For both of them, repeated biting of each others' necks appears to be a favorite pastime. Genghis also loves taking Star's legs in his mouth, and they both love flipping over on their backs with their mouths open, gnashing their teeth in each others' general direction.
All this goes on in near-complete silence. There's the occasional growl, gurgle, or snap, but most of the time they're totally quiet.
There's a feeling of total engagement, complete camaraderie, almost what you would call calmness. A kind of doggie Zen, where the two are completely on the same wavelength.
Until recently, I never saw this kind of play with Star and Fozzie. They've always gotten along pretty well together, but their play has had a different kind of intensity, with more running, more tugging, more loud vocal yodeling and arguing.
I thought that Fozzie was just like most normal dogs, in that he didn't really enjoy having his neck continually bitten and so couldn't get into a play session with Star.
No growlies, no snappies, just mutually enjoyable biting, chewing, wrestling, and a bit of humping.
I was happy to see that they had that capacity! Star and Genghis seem always to be in the mood for the same kind of play, but it was nice to see Star and Fozzie able to get into that groove too.
It doesn't surprise me that Fozzie is not always up for the kind of rough play Star loves, as I think of Fozzie as a very complex dog. (I hope my sister isn't reading this. But if you are, yes, I know Genghis is a very complex dog. Maybe Star just brings out the big goof in him).
Do your dogs have different play styles? Have you noticed that some are incompatible because of these differences, and just need to find the right playmates?
