We ordered this in the fall for my “apple shaped”, 30 pound cockapoo in a size small (she has a 24 inch chest). Dog clothes are hard to fit my dogs who are completely different shapes and sizes but this fit my cockapoo well. It is fitted but not too tight and I am thankful for the zipper on the back! I wish more dog companies would make clothes that were step in with zippered backs for dogs who are fussy about things going over their heads (and many of my dogs have had this issue in the past). We had an issue with the zipper and RuffWear sent me a new one for free under their warranty program. My only “complaint” is I would love to see prettier colors/prints for both my dogs but especially my girl. Most of the clothing colors are dark, boyish, and not very cute (I get it, it’s an outdoorsy company and that’s not their selling point lol). The quality is top tier but more variety with colors and designs would be great!
