DURI harness and leash set that provides a comfortable fit without constricting the neck. - Color: Blue - Brand: DURI - Size: S (Size details are in the image) - Included: Leash - Features: Non-constricting neck design Thank you for viewing. I tried it on once, but the size didn't fit, so I'm selling it. I matched it to my dog's neck size, but the chest didn't fit. I bought a larger size. It's easy to put on. I have tried it on once. Please understand before purchasing.
