I bought an XX large. My Bugg (Boston/Pug mix) is 23lbs and on the longer side. I struggle finding sweaters long enough to cover her bare belly. This fit perfect! Not too snug but not too loose. There is a fleece layer under the sweater so this is my go to in colder weather (40-50 deg F... I'm in So Cali after all). Great product!Great hoodie thick and well made only minor issue is that there is no hole for the leash latch.Absolutely the cutest! As you can see the gray of the trim on hoodie compliments his salt and pepper muzzle. Notice in the back ground his little brother Gizmo, looking enviously on Mr. Pugs aka MGP.... who looks very dapper in his new sweater! Would definitely recommend for any pup looking for a pick me up!I had to return the first sweater because it was a bit big, but liked it so much & it was easy enough to return & get a smaller size. *runs on the larger size*I do like the snap buttons and the thickness lets me know it’s keeping Vyvyan nice & warm!This sweater is very fashionable and I love the look of it! It is plush, warm and comfortable for my fussy dog that usually does not like to wear shirts or sweaters but due to the major back surgery he had, must be kept warm. This jacket delivers on warmth and very pleasing to the eyes. I will definitely order another sweater in another color.Runs very small! I have an 11 pound yorkie and the medium is tight on him! It is good quality for the price though. The inside lining is a soft wool material, good for cold days and nights.Good quality, fit well. Love itI’m happy and my dog is happy. Fits him good ?Muy bonito sin embargo aunque es talla extra larga. Es para perro pequeño yo tengo un labrador así que obvio no le quedo talvez habría que aclarar que estás tallas son para razas pequeñasLove this - a little large for my mini daschund - good quality and will be perfectMuy pequeña o mi cachorro creesio muy rapido
