Exquisite quality, Maxbone is Lululemon for dogs! A small may have been a perfect fit, however I ordered up a size to a medium (my pup weighs 7.5 lbs fully grown, Maltipoo) I like for the jacket size and longer length to cover her behind for additional warmth and protection, medium provides that. I also appreciate the straps that allow you to cinch and secure the jacket around the front sides and back, as well as the snaps that cover her completely underneath. Aspen looks super stylish as she walks the streets of NYC ever few steps were stopped and complimented on how cute she looks in her jacket, last week while we were in Chicago we even had a lady come up to us and ask if we got Aspen’s jacket from Maxbone and I went on and on raving about how exceptional quality I’ve noticed with all of your products. Please please please restock the camel color need to order ASAP!
