Bought this for a ten week old chihuahua and it is big on him. X-Small was to small and this one is to big. it is of nice quality and looks really cute. puppy likes to chew on the little legs attached. everyone thought he looked cute in the picture. It is worth the money, and would bring you happiness.Got this for my 6 lbs yorkie, and it fits perfect. I love this on him, and the fact that it comes with stuffed little legs that is part of the costume, is a plus. He chases the "feet" on this thing while he is wearing it, in circles, so of course, that gets a lot of laugh from me. It looks to be well-made, and for such a small dog, just watch out that he doesn't use it for shredding. I will definitely order from this company again. More! more!The costume is cute but not as well made as I had expected....the fabric is cheaply sewn together. Too bad...This is just too cute. Gave it to a friend for her toy poodle - it's adorable.
