Small and adorable though they may be, the Pomeranian is descended from larger working spitz-type dogs. While they have been companions and lap dogs for many generations, and have steadily decreased in size, Poms still have a working dog's bravery and some of the spitz's independent spirit. Therefore, to train your Pomeranian puppy to do fun tricks that you will both enjoy, find ways to motivate her that will appeal to her own interests.
Always have fun with your Ppomeranian puppy. Be reasonable in your expectations, and keep in mind that your pomeranian's ability to think for herself is part of what gives her such a wonderful personality. If your Pom isn't in the mood for a particular trick, just try another one or try another time.
