Lhasa apso or toy pom?

There is no such thing as a "toy" Pomeranian. There are puppy mill terms like "toy" and "teacup" and "micro" and everything else which means that they are runts bred down from sickly dogs, don't follow the AKC standard, and should not be bred. It really depends on what you are looking for in a dog. Pomeranians tend to be a little on the yappy side. Both have a lot of hair to keep up with, but the Lhasa is pretty easy if kept in a "puppy clip" with short hair. It's your decision. Find a good breeder...not pet stores, backyard breeders who let their pets breed, or pet stores!
