There are 100+ pet holidays spread across the year — from National Pet Day (April 11) and National Dog Day (August 26) to month-long observances like Adopt a Cat Month (June). For pet-care pros, they're a ready-made content calendar: an easy reason to post a photo, send a report card, or run a small promotion. Here's the full month-by-month list.

Some dates shift year to year or vary by source (a few fall on "the second Saturday," etc.). Treat this as your planning calendar and confirm the exact 2026 date before you promote it.

How to use pet holidays in your business

Each of these is a low-effort reason to stay in front of clients:

• Post a themed photo. A National Dog Day before-and-after, or a Love Your Pet Day group shot — and caption cat posts with the right cat hashtags so new owners find them.
• Send a report card. Tie a photo recap to the day — owners love it and share it.
• Run a small offer. "Adopt a Shelter Dog Month — 10% off a new client's first week."
• Plan ahead. Add the big ones (National Pet Day, National Dog Day, the December holidays) to your calendar now so they don't sneak up on you.

You don't need to mark all 100. Pick six to eight that fit your clients and put them on repeat each year.
