It amazes me how well dogs can communicate and establish rules on the fly. The other day at work I saw a corgi designate a specific corner as "safe" while playing with a few other dogs and everyone respected that (aside from the puppy who is too young to know better). He would go there, chill for like a minute or two, and then get back up and run when he was ready and nobody would bother him in his corner.

Dogs are so good.
