Last month, Sisu, a stay dog, stole our hearts when he repeatedly tried to steal a purple plush unicorn from his local Dollar General store. To celebrate Sisu’s special bond with his furry best friend and in honor of National Unicorn Day, the Pedigree brand and Pedigree Foundation are releasing a limited-edition T-shirt. The adorable tie-dye T-shirt is now available for purchase on Pedigree Foundation’s DOGS RULE. online store for a limited time.

All proceeds from the shirt help dogs like Sisu find loving homes through shelter and rescue grants.

In addition to the shirts, the Pedigree brand and Dollar General are making a donation in celebration of Sisu to the Duplin County Animal Shelter and Lab Rescue LRCP, where Sisu is spending some time before finding his forever family.
