Recently, a woman named Libby Pincher shared an adorable moment a dog embraced its sibling in a heartwarming hug on Twitter. The post quickly went viral with more than 900k retweets and almost 200k retweets.

The two dogs, named Monty and Rosie, were born to the same litter last June. According to their owners Susan Killip, right from the start they were extra close. “There were six of them, but Monty and Rosie were always together,” Killip told The Dodo.

Sadly, the pair had to be apart when Killip’s friends from a nearby village adopted Monty and brought him home. The pups lost touch and hadn’t seen each other since Monty went to his new home.

Even though they hadn’t seen each other since they were puppies, they still recognized each other immediately. They ran over to each other and hugged each other in the happinest and sweetest doggy hug.

“It was so lovely, they both just jumped up and hugged each other,” Susan said. “It was amazing they remembered each other after 10 months of not seeing each other.”

Pincher’s dad described the adorable encounter and sent her all photos. “So, Dave was out walking his dog, and there was a couple walking towards him with a white version of his dog. Turns out they are brother and sister from the same litter. But instead of just playing like they do with other dogs, look at this.”

There’s some debate as to whether Monty and Rosie were brother and sister, or they were just excited to see another dog in the park. But either way, we and Twitter users love the touching reunion and would like to believe that the two pups really did remember each other.

We are happy to know that the two dogs’ parents will make sure they see each other regularly. “We will keep in touch,” Killip said. “It’s a bit difficult at the moment, but after this is all over, we’ll be having doggy walkies together.”

What a sweet story! We never expected a normal walk for two dogs would become a surprise family reunion.
