What's the difference between a calming donut bed and an orthopedic bed?

Donut-style calming beds use a raised faux-fur bolster to give anxious dogs a sense of enclosure and a built-in head rest. Orthopedic beds prioritize joint support via dense foam and a flatter sleeping surface. Anxious dogs that nest and curl up tend to prefer donuts; sprawlers, seniors, and large breeds with joint issues do better on orthopedic foam.
