Fur balls like a cat gets from licking their entire body clean where they swallow the fur because of their rough tongues (which is hard for me to imagine could happen to a dog because of their smooth tongues and that they don't groom their body usually other than paws and lower legs) or matted fur on the outside of their body? Either way a Pomeranian has lots of long thick fur and really should be brushed, at the very, very least, every couple of days.
Brush as much as you can then find a dry cat food with hairball control it might work and she might like it. Good luck.
maybe a little bit of fish oil put into the dogs food my help. Or I can suggest breaking a human soft gel fish oil tab in 1/2 & putting it straight down the dogs throat by putting the oil directly into a animal medicine syringe then administer it. This may be helpful.
