The phrase refers to attire designed for animals, primarily dogs, to be worn during the Halloween season. These outfits typically consist of materials that allow for the animal’s four limbs to be accommodated comfortably, and range from simple decorative accessories to full-body representations of characters or objects.
The increasing popularity of dressing pets for festive occasions stems from a desire to include animal companions in family celebrations. This practice offers a means of expressing creativity and affection for pets, and can also provide entertainment for observers. The tradition reflects a broader trend of anthropomorphizing animals and integrating them further into human social activities.
