There are a few Pomeranian types always available for sale or in rescues, it looks. The domestic dog has incredibly flexible genes, and some types are proof of this. The original Pomeranian is probably extinct. They were sturdy sled-pullers and sheephers. Two centuries ago, they were about thirty pounds. When they went to England, the trend of breeding them smaller and smaller began. There are now toy dogs, teacup Pomeranians and exotic puppies today on both sides of the Atlantic.
The only thing that makes exotic Pomeranian puppies different from standard puppies is their color. That's it. If you get an exotic dog, be prepared for many know-it-alls to say, "That's not a real Pomeranian because the color is wrong." If you want to show your dogs, then exotic types are not for you, as they may be disqualified, even if you can prove that your exotic Pomeranian puppies are all purebred.
Exotic Pomeranian puppies will still be built like standard puppies, no matter what their coat color. Since the Humane League of the United States says that one quarter of all abandoned pets are purebreds, the chances are good that your suspected exotic Pomeranian puppy is a purebred. This will help you determine what the strengths and weaknesses of your potential puppy are. You also will be better prepared for medical problems later on.
Exotic Pomeranians will most likely be abandoned due to no fault of their own. Due to their small size, they (like most toy dogs) are difficult to housetrain. Tiny bladders mean they can not hold that much. Some have been successful in training exotic dogs to use a litter box. Their coats shed a lot, and molt twice a year. At four to five months of age, exotic Pomeranian puppies can look quite scraggly. These coats need daily grooming, or else they get unsanitary quickly.
Some puppies come in blue, parti-color (some patches of solid color on a mostly white body), chocolate (a dark brown), beaver (another shade of brown), lavender (a shade of light gray) and blue merle (must be seen to be believed). With the exception of blue merle, none of these colors are dramatic enough to catch the average person's attention. And yet, exotic Pomeranian puppies cost many hundred of dollars, even from responsible breeders.
Why do people care what color a Pomeranian is? Because some colors are fashionable, and some are not. Some people want to have a "special edition" that is hard to get and show that off. But exotic puppies act like standard Pomeranians. And they are increasingly becoming more fragile and less healthy with each passing color fad. There seems to be more emphasis on color and small size rather than health for these dogs. Pomeranians are thought to have the weakest teeth in the dog world.
