You’re scrolling through your socials when you wonder, “Why are there so many pictures of chihuahuas, and why do I suddenly have the inexplicable urge to eat tacos?” Then it hits you. It’s International Chihuahua Appreciation Day—and you missed it!

Pet holidays are a great opportunity for veterinary practices to become part of the conversation and connect with pet owners on social, as well as an opportunity to remind clients about important pet health issues. Yet with so many pet holidays, it can be nearly impossible to keep track of them all. To help with that, here is our annual list of upcoming pet holidays to bookmark for easy reference through 2021 to stay competitive with other practices on social.

Since the word “holidays” denotes fun, we also included some other favorite holidays. Somehow, we just know your clients will appreciate a reminder about National Donut Day or National Pizza Day.
