What does it mean when a dog lays back to back with you?
Consequently, why does my dog lay on his back with his legs open?
When your dog lays on his back with his feet in the air, it most likely means he is confident, independent, and comfortable in his environment. When a dog exposes his stomach, he is usually confident and feels safe. In the summer, dogs choose this position because they can release a lot of heat through their stomach.
Correspondingly, what your dog's sleeping position means?
“The most common posture that dogs use to sleep is lying on their sides with their legs extended,” says Dr. Coren. This means that a dog is relaxed and comfortable and shows a level of trust with his surroundings. Dogs that sleep on their sides need space to stretch out.
Some dogs will sit in "your spot" on the sofa or even roll around all over your sofa as a way to spread their scent and show that you belong to them. When they don't feel that is enough, they move to sitting on you.
