Teacup Yorkies are a miniature version of the Yorkshire Terrier breed. They typically weigh under 4 pounds when fully grown. While the term "teacup" is commonly used to describe these tiny dogs, it is not an official size recognized by the American Kennel Club (AKC).

Teacup Yorkies have the same playful, loving, and energetic personality website as regular Yorkies. They are affectionate towards their owners but can be cautious around strangers. Proper socialization is important to prevent potential behavioral issues.

However, there are significant health concerns associated with teacup Yorkies due to their extremely small size. They are prone to conditions like hypoglycemia, heart disease, and eye problems. Teacup Yorkies require constant monitoring, frequent feedings, and specialized veterinary care.

Reputable breeders do not intentionally produce teacup Yorkies, as it involves breeding the smallest runts of a litter. Puppies advertised as "teacup" are often simply the smallest of a normal litter and are at higher risk for health problems.

Before adopting a teacup Yorkie, prospective owners must be prepared to provide the necessary care and attention required by these tiny dogs. Potential adopters should carefully research the health risks and consult with veterinarians experienced in treating miniature breeds.
