Muddy Dog Day is celebrated on the last Saturday of October, with this year's observance falling on October 25. The holiday aims to bring joy to pet owners, particularly in the wake of COVID-19 lockdowns in the United Kingdom. It encourages dog owners to share photos of their pets playing in the mud, reflecting the fun and carefree spirit of the day. Jo Milnes, the founder of Distinctive Pets, initiated this celebration to promote engagement among pet owners and their dogs, regardless of breed, age, or gender. The event fosters a sense of community among dog lovers, highlighting the joy that pets bring to their owners' lives.
