This is the best dog jacket I've found and I highly recommend it. Both of my dogs have this in orange and we couldn't be happier with the selection. The orange is visible at a distance and the reflective strip is a plus for early morning/dark evening light. The fit is generous but if you are in doubt, order up. I've got the large size for my 50 lb oversized Sheltie (stocky build) and a medium for my 45 lb spaniel mix (tall slim/long build). I wish SK would add a size range between large and medium for a little extra length. My spaniel is in and out of the bush and the jacket is holding up to the rough conditions beautifully. Excellent customer service as well.
