Princess Sophia is one of those big, not-so-easy-to-find-a-home-for dogs.
And recently, she got even bigger.
"We saw that she was that she was getting fat and round," Pena says.
She's having a baby.
But when it came to her precious cargo, Princess Sophia wasn't about to trust humans again. So she completely disappeared from the area.
Days later, someone heard that she was spotted with her babies in nearby Homestead, Florida.
Volunteers went there and started feeding the local dogs.
"As we were placing trays down, we heard the puppies crying," Pena recalls.
It was coming from under a house.
A moment later, Princess Sophia made an appearance.
