It fits him well and lays snug to his body. Goes over top of chest area, so no choking. Fits good for my yorkie poo.
This item is very poorly made. Too tight for our little 4lb puppy. The harness fits fine around the chest, but the shoulder part gaps open.
Second belly strap is super close to his *. All areas of contact are adjustable. Second strap lands geographically across my boys.
Small won't fit a jack russel. The back strap is inconvenient.
