National Therapy Animal Day is observed worldwide every April 30 to recognize the vital role of therapy animals in providing comfort and healing to individuals in need. Established by Pet Partners, a nonprofit organization based in Washington, this day honors the contributions of therapy dogs and other animals in improving emotional, social, and cognitive functioning for various conditions, including anxiety, PTSD, and chronic illnesses. Celebrations may include volunteering as a therapy animal team in settings such as hospitals and schools or donating to animal-assisted therapy nonprofits. The day encourages sharing positive experiences with therapy animals and promoting awareness through social media using the hashtag #NationalTherapyAnimalDay. Therapy animals, which can include dogs, cats, rabbits, and even birds, must meet specific criteria, such as being friendly and healthy, to participate in animal-assisted therapy.
