86-year-old dad becomes TikTok sensation after receiving Pomeranian puppy gift from daughter.

A man named John, 86, and his Pomeranian pup, Dolly, have gone viral on TikTok as viewers get a sneak peek at their daily life together. John's daughter, Katie, started documenting the interactions between her father and Dolly and sharing videos on TikTok under the account @_dadanddolly. Katie moved her dad John into the apartment next door to her about two-and-a-half years ago, and living near her father helped them form "a very close bond." Dolly helps keep John active, but doesn't push him too far, and she challenges his memory in a positive way.
