A Pomeranian is fairly easy to do, but never ever take it to a groomer unless they are an expert in this breed. I have seen many Pom's in the South clipped with a lion clip !!!!!!!! They should never ever be clipped, shaped by scissors yes, but never clipped.
The Pomeranian should look like a Pom Pom, all rounded.
If you e-mail me at spanishwaterdogs@supanet.com I will try and explain to you how it is done :d
