Yes this small booklet will be a great help. If you just added another dog most likely there play will consist of long sessions until it gets old "saturate" then it should slow down. As for rough play that will come down to a debate among some people as it is parenting as to how rough to let it get before me interven. Just make sure that the dogs are roll reversing the play "demeanor shift" after a few seconds on chases then they switch. If this is not happening then it's bullying. Also try and learn body language so you can tell if one is giving distance behaviors, appeasement or calming signals.
Start with booklet and have fun remember always reward good behaviors oh want to see again.
Yeah, they're reversing rolls. The older will jump on the younger... then it's the younger jumping on the older. They're both equal opportunity rough and tumblers.
The older one has indicated she wanted distance a few times. Mostly by growling, and then some barking. The younger rolls over to say, "ok, I'm not a threat, I get it." Usually that occurs when the older dog is tired or the younger crowds the older (or is generally being annoying). No big altercations, but I watch them carefully, especially with toys.
There are some issues with resource guarding (on both sides). Right now they're separated when I'm away (puppy is in a pen). When I first gave them both bully sticks, there was a bit of a situation. Now, however, they seemed to have learned to deal with each other. Each wants the other's bully stick, but now they'll wait until the other has dropped the bully stick to grab it rather than trying to make a more aggressive play for it. All this is in my presence, of course. If I were to leave them together while alone at some point, all toys, treats and anything they would find special would be away from their reach.
What they do resource guard that I can't put away is me. They both want me and the older dog can get snippy about it.
