 

The problem is that two of them constantly wrestle, growl, and run amok when they're together. Outside it's awesome – they chase each other and play with toys and it really tires everybody out. Inside... not so much. Their playing is rather cute right now but I know once Hilde reaches her full size it will be completely obnoxious. I would love to teach them that roughhousing is OK outside but not permitted inside before it becomes a nuisance. 

Thor is awesome and calm. He would be happy to lounge around inside and is never the instigator. Hilde on the other hand sees Thor and goes hog-wild. We've been working on rewarding calmness and it's really showing when Thor's away, but the second he walks into her view she's jumping and running and generally being crazy. She'll lay calmly if one of us is actively working with her but the second our attention goes elsewhere she's back at it.

I want to make sure that I'm only teaching them that inside is off limits – it's fine for them to run and play outside! Does anyone have experience dealing with this? Maybe some tips that I haven't tried yet?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Dogs constantly roughhousing inside, always instigated by the puppy. Would love to be able to teach them that that's an outside game only.
