Pets rarely appear in paintings, photographs or other illustrations wearing much apart from a collar in the 19th and 20th centuries.
But fast forward to the 21st century and there is plenty of attire for pets that includes disguises to wear at parties and parades, especially at this time of year. “Fido” can become a superhero and “Kitty” a ballerina in a tutu.
The donning of pet costumes increasingly appeals to pet owners and spectators alike and has spread widely through social media.
According to one online source, Canine Journal, nearly half a billion dollars is spent in the U.S. each year on Halloween costumes for pets, and 20% of owners plan to dress their pets up in 2021, up from 18% in 2020 and 17% in 2019.
