Smallest dog (height)

This tiny dog may be the ultimate pocket accessory. Milly, a female Chihuahua, stands a mere 3.8 inches tall. When Milly was born in 2011, she was so tiny that she was fed with an eyedropper, according to the Daily Mail. Milly may not be tall, but she's got plenty of cuteness.
