Very nice coat that covers quite well. Seems to be warm enough for my Boston Terrier. Rated to -20F however it's not a full cover suit so I wouldn't take the dog out below +25F anyway, or even under 32F without paw coverings of some sort (still looking for compatible shoes). I really like the ease in which this jacket goes on. Has one strap that goes between the front legs and up around the back and clips together and is adjustable. The back has a covered opening for the leash to attach to a harness underneath. Didn't try hooking it to a collar which would run the leash through the opening and higher up to the neck, I suppose that would work as long as it didn't put excessive stress on the opening given the indirect placement of a collar attachment. The back of the jacket has soft elastic straps that the back legs go through which run on the inner thigh to keep the back of jacket in place. The first jacket was just slightly too short so the straps rubbed uncomfortably against his skin and the back didn't quite seat properly over the butt. So I ordered a size up and it fits much better. The straps don't irritate now as they hang looser. They should just hang as a guide and not hold tightly and rub. Being that my Boston was in between sizes, the larger size coat was just slightly long but because the coat has a length cinching cord, I was able to draw it up as needed. This is one of three adjustment cinching cords on the coat. There is one at top of the should/base of neck and another on the pull-up hoodlike inner that you can cinch for better enclosure against wind and cold. But my favorite thing is you can option to pull this hood up and over the ears and then cinch it (being careful to not over tighten) to the proper fit so that it stays up and protects the ears! The cinching cords take a minute to get use to because there's no bulky plastic mechanism that you usually find on this sort of thing in which you pull the cord and push in the button to hold. So this is much better for comfort and streamline purposes. Instead there's a tiny plate with tapered slots that you pull cord through and guide to narrow end of slots to where it grips the cords. Pretty simple yet effective and frankly once you adjust them you should only have to readjust the one on the hood as needed for have the hood up or down. Otherwise once adjusted there's no need to readjust any of them. There were no problems with getting any urine on the coat when he goes to the bathroom given the design and fit. There is a snap behind the butt that you can either leave unsnapped or just unbutton when you see your dog needs to do a #2. Or you can snap the whole back up above, which will stay well out of the way for even the clumsiest of dogs. The jacket seems very well made and looks sharp as well. The 3m reflective material reflects brightly and is highly effective. Very happy with this coat!
