But when Leia realized that Snyder's dad wasn't coming home, she grew deeply upset and showed just how much she'd grown to love him. She went in front of the door, put on the saddest face, and just wait there, for an hour, for her human to return home. Katie's mother snapped a few pictures of Leia and sent them to her daughter.

"When she sent me that picture, I immediately burst into tears," Katie said. "It was so overwhelming. I was able to see how much [Leia] truly loved my dad and that she was missing him."

Until that moment, no one realized just how attached to her grandpa Leia had become. Snyder decided since the pup loved her dad so much, she would let her stay with him forever.

Happily, Snyder's dad was okay and returned home the next day to an overjoyed Leia. "He is her human now," Snyder said in an interview.
