March is packed with meaningful pet health observances and feel-good holidays that make it easy for veterinary clinics to educate clients, promote preventive care, and keep appointment calendars full before the busy spring season begins.

From safety awareness to parasite prevention and adorable puppy content, this month offers natural opportunities to connect with pet owners in ways that build trust — not just transactions.

Here are the top March marketing opportunities veterinary clinics can leverage right now.
