Although miniature versions of West Highland White Terriers, or Westies, do not exist, the American Kennel Club categorizes full-size Westies as small dogs. AKC.com has a number of cute Westie puppy photos, as do breeder websites such as WestieWhispers.com.
The Westie is a Scottish terrier with a rough white coat and pointed ears. Westies weigh between 15 and 20 pounds when fully grown. The American Kennel Club and other breed clubs do not recognize "mini" or "teacup" versions of the breed. Westies are loyal, high-energy dogs known for being friendly and stubborn. These dogs typically live for 12 to 16 years and have litters of three to five puppies.
