Dressing up your dog on Halloween or pretty much any other day is fun. Friggin weird, but fun. With this Tarantula Dog Costume, you get to scare your neighbors and anyone who comes across your dog at night. It will be fun to watch them run away screaming. In poor lighting, your dog looks like a real massive spider running around. I just screamed myself! The chest, neck, and head are adjustable so that the costume can fit different sized (the smaller breeds) dogs. Those sparkling eyes and claws make it even scarier.
