so... I have a yr and a half yr old gsd/border collie mix and a 4 month old GSD. Both can get pretty rowdy! We usually just let them go at it until they drive me nuts and then tell them to "quiet". I can separate them if I need peace but now I'm babysitting my Parents in law's puppy (my 4 month old's litter mate) and they are always almost uncontrollably going after each other. It's mostly play, a little dominance establishing, and EXTREMELY LOUD. We also bring the pups to work with us and their noise is extremely frustrating when trying to speak on the phone to customer. My MIL treats it as though they are puppies and we just gotta let them get it out where as I believe there is a time and place for rowdiness. Do you multiple dog owners have rules for how rowdy your dogs can get indoors or do they just "go at it?"
