Why do dogs lay with thier front paws crossed?

Mine doesn’t, he actually sleeps on his back with legs spread and straight up. At work so will add link to picture. Btw, he’s a Dachshund!

If you look at the elbow joint, slightly rotating the shoulder joint means that the full weight of the torso does not rest directly on top of the bone. If you rotate your own elbows away from your sides, you’ll notice that you hands move toward each other. In the case of dog legs, they will sometimes cross their feet so that the elbows can move even further out. It’s just more comfortable.

It looks classy.

Yes it is funny how they do this, I thought it would inhibit blood supply to paws.

I wonder the same thing, my dog does it all the time. She does have long, thin legs relative to her body. She is whippet/kelpie cross. It must be that their physique makes it more comfortable.
