A white teacup Pomeranian is a very small Pomeranian that is white in color. A regular Pomeranian is expected to mature at 3 to 7 pounds. A teacup dog is one that is expected to weigh only 3 to 4 pounds when fully grown.
Teacup dogs have been selectively bred down in size by breeders interested in creating very small dogs. These extremely small dogs require special care and attention due to their size. They are easily injured if dropped or stepped on; a fall off a couch can be fatal. They are not recommended for households with children or normal-sized dogs.
