When Penny's family brought home a baby, they might've been a tad worried about how the family dog would react to a new human in her home. But in reality, they had nothing to fear.
When Penny's little brother finally came home, Penny, a doting and loyal Shiba Inu, immediately fell in love with him - and took it upon herself to show him how to cuddle, among many other important life lessons.
Wherever her new baby brother goes, that's where Penny goes, too. If the little guy is being held by someone else, well, Penny tags along. She even whimpers when he starts to cry, according to Imgur user TrailerFanni, who posted the darling photo.
He only just arrived, but it seems like this little boy is already the luckiest little brother in the whole world.
