Size, or rather, lack of it, matters when it comes to teacup puppies. Not recognized as a distinct breed, these cutey-pies are bred smaller than toy breed official standards. Unofficially, teacup pups must measure less than 17 inches when full grown.
Shih tzus, which translates in Chinese to “mini lion," in deference to their lion-like appearance, are snugly built, flat-nosed, teacup pups that stand about 8 to 11 inches tall and weigh 9 to 16 pounds when full grown. Shih tzus' hair grows long and straight, past the feet, but sheds very little, making them a good choice for those who deal with pet allergies, or simply dislike cleaning up hair. With a lifespan of 11 to 16 years, these funky little teacups are known to be playful companions, delighting everyone around them with their cheerful attitudes.
At an average 12 inches in length and 6 pounds in weight, teacup Chihuahuas are considered by many to be the perfect “purse dogs.” However, these intelligent, alert, confident purse puppies are not to be messed with, as they are capable of displaying a disarming terrier-like fierceness when provoked. Some teacup Chihuahuas are short-haired and some are long-haired, but they all detest the cold, appreciate fashionable outerwear and enjoy long lifetimes of 14 to 18 years.
Bold, curious and ready for anything, teacup Yorkies weigh an average of 3 to 7 pounds and measure less than 17 inches. They have long, flowing coats and require professional grooming to look their best. Bred as ratters (chasing vermin in factories), these feisty little giants have a lifespan of 14 to 16 years.
Known for their alert, fox-like demeanor, busy, bold Pomeranians make perfect pet companions, always up for a game or adventure with their human friends. They are big-time barkers around strangers, and are sometimes unfriendly towards other dogs on their home turf. Ranging in size from 7 to 12 inches and weighing between 3 to 7 pounds, these heavily plumed, long-coated teacup pups live for 12 to 16 years.
