Jacob had lost his dog, Tucker, and he was looking all over for him, posting messages and driving around for hours.

Tucker had been found by a loving family who already had a dog named Barney, they were in the process of giving Tucker a flea bath because he was covered in fleas.

They did not know Tucker’s name, though, so they called him “Larry,” which seemed to suit him just fine.
