Tinkerbell - the world's tiniest pooch!

Tinkerbell, a German Pomeranian, is the runt of her litter, weighing only 12.75 ounces. Despite being pushed out by her siblings, she is healthy but unsteady due to her size. If she remains small, she could become the world's smallest dog, surpassing the current record holder, a Yorkshire Terrier. Due to her size, she cannot safely play with other dogs, so she will move to a new home in North Wales where she will have a suitable playmate.
