Idea Exchange: A leash trick so your patients don't disappear

We've all seen dogs with big necks and small heads get loose by slipping their collars over their heads. In a pinch, you can quickly turn a dangerous collar into a safer harness by wrapping the leash under a dog's chest and locking it under the leash clasp. It works best with a 6-ft leash.
