Lincoln does this also but Truman is all about making his nest. This is him in the living room on what is normally Lincoln's couch. The blanket next to him is what he was working on the 10 minutes or so prior to the picture. Before he started it looked like the one on top of the couch. Folded in half and nicely layed down.
He spins and digs, spins more and digs more and next thing you know a couple more spins and he flops down.
He is not picky - he will use the dog bed in the family room, the blanket like you see here - well any blanket actually - and of course the quilt on the futon in my sewing room when I am in there.
Do your dogs do this?
I think the flash woke him up on this one.
