This Bullmastiff and His Human Baby Bro Are BFFs, and Their Photos Will Melt Your Heart

A surefire way to boost your mood is to look at cute pictures of dogs and babies, and the special bond between this bullmastiff and his newborn baby brother will send your happiness into overdrive. Bonnie Michalek and her husband got an adorable bullmastiff named Brutus in 2016. While Bonnie calls Brutus her "first baby," she gave birth to her first human baby, a son named Kayden, just 11 weeks ago. Being around a new family member has been no problem for Brutus — in fact, he has such a sweet, gentle relationship with Kayden that he acts like another protective parent.

"Brutus completely bypassed my husband to meet Kayden. He immediately wanted to give him kisses and snuggle up to him," Bonnie told The Dodo. Brutus even has his "own" Instagram account, Captain Brutus, dedicated to sharing photos of him and Kayden around the house. They cuddle together, sit on the couch together, and nap together. Brutus even has his favorite toy, a fluffy yellow plush, that he brings to Kayden to console the baby when he's crying!

The relationship is too freaking cute to handle, and we can imagine just how special Kayden's bond with the pup will continue to be as he gets older. Ahead, see some of the sweetest moments that have been captured between the two, and cue the "awww"s.
