This dog Halloween costume can be played as an alligator or a crocodile. In our case, we went with the crocodile to complete our perfect Peter Pan/Hook theme! Our 16 lb. Shih Tzu looked adorable, and it didn't seem to bother him as much as other costumes usually do. The Velcro straps helped it stay in place, and he was still able to go to the bathroom normally. The only thing that would've made it even better, that I just thought of would be a ticking clock around his neck. Neck 13"-17" Chest 20"-25" Length 14
