When Wahl launched a new line of dog shampoos, we decided to use it on animals that could use it most—shelter pets. The Wahl Dirty Dogs Contest is now an annual event with hundreds of animal shelters receiving Wahl grooming supplies. Those shelters submit before and after photos of rescue dogs along with their stories. The public then votes on the top 10 makeovers for a chance to earn money for deserving shelters. The campaign garners national press, great social engagement and the respect of retailers and consumers alike.
