My guys have coats very similar to the custom made ones in the link.
Essentially the same design but with a fleece turtleneck that slips over the head, rather than a strap in the front. the material is a goretex type outside with polar fleece lining, and they were custom made by a seamstress friend of mine.
Dogs seem to like them..they get all excited when they see me take them out of the closet. I'm satisfied with the fit, and the dogs do seem warm enough in them
