We have been using the SleepyPod clickit sport harnesses for several years now. We recently tried the clickit terrain harness which is ideal for working dogs especially with the backpack attachment and velcro.

I absolutely love this harness! If I changed anything about it, the only thing I would change is adding a leash clip to the backpack as well. Overall it has a sleek, professional design and we love knowing that our dogs are safe in the car with this harness.
