Meet Shelby Hennick, a 21-year-old veterinary technician living in California.
Hennick's grandmother, Dona, was hospitalized three days ago, after she had a reaction to one of the medications she was taking.
Hennick told BuzzFeed News that her mom had an idea to take Dona's dog, Patsy, in to see her. "I just happened to be passing my grandma's house when she called, so of course I was gonna do it," Hennick said.
Hennick wrapped Patsy in a blanket pretending she was a baby, and managed to sneak her into the hospital.
Hennick said her grandmother initially thought she had brought in her sister's baby. When she put Patsy down on Dona's lap, Dona was very surprised.
She tweeted about it, and said she had no idea it would get so much attention.
People thought it was really sweet.
A lot of people shared photos of when they did the same thing for their parents and grandparents, sometimes with the help of nurses.
"I was really happy we were able to pull it off, and I'm sure it made her day," Hennick said. She added that Dona was doing better, and went home from the hospital on Monday night.
