I ordered my PerfectFit harness over the phone, just giving the one measurement required and the breed of my dog (a YorkieRussell) I paid over the phone and received my purchase through my letterbox on the second day after the order was placed, which was what I was told. The harness really is a perfect fit! It's easy to put on, once I'd got the hang of it. And my little dog is very comfortable in it. He walks in a more relaxed manner, and is a delight to take out now. I just need to purchase the lead to go with it now. It will be lighter and less cumbersome. Thank you.
