The palm sized puppy who stole our hearts last month is growing up.
Angel -- the Yorkie -- who could be the world's smallest dog.
At five weeks, angel weighed less than half a pound.
She was so tiny; her owner had to feed her by dropper.
Now, four months old, she weighs a whopping "one-pound" and her vet says she's a healthy happy pup.
To qualify as the worlds smallest, a dog has to be one-year old.
The measurement to beat is nine and a half centimeters tall.
Angel was about 5-centimeters at birth -- that's shorter than a can of soup.
