We all love rooting for the underdog, and our Underdog Costume for Pets is your dog's chance to be a hero! Your pet already loves getting praise, so he or she will be thrilled when your friends and family root them on in this adorable one piece suit that comes with an attached cape. The red shirt proudly displays a white U so that everyone will be able to recognize your super pooch from the second he flies into the room. The bright royal blue cape is attached to it and will make your dog's superhero status complete. Your pet may not be able to fly or punch through walls, but he's super to you. So dress him up in this adorable dog's superhero Underdog costume this Halloween.
