Weird dog

Keely is my 4th dalmatian and I have noticed they occasionally rest on one wrist, but I've never seen any of them resting on both wrists. But today I watched Keely tuck both her front paws under and she looked like she was going to go to sleep until I got my phone out to take a photo.
I googled it and it seems it can be normal, or a sign of affection. It can also be because of orthopedic reasons but I think I can discount those as she's running around normally, enjoying her swimming and was fine at sports training this morning 
Had a nice walk in Cardinham woods this afternoon with my usual friend and her dogs, it tried to rain and we had one clap of thunder, but it dried up so we could sit outside to enjoy our coffee and continue our natter
