Watch out for the ferocious poochie dressed in their Shark Fins Pajama Pals Dog Costume! Almost as scary as JAWS....but much more amusing! Pajama pals costumes are definitely a notch above in the dog costume category. Made from a soft polyester-cotton fabric. A drawstring hoodie and Velcro closures allow for maximum comfort and an adjustable fit. A custom designed opening at the base of the neck fits a leash.
