I have been using the Kurgo Swivel Tether for years. I love it so much, I bought one for each of my dogs for all of our vehicles so we don't have to move them from vehicle to vehicle. They are always ready to use. The construction is quite robust and it is a super secure way to tether your dog's harness to a seatbelt.

I added this to the Kurgo "direct to seatbelt" tether and it gives a little extra length and a solid swivel carabiner. It keeps my pup safe and the tether untangled.

I have rescue dogs that are fairly anxious car riders, and can freak out easily at the unexpected. This worked will in conjunction with the Kurgo harness, for multiple dogs on car rides 4+ hours long. No biting at the lead, gave them comfortable range without endangering the driver, and it was easy to attach and detach for pit stops. Definitely recommend.

It works great so my dog could move and lay like she wanted too.
