Sometimes our pets make just as good babysitters as we do, and this cute black dog named Bosco is no exception. He has an infant human sister who crawls all over the house, and of course, there are places she’s not supposed to go. But in true baby fashion, those are the exact places she wants to explore!
In this clip, Bosco is lying right in front of a door that he knows the little one isn’t allowed to go into. The curious baby naturally wants to check it out and even tries to crawl over Bosco to get into the room. Bosco may look like he’s lazily napping, but one thing’s for sure: that baby isn’t getting into that off-limits room!
What a good caretaker Bosco is! He took the gentle parenting route and quietly told his baby sister no, or as his mom says in the video’s caption, “He said not today, missy!”
