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.

The seal belt attachment is just perfect. The leash is great as well and comfortable. The seat belt leash is awesome too! Comes with leash, harness, seatbelt tether strap and a velcro storage strap.

The quality of the harness is top notch. Seemed to have been used by others, repackaged and sent out again as new. Good price for the items.

It is very sturdy, but nicely padded. The clips are very sturdy. The latches are thick and sturdy. It is sturdy enough to withstand their weight and pull at times.
