Meet the Unbreakable Bond: Big Dog’s Heartwarming Tolerance for Little Brother’s Antics Steals Hearts
Dogs’ Secret Nighttime Antics: A Heartwarming Story of Brotherly Love
What Do Dogs Do at Night?
Have you ever wondered what your furry friends do when the lights go out? A recent Twitter post has shed some light on the secret nighttime antics of two large dogs, and it’s a heartwarming story of brotherly love.
A Gentle Giant
The video shows the “older brother” dog, Masao, remaining still while his “younger brother” Tsutomu pets his nose and eyes. Despite being teased, Masao doesn’t flinch, earning him over 11,000 likes on Twitter.
According to the owner, Masao is a timid dog who reacts sensitively to external stimuli, but he’s also very intelligent and understands human language. His sweet side is evident in the way he sleeps next to his owners during the day.

Meet the Brothers
Masao, a 4-year-old Bernese Mountain Dog, and Tsutomu, a 1-year-old St. Bernard, may not be related by blood, but they’re as close as brothers can be. Their owners chose human-sounding names for them, and they’ve grown to be inseparable.
Tsutomu, on the other hand, is a laid-back dog with a calm personality. He’s very curious and loves both humans and dogs, but his dependence on Masao can be a problem, according to the owner.
A Family of Dog Lovers
The owner, who initially didn’t like dogs, was won over by Masao’s cuteness. He and his spouse now live with both Masao and Tsutomu, and they’re grateful for the joy the dogs bring to their lives.
“We hadn’t planned on getting a second dog, but now we’re glad we did,” says the owner. “Tsutomu looks just like Masao when he was a puppy, and my husband and I fell in love at first sight.”
