All of our dogs have their own "thing", which none of the other dogs do. Happy for instance drinks water from the water bowl by pressing his nose against the edge, slurping the water up the side of the bowl. I don't know how he can stay hydrated that way, but he does. When the water level is low, his nose gets all wrinkled up, because of the pressure. He's so weird.
Denny's "thing" is his beautiful play bow, often followed by a jump like a buck or a goat, before they crash their heads together. Unfortunately it's so random, that I have not yet captured it.
Maggie's "thing" is leaning.
She loves desk chairs, and when they turn, she just walks with it.
When she was smaller she jumped up on desk chairs in the house, but she's getting too big for that now.
This was very early in the morning, I haven't even turned on all the lights yet, when she jumped up on the chair. At the time this was something I just realized she liked to do, and got a not so great shot of it. I didn't know she would do that again, and again.
This is my basement desk. I have one in my studio, equally cluttered as well.
Do your dogs have their own "things" as well?
