If your dog is willing and will let you dress it up or put makeup on it, then this Dark Knight Joker dog costume could be something to consider this Halloween! If you’re not too willing to spend so much money for a Joker costume for yourself, then why not dress up your dog in it instead? If you want to go the homemade route, you can always go to a professional dog groomer and have them do up your dog in this manner–with the lined eyes and red mouth. The dog costume doesn’t require so much work and the makeup is optional. Just make sure that your dog is okay with dressing up or putting on makeup of any sort. The safety of your dog is first and foremost!
