National Dress Up Your Pet Day (yes, such a day exists!) has been celebrated every January 14 since the year 2009. The day was created by Colleen Paige — celebrity pet lifestyle expert and animal behaviorist — as a way for pet lovers to show off their beloved pets’ fashion sense.
According to the Royal Society for the Prevention of Cruelty to Animals (RSPCA), dressing up pets began centuries ago — and it’s for practical purposes! Thin, old, furless, or sick animals wore specially designed coats and shoes to protect them from rain and cold weather. Similarly, animals diagnosed with arthritis or hip dysplasia donned therapy jackets to ease their aches and pains. (Read: These Online Shops Make the Cutest ‘Barkday’ Cakes for Your Dogs)
But what about dressing up your furry four-legged friends with cute outfits for a quick photoshoot, or for special occasions such as Halloween or Christmas? The Animal Humane Society has a number of safety guidelines for that!
Among the tips are these: Make sure the costume is safe, comfortable, and does not limit movement; it is made of non-toxic materials; and has no small, dangling accessories that can get chewed and swallowed. (Read: Prayers of St. Francis of Assisi for Beloved Animals)
