A video demonstrating exactly why they call it "puppy love" has gone viral on TikTok racking up a whopping 1.5 million views.

Newsweek spoke to the Pomeranian's owner, Kayla, about the comical clip that shows 8-year-old Hadia lying on her bed. Speaking to the camera, Kayla (@klacupcake) explains that "one of the funniest things" she did as a dog owner was teach her pet her boyfriend's name.

At first, the American photographer based in Cologne, Germany, doesn't say his name, while she explains: "She is madly in love with him. She thinks that my boyfriend is her boyfriend." Then Hadia jumps up and barks every time Kayla mentions Felix.

She shared with Newsweek the story of her and Felix's journey that began back in 2018, and it might not surprise some women to learn that Felix was initially opposed to the idea of getting a pet.

"My boyfriend had never had a dog before and he didn't want one," she told Newsweek, adding that it took months to find an ethical breeder in 2018, then they came across Hadia, then 2, and decided to take her home for a trial period.

"Pom's are notoriously clingy and they can be skeptical of new people and slightly closed off. Hadia was no exception," she said. "She stayed under the couch quivering for the first three days she was with us. On the third day, we watched a documentary on the couch, and my boyfriend gently stroked her fur the whole time. She fell in love and hasn't looked back since.

"She has stayed this in love with him the entire time. He can do no wrong in her eyes. She loves him and follows him everywhere he goes. He is the absolute center of her universe. She protects him from dangers like the doorbell, birds, and other dogs. She would never let him go to the toilet alone."

Kayla refers to Felix as a "green flag" in the comments, highlighting his positive traits and the fact that he has passed the "vibe check" with Hadia. This is significant because, according to a survey of 1,000 U.S. adults conducted by Talker Research for Newsweek, a pet's opinion can greatly influence a relationship.

The survey found that 61 percent of millennial respondents (born between 1981 and 1996) said they would consider ending a relationship if their partner didn't get along with their pet.

By comparison, just 39 percent of Generation Z respondents said they would take these measures against a partner who clashed with their pet.

Kayla told Newsweek: "If your boyfriend doesn't like your tiny dog it's a big red flag."

In this case, Kayla doesn't have to make any harsh decisions as it's clear Hadia has a soft spot for Felix.

Newsweek previously spoke to veterinarians to find out other ways that a canine shows their love.

Dr. Sam Meister, CEO, and founder of PetWellClinic said: "If your dog is excited to see you, sticks by your side when at home, and displays affectionate behavior toward you, such as leaning against you, and seeking your attention, you have a special place in your dog's heart!"

During the video, Hadia expresses her love vocally, though we don't see the pair reunite. However, there's no doubt she would show her affection through one of the signs experts mention, such as wagging her tail, following her favorite friend, or getting up close by rubbing her face against him.

Dogs have scent glands in their heads, so when they rub their face or head against you, they're marking you with their scent. This action signals to other dogs that you belong to them, letting other suitors know to back off!

TikTok Reacts

So far, the August 20 video has over 317,000 likes and almost 940 comments.

Kayla notified users: "The howl is actually super rare, she only does it like once a year. She blessed us with one today."

"I think she's a fangirl," said one user, and another wrote: "That is such a positive sign when your dog likes someone."
