A rescue dog with an adorably crooked smile that warmed the Internet's hearts has passed away.
The Humane Society announced Wednesday that Billy the chihuahua died unexpectedly over the holidays. Adam Parascandola, Billy's rescuer and later owner, shared the news in a tearful video that will touch anyone who has ever loved an animal.
Billy sparkled in the web fame spotlight after the story of his rescue went viral last December, accumulating more than 600,000 views on YouTube. The tiny dog grew up at a North Carolina puppy mill and dealt with many health problems -- including missing part of his lower jaw -- as a result of living in a cage without proper medical attention for years.
Parascandola hopes that Billy's legacy of bringing attention to the dogs still suffering in puppy mills will live on.
