Yes. Simply unzip the abdominal zippers (some styles have zippers at the bottom of the sleeves, if so unzip those). Slip the garment over the dogs head (like a turtleneck), slide the front legs through the sleeves. Then slide the back legs through the sleeves and zip the abdominal zipper (and zip all 4 sleeves, if applicable). Pull the zipper flap material across the zipper to prevent catching any hair. You are done!
