1) It's easy to get off and on - takes about 5 seconds to do
2) The harness can fit loosely on the dog and still be completely effective
3) Katie and Louie seem very happy when wearing it and actually play more attention to me than ever
4) Since it doesn't go around the dog's neck the dog can't choke itself.
The leash attaches to a ring that sits on a loose strap in the middle of the dog's chest.
When the dog starts to pull, the location of the leash makes them turn slightly to one side instead of going straight forward as they intended. Katie and Louie learned in about five minutes that the only way to keep going straight was to stop pulling on the leash.
Last week I didn't realize that an orange cat was running by our parking area right as I opened the back gate with Katie and Louie beside me. I could see that Katie and Louie's chase instinct kicked in immediately, but they didn't make any progress towards the cat and my arms did not get pulled out of their sockets. Hooray for these awesome harnesses!
