If you don't have skills to draw dog's hair yet, it is quite possible to replace it with dressy clothes, as shown in this "Dachshund" tutorial.
1. For this exercise you will need: paper, graphite pencil, black marker, colored pencils.
2. Using graphite pencil, draw a dachshund similar to that one in the example below.
3. Using black marker, outline the sketch and decorate the dachshund's clothes with various lines (thin and thick, curves, zigzag).
4. Color in your drawing with pencils.
