Cover in the rest of its face and the sides of the cake with tan buttercream fur using a
small grass piping tip. Be mindful of what direction you pipe the fur in. I tried to pipe it in different directions to follow the natural flow of fur on a golden retriever's face and to give the cake a bit more dimension. This can take a bit of time, so be patient and give your hand breaks as you go. If you notice the heat from your hands is melting the frosting and changing its consistency, wrap the piping bag in a couple of layers of paper towel or a thin kitchen towel.
