Side Sleeping
Many dogs like to lie down on their sides during naps. However, they don’t stay like this for long periods of time. It often means that they will need a longer time to stand up and defend themselves in case anything comes up. A dog in this pose is one without any worries whatsoever, which is a good thing.
Superman
What could possibly be cuter than a dog doing the superman pose? After they tire themselves out, they like to fall asleep on their belly and spread out their limbs. It only really happens when they feel truly exhausted. Pups do this frequently because this pose allows them to get up easily.
