For your dogs to participate in the wearing of the green for St. Patrick's Day.

Originally, the color associated with Saint Patrick was blue. Over the years the colour green and its association with Saint Patrick's day grew. Green ribbons and shamrocks were worn in celebration of St Patrick's Day as early as the 17th century. Saint Patrick is said to have used the shamrock, a three-leaved plant, to explain the Holy Trinity to the pagan Irish, and the wearing and display of shamrocks and shamrock-inspired designs have become a ubiquitous feature of the day. In the 1798 rebellion, to make a political statement, Irish soldiers wore full green uniforms on March 17th in hopes of catching public attention. The phrase "the wearing of the green", meaning to wear a shamrock on one's clothing, derives from a song of the same name.
