Cooper's blushing at the compliment. Or maybe that's his dust mite allergy…
Cooper's harness is the Gentle Leader Easy Walk Harness (they also make a head collar). It's designed to stop pulling, as the pivot point is at the front. When the dog pulls, it generally ends up turning right back around facing you! Really great for getting the attention of an aloof B.
We also found that this was nearly escape-proof. Between his B nature and time in the shelter, he had some pretty bad leash habits when we got him. But after the Easy Walk, beginner obedience, and patience, he's now doing just fine with a normal collar and Flexi lead.
