welcome, and are the dogs fixed? unspayed females are actually the pair of dogs that get along the least. I would fix all the goobers if their not already. I'd also keep an eye on the dominance, let them know that first and formost YOU are at the top and if you have to split them up or seperate them or put them in puppy time out then be sure to do it, NOTHING bothers a puppy more then being ignored. keep that in mind. Lots of toys and maybe seperate feedings might help the situation.
