By far the best sweater-weight coat I have ever found. Follow the measuring instructions carefully - and note that sizing is different from some other Pomppa coats - but this fits my son's Chihuahua x Dachshund cross PERFECTLY, and I will be ordering one for my own larger dog as well. You do have to work a bit with the dog to get the legs thru the leg holes to put on and off (so might not be ideal for dog with arthritic front end), but it offers WONDERFUL freedom of movement for walks, agility, nosework, etc. Very highly recommend!!
