International Blind Dog Day is observed worldwide every August 23. Established in 2017 by Sarah Horne, a dog-lover from Cambridgeshire, the day aims to bring together owners of blind and visually-impaired dogs and encourage the adoption of disabled pets. It highlights the challenges and misconceptions surrounding blind dogs, emphasizing that these animals can lead happy lives with proper care. Typical customs include treating blind dogs to new toys or treats and sharing their pictures on social media using the hashtag #InternationalBlindDogDay. Additionally, individuals are encouraged to consider adopting a disabled pet or donating to organizations that support blind dogs, such as the Blind Dog Rescue Alliance.
