A couple who recently welcomed their first child are certain he will become "the best of buddies" with their dog, even if the dachshund is currently in "denial."

Chey and Jeremy live in Melbourne, Australia, with their baby son, Louis, and dog Cooper, who was an "only child" until Louis arrived earlier this year. It's clear Cooper sometimes misses being the center of attention, as a clip shared to Chey's TikTok account @life.with.chey in June proves beyond a doubt.

In the video, which has been viewed more than 2.5 million times, architect Jeremy lies on the ground, cooing and smiling at his son. But Cooper immediately walks up and takes the spotlight, putting his head right up against Jeremy's face, almost blocking his view of the baby. And as Jeremy laughs, he cuddles the dog into him.

"I think they call this stage denial," Chey wrote on the video, adding in the caption: "I don't think Cooper's too stoked to give up his only child status."

Chey told Newsweek that Cooper is "the most gentle, loving little boy ever," and is "really great" with Louis, despite initially being cautiously curious.

Expectant parents are advised to make the introduction between dog and newborn slowly, and to begin preparing the pup before the baby is even born, by getting them used to the scents, sounds and change in routine a newborn brings to the house.

The American Society for the Prevention of Cruelty to Animals (ASPCA) suggests introducing items like strollers and high-seats to the dog, and expectant parents wearing baby shampoo and powder to get the animal used to the new scents. Playing audio of baby sounds, including crying, before the newborn is brought home, is also advised.

"I absolutely see them being the best of buddies when Louis begins to crawl," social media worker Chey said. "We have a very long corridor in our house, and usually Cooper loves his ball being thrown down it so he can bring it back, to be thrown all over again. We imagine Lou will love throwing the ball for Coop, and eventually the two of them will be chasing each other up and down the hallway."

TikTok users fell head-over-heels for Cooper, with hundreds commenting on the video, laughing at the "needy" dachshund.

"Coop said nah you barely know that kid," one wrote, another agreeing: "He's like but I'M the baby."

"I'm dying," another wrote. "He's like um dad have you forgotten about me?"

Some were heartbroken over the dog begging for attention, with one writing it "makes me sad knowing he's sad".

But Chey assured Newsweek: "I just want to reiterate that he is a VERY loved dog and has a special place in our family."

They brought Cooper into their home three years ago at the height of the pandemic, and the little dog has repeatedly proved popular on social media.

He previously went viral for refusing to take another step on a walk as it was "chilly outside," even though he was wrapped up in a coat.

At the time, Chey told Newsweek the pup "doesn't enjoy going out in the cold. He kicks up a stink if he has to."
