Does your dog like to curl up when it rests? The round dog bed is the ideal shape for "curlers" and gives them the most comfort.
Rectangular
If your dog likes or needs to rest stretched out, then a rectangular dog bed offers the most comfort.
Rectangular dog beds also give superior comfort to older dogs with stiff joints, arthritis, or fusing bones.
Bolster Beds
If your dog prefers the couch, it will love the bolster dog bed. Your dog gets the same sense of comfort, security, and safety it seeks on the couch when it rests its head on the bolster or cuddles against it for support. And it saves your couch wear and tear.
