There is some debate over whether or not puppies remember their litter mates after they are all adopted into different families.
Really, there's no way to know for sure, though some researchers believe that if the puppies spend at least 16 weeks with their siblings, then they are more likely to remember them.
Of course, we humans tend to read a lot of emotion and intent behind our doggos' actions in general.
You see, when someone they knew was out walking their curly, black cockapoo, they crossed paths with another dog that was almost identical, save that the fur was white.
Expecting a greeting sniff and maybe a short play, the humans were instead surprised to see the two dogs rise up and wrap their arms around one another.
After chatting, the humans realized that the dogs, Monty and Rosie, were actually brother and sister.
Rosie's human, Susan Killip, told The Dodo that the litter had six puppies, but these two were particularly close.
