The term "smooth coat" refers to a specific type or variety of dog breed that has a short, smooth-textured coat. This means that their fur is not rough or wiry in texture but rather lies flat against their body with no undercoat. Smooth coats are known for being easy to groom and maintain due to the lack of matting or tangling of their hair. Some popular breeds with smooth coats include the Bulldog, French Bulldog, Boston Terrier, and Pug among others.
