You could take this dog anywhere and no one would know.Meysi is a three-month-old Terrier from Poland who only weighed 1.58 ounces at birth.  Her owner did't think Meysi would make it and it took all her strength to keep Meysi going. She had to feed the mini pooch every half hour.  Meysi weighs 3.25 ounces now, but her veterinarian doesn't expect her to grow much more.  Imagine the fun you could have with this tiny pooter.  You could dress her up as a mouse and scare the crap out of people.  Put her in a cockroach outfit, oh the laughs!  She has to meet the required age limit of one-year to be considered for the title of World's Smallest Dog by the Guinness Book of World Records.  She will be vying for the title with Beyonce, a dachshund mix who was so tiny at birth she fit in a spoon.
