Great Little Coat
We have two little, male and female, non-related terrier mixes. Both are about 8 lbs., 15 in girth, and 12 in from neck to tail. Our female has some issues... car chaser and leash aggression... so we have been intending to get the Webmaster harness for better control; however, the current jackets that they have would not work with that kind of harness, so we purchased two of the Climate Changer jackets in XXS, Lichen green. The jackets fit perfectly and are easy to put on and take off. Their snug fit will be perfect under the harness (which we don't have yet). The tab of fleece under the zipper is very helpful for not catching their fur while you zip it up. And there is plenty of room for the little male, if you know what I mean. All in all, very happy... so much so that our daughter and son-in-law will be getting Climate Changers for their very large dogs to go under their harnesses, as well. My only complaint is that Ruff Wear charges the same price whether you by an XXS or XL. In all honesty, We probably would not have purchased two of them had we not been able to get them in the outlet.

perfect for my dog
This jacket fits my dog beautifully. She is medium size (40 lbs.) and muscular with a large chest and the medium size fit great. The weight of this jacket worked well for temperatures to 20F, but she did some shivering in this jacket when the temps dropped below 20F. Overall, I'm very pleased with this purchase.

Keeps my dog warm
I bought this for our Lab mix. He's around 60lbs and the medium fit him perfectly. He doesn't mind wearing it and the jacket looks great on him! Our other dog has one of these too, so now they match. :-)

Nice Jacket
I bought this jacket for our 3 year old boxer in both large and medium. I'm keeping the large. He's 25 or 26 inches at the shoulder, weighs about 70 or so pounds, with a girth of 31 1/2 inches and his back is about 22" long. I couldn't zip the medium. The large is a bit snug from the neck to the arm. This may not be the case for dogs that are not as deep chested as boxers. Like some of the other reviews noted, I too found that it rubs his fur off at the top of his arm when he is very active. I'm going to fix it because I'm very happy over all. He seems very comfortable in this jacket and that wasn't the case with others I've tried. We are in northern Ohio and I put this jacket on when we run errands and he waits in the car. As for warmth, I still avoid very cold or windy days. I like it for days above about 25 because the wind and cold can penetrate it. I especially like the coverage of his chest and underside and that he can still do his business without getting his jacket dirty. I wish they made a warmer version.

Climate changer
Great service at Altrec as usual. Dog jacket is excellent quality. Just my dog is between sizes, might have to return for the next size up. I plan to get another jacket from you guys as well.
