If there are other dogs in your home, treat them also, even if you don't see lice on them. Otherwise, the dogs may continuously re-infect each other because they are on different treatment schedules.
Bayer Advantage II Flea & Lice Treatment for Small Dogs
It does sound like Koda has lice; the best course of treatment is to use a shampoo specifically for lice which you can get from your Veterinarian or pet store. The shampoo kills the adults but the eggs are not affected, so daily washing is required for usually two weeks; please read the specific instructions carefully for the product that you purchase also thoroughly clean your home and your dog’s bed (may need to be thrown out and replaced).

Pediculosis is also known as lice. Lice are small insects that can live on your dog’s skin and hair coat. These parasites are flattened and do not have any wings. Once they find a host, they do not want to leave and will spend the extent of their life on him. There are several types of lice; those that suck blood and those that do not, preferring to chew on skin. The presence of lice on your dog can cause skin irritation, itchiness and in severe cases anemia. Without treatment, lice can spread to the entirety of your dog’s body.
