National Dress Up Your Pet Day was founded in 2009 and is sponsored by the Animal Miracle Network
But it's always important to remember that sometimes the clothes don't make the pet.
"It's not...a day to disrespect our pets with uncomfortable, vulgar and/or seasonally inappropriate costumes for the sake of a laugh or photo shoot" says pet expert Colleen Paige.
Have fun with your pets by dressing them in cute outfits and safe costumes - but keep your pet's comfort level in mind when involving him/her in this fun novelty day. Make sure that your pet can see and hear properly and that they aren't wearing something that might overheat them or incorporate any parts that they may chew off and swallow.
