It's National Dog Day, and to mark the occasion, Universal released the trailer for "A Dog's Purpose."

We didn't think a trailer could make us croon "awwwww, so cute" and also make us cry all the tears at once. Well done, "A Dog's Purpose."

The movie is based on the bestselling novel by W. Bruce Cameron and follows a dog (voiced by Josh Gad) who's reincarnated as different pups over and over again. He starts out as Bailey, the loving companion of a boy named Ethan. He's by Ethan's side as the boy grows up into a young man, until finally Bailey breathes his last.

From there Bailey becomes other dogs: Ellie, Toby, Bear, Buddy. Eventually, he winds up with Dennis Quaid, who turns out to be a familiar face from the past.

"If I can get you licking and loving, I have my purpose," Bailey says. (Sob!)

"A Dog's Life" opens in theaters January 27, 2017.
