Yorkshire Terriers, better known as Yorkies, are popular small dogs used primarily for companionship. According to American Kennel Club (AKC) guidelines, Yorkies must weigh between four and seven pounds. Yorkies weighing less than four pounds are called "Teacup Yorkies," but they are not a distinct breed recognized by the AKC. According to the Yorkshire Terrier Club of America, such small dogs tend to be more susceptible to illnesses and inherited disorders, so buyers should take special care about where they get a Teacup Yorkie.
