Dog Therapy Appreciation Day is observed worldwide every April 11 to acknowledge and appreciate the significant contributions of therapy dogs and their handlers. This day highlights canine-assisted therapy, which helps improve patients' emotional, social, and cognitive functioning in various settings, such as hospitals, nursing homes, and rehabilitation facilities. The celebration was launched in 2019 and is supported by animal-assisted therapy organizations and countless patients who benefit from these interactions. The history of dog therapy dates back to the late 19th century, with notable figures like Florence Nightingale and Sigmund Freud recognizing the positive impact of pets on recovery and communication. Organizations like Therapy Dogs International, founded in 1976, play a crucial role in certifying therapy dogs, which must meet specific behavioral criteria. Participants can engage in the celebration by learning about animal-assisted therapy, volunteering, or sharing their experiences on social media using the hashtag #DogTherapyAppreciationDay.
