Romping on the floor with dogs sounds like something people should do if they have dogs. Shenanigans are misdeeds of some kind, things you're not really supposed to be doing. But maybe it's context too . . . perhaps if you were avoiding getting yourself showered and dressed up for some event you didn't want to go to by romping with the doggies.
BTW potato chips and onion dip sounds yummy. With or without shenanigans.
