Ana Carolina Lima and her fiancé from Brazil made one puppy's life happier a few months ago. This puppy, named Luna, was rescued from the street by Anna and her fiancé, and they have adopted him. They adore her, and Luna cheers them up every day. Recently, during a visit to Anna's grandmother's home, Luna found one more reason to smile. 

It didn't take very long for Luna to adapt to her new environment, so Anna felt comfortable enough to go out and leave the dog with her grandmother. And Lima's grandmother felt comfortable enough to lie down for a nap.

"As usual, she put her dentures under the pillow so as not to lose them," Lima said.

Luna, who was closely watching what was happening around, clearly saw it as a good opportunity.

When Ana’s grandma woke up from her nap, her dentures were gone.

"She was pretty desperate that she couldn't find her dentures. She and my mom searched everywhere. They searched for hours." Lima explained.

When she got home and found out about missing dentures, her first thought was to check if her dog had something to do with that. And the dog he was oddly quiet and hiding. It turned out he had its own reasons:

"I found Luna sitting in the armchair with Grandma's teeth in her mouth, She didn't want to give them back!" Lima says laughing.

Curious Luna was caught in act, but she didn’t show any signs of regret. In fact, she found all this fun.

After some wiggling and pulling, Lima was able to take the denture from the dog, and, luckily, they were not damaged. And with the grandma’s teeth gone, Luna recovered her former winning smile.

Of course, no one was mad at Luna for her little stunt. In fact, their reaction was completely opposite.

"We all laughed a lot!" Lima said. "We all love animals."
