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.
Harness seems well made and just what i wanted for ms b. This one is super durable and good quality. Great for walking in the woods. Sturdy and well made.
The padding is good and it doesn't chafe her. The cords hold * bags, so theres that lol.
Two months old, used 3-5 times per week for 30-60 minutes at a time, and falling apart. D-ring on the chest attachment came off because the * stitching on the retaining loop gave way. Would definitely not recommend.
