Idk if its certain breeds or just German Shepards, but my old German boy used to love sleeping with the side of his head pressed against the wall (like he was trying to listen in on the other side)
Wish I had a photo of one of those times on this phone, I miss that little idiot 🤧
I guess it depends on how long you stay like that.
I once fell asleep in a Yin Yoga class doing a spinal twist pose, I missed the next 4 poses and woke up in time for shavasana at the end of class. I would not want to hold the pose for much longer than that.
My cat sleeps on piles of Legos and in a box of random sections of wooden Thomas the Tank Engine track. At Christmas she sleeps in the bowl of decorative pine cones. It is not for us to judge what an animal finds comfortable.
My boy sleeps like this too! It's his signature position.
