Are Armpits a Design Error?

Armpits sweat uncomfortably and often stink, unless you take measures to prevent that. Dogs have no armpits. But if you turn a four legged animal upright, and let the front legs hang down from the shoulders, you get armpits. A better design for human arms would be to have them stick straight out from the trunk, with an omnidirectional elbow, or at least have them hang down from cantilevered clavicles, away from the trunk. Even an octopus does not have armpits. The transition from four-legged to upright locomotion was not well-planned, with respect to armpits.
