A few months back I bought a pomeranian at a pet shop for $600. Right now she's 6 months old, and her fur never really started to grow. Every other pom puppy I've seen since has had fluffy legs, and a full tail. My dog has none of this. Her hair isn't long at all, and I was wondering if this is normal in pomeranians. Or could it be possible that she's not a purebred. Her fur hasn't changed yet, she's had short hair since she's been a pup.
