Review on Didog Soft Flannel Padded Dog Vest Harness, Escape Proof & Quick Fit Reflective Dog Strap Harness, Easy for Training & Walking - XS Size: Chest 15-18 Inches, Teal by Boondo Viswanathan

I bought this for my lil pocket pitbull because it looked soft and girly and sometimes she isn't recognized as the girl she is. I had three main concernsHeatDurabilityAnd fit around her chest/neckAs for the heat factor, it's hot where I live in northern CA high 90s most summer days. So far it hasn't bothered her even on a 98 degree day it's like a sweat bandOn to durability. The reviews had me worried and while she's small she's quite a fire cracker. I live in a trailer with a small unfenced yard so she's put on a lead while I'm home with the door open so she can come and go. Un occasion at least two or three times a day something runs by and she goes in full chase mode until the end of her lead abruptly halts all forward progress, she is wearing this harness attached by the provided ring and after a whole month no broken anything not even one stich. Granted she probably will break it at some point if you're doing anything short of this it should last plenty long enough.As for fit I went large because as short as she is she's still a big dog in thickness, just barely. It does loosen when she snaps back from running to the end of her leash but it still fits pretty well, might skew to one side a bit but always sits low enough on her chest that I'm not worried about her throat. I'd suggest going bigger if your at all concerned about medium being too small and don't worry about it riding up on there throat(if you have a pitbull can't vouch for other body styles)Over all I love this harness
