A pair of shelter puppies born to different moms have struck up a unique bond of cuddles and companionship while being nursed to full health as seen in a recent TikTok video.

Friendship might be an entirely human concept, but research has highlighted the importance of dogs enjoying regular socialization with other canines.

A study published last year in the journal Evolution, Medicine and Public Health saw researchers pore over data collected from 21,410 dogs and their owners to identify the key factors that affected canine health. While household income ranked highly, the factor most commonly linked with better health outcomes was more social companionship with humans and other dogs.

That's what makes the blossoming friendship between the imaginatively named puppy pair of Orrin Elouan and Herbert Ren at Roadogs Southern California Dog Rescue that bit more special.

"Roadogs is known for giving our dogs fun, double barrel names," Nikki Carvey, the founder of Roadogs, told Newsweek. "I'm a Brit and it started with me wanting to give them old fashioned and mythical names and escalated from there!"

While their new names are special enough, what's really magical is the way the two pups have hit it off, providing each other with some much needed comfort and support after a bumpy start to life.

"Orrin Elouan was a singleton pup who was surrendered at five days old," Carvey said. "He has a cleft palate and required special care, so our awesome foster Melanie, who tube fed him every two hours around the clock."

While Orrin, who is the brown-coated puppy in the video, has flourished alongside Herbet, the darker of the two dogs, who is also being fostered by Melanie, with updates regularly posted to her Instagram @nyx_persephone_friends.

"Herbert Ren arrived in Road Dogs care at 0.9lbs at 7 weeks of age," Carvey said. "He was tiny, malnourished, bug eyed, and could barely stand. So Melanie gave him extra special care too. He wasn't able to eat well on his own, so his food was puréed and made into a consistency that he was able to eat."

That care has proven crucial to getting the two pups through a difficult time in their young lives. It also brought them together and provided both dogs with some additional companionship.

"These two connected pretty fast. Orrin was in better shape than Herbert when they were first introduced, he was trying to engage Herbert with play," Carvey said. "Herbert was a little stand-offish at first, barking at Orrin to set boundaries, but the next thing you know, these two were snuggling together, playing together, and exploring together."

With no mother or litter mates to call on, being together and around other foster dogs has proven crucial to their overall development. "They are learning to be puppies through experience with another pup similar in age," Carvey said. "It couldn't get any cuter."

In some ways, it's a friendship that has also provided them with some semblance of the secure base every young pup gets from their mom. Evidence of that can be found in the clip posted to TikTok on June 3 by Roadogs showing the pair snuggled up together.

As the caption puts it, the clip is "just two rescued puppies finally feeling safe." That sense of safety has helped both dogs to gain confidence, with their natural personalities shining through as a result.

"Orrin is very active, opinionated, and vocal. He seriously talks to you as if you were having a conversation with him. He loves to play with his toys. He is often tossing his toys around, growling at them, barking at them. He likes to run around as much as possible to get his energy out," Carvey said.

She added: "Herbert is a bit calmer, quieter, and LOVES to be snuggled by his human. He also likes to explore, but is a little more cautious, at first, when learning something new. Orrin was also raised with a foster kitten and they used to play together, so Orrin loves to chase and play with the household kitties as well."

The two puppies are due to be separate soon, but it's for the best possible reason. "Orrin has already been adopted and is going to his forever home this weekend," Carvey said.

The hope now is that Herbert will find his forever home soon and someone else to snuggle up to. "Herbert Ren would do well in a home where he gets lots of attention from his human," Carvey said. "He seems like the type of dog that would love to be spoiled and pampered. He would also love a doggy playmate, and lots of exposure to new and exciting things."
