Thor | Hハーネス

Adjusting this to fit my dog took about ten seconds and it hasn't slipped once on our walks. The two d-rings on the back are handy depending on whether I want the leash short or loose. Honestly the best-fitting harness he's had.

The two d-ring spots on the back are handy — I clip the leash to the front one for walks and the rear one when he's tethered in the yard. My dog pulls less with this on than his old step-in harness, and it goes on in about five seconds.

The full adjustability is what sold me, since my pit mix is broad in the chest but narrow everywhere else and most harnesses either choke her or slide off. This one actually stays put on our morning runs.
