Monty and Rosie were both born in the same litter last year. However, when they were a few weeks old they took different paths as Monty has been adopted by different family. But since they live a few miles away from each other, after almost a year the fate brought them together, once again. And the moment they met would definitely melt even the coldest heart.

The two cockapoos were on a walk when Monty spotted his sister and immediately recognize her, even they got separated when they were only pups. And while dogs usually sniff each other when meet, Rosie and Monty's reunion instantly turned into a big, heartwarming hug.

"It was so lovely, they both just jumped up and hugged each other," Susan Killip, Rosie's mom, told The Dodo. "It was amazing they remembered each other after 10 months of not seeing each other."

The heart-melting scene went viral after Libby Pincher from Bishop Auckland, England, shared on Twitter a text she received from her dad about the two pups reunion. "So, Dave was out walking his dog, and there was a couple walking towards him with a white version of his dog," the text reads. "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."
