Chance Morgan saw his dog Bleu on Thursday for the first time since the husky went missing five years ago.
Chance, 16, has a form of autism, and his dog was his best friend.
"Excited, it just overwhelms me, just amazed, just definitely amazed," Chance said.
Bleu had been put up for adoption earlier this week by a family in Macclenny who had taken the stray dog in. During a checkup, a veterinarian discovered the dog had an embedded microchip and learned Bleu was registered to Chance's family in Lake City.
"I am absolutely amazed," Chance's mom, Tracie Morgan, said. "When he went missing, we went horseback looking for him, we went by four wheeler, we went by truck."
