The tale of Lombard the dog may be the cuddliest tale (errr, tail) ever told.

Lombard's trainer, Hana Kim, documented one second from each day of Lombard's journey to become a guide dog — from puppyhood to his final days of formal preparation.

Ultimately, Lombard didn't become a guide dog. Instead, he's now pursuing a career as a therapy animal. But this pup's journey is still worth watching — especially if you're interested in crying happy tears.
