Dog Hits Major Milestone in His Big Brother Duties Towards Baby Sister

An Instagram video shows how a dog and his baby sister’s bond grows stronger in her fourth month. Named Tommy, the Staffordshire Bull Terrier (aka Staffy) cannot stop wagging his tail around the little one. According to the video’s caption, the pooch was only “interested” in the toddler when she was born. But in the fourth month, Tommy expresses his excitement while playing and spending time with her. The pet parents celebrate it as a major “milestone.” “Words to describe Tommy’s 4th month as a big brother: tail-wagging,” the caption reads.

Dog reaches his ‘tail-wagging’ phase with baby sister

In the heart-melting dog video, the Staffy puts his tail-wagging skills on full display while playing with his baby sister. The clip begins with on-screen text that reads, “Month #4 of Tommy being the best brother.” It shows the toddler petting the dog, who sits beside her in an orange hoodie. Then, the post shows sweet moments between the two, highlighting the change in Tommy’s behavior around the baby.

“We really started to see Tommy enjoy his sister’s company more and more from this point. He went from being just interested in her to actually getting excited and wagging his tail when they interacted, which felt like such a big milestone for us,” the caption reads.

In the video, the Staffy gently approaches his baby sister every time. He sniffs and nudges her tiny palms while wagging his tail continuously. Furthermore, he keeps an eye on her whenever her parents are not beside her. From entertaining the baby to giving her toys, the big brother cannot contain his excitement around his sister.

Their sweet bond has caught the attention of many viewers. One user commented on the video, “So cute when he was rolling the toy towards her. I love seeing them together. He is the best big brother.” Many others praised the dog for being the perfect sibling to the little girl.
