Fewer wrist sprains!
We got an XL, based on the sizing chart. We should have gotten a Large, but there is a lot of room for adjustment, so the XL is working.
Our Pit mix had been trained with a shock collar, but stopped responding to the unit. Although small for a Pit, he's strong and his lunging was difficult to control, even with a slip lead.
The harness with its chest-ring has given us more control, and it has definitely been easier to walk him through areas with distractions.
