Every pet owner knows the guilt that comes with leaving your pet at home. But at least most people only have to say goodbye once, unlike one woman who faces that guilt until she gets on her bus.

Lowri, 34, lives in Wales, U.K., with her 2-year-old Staffordshire terrier-pointer cross, Elmo. She credits the dog with saving her life; she told Newsweek that Elmo has "helped my mental health massively" and "gives me a reason to leave the house which I usually struggle with due to social anxiety."

However, while Elmo has helped Lowri get the confidence to go out, she still feels guilty leaving him behind; and in her case, she has to face his sad face twice, as he watches her wait for her bus from the window.

In a TikTok shared to her account @theelmoshow on June 18 which has racked up over 23,000 likes and more than 134,000 views, she films herself standing at the bus stop. The camera then zooms into apartments across the road where Elmo is staring out at her between the curtains.

Lowri wrote: "POV [Point of view]: You have to deal with the guilt twice because the bus stop is directly opposite. His little face."

Lowri added in a caption: "If you have a staffy then you know. Where's my human going?"

And TikTok users did, indeed, know, and they flocked to the comment section to share how they related to the clip. One wrote: "I'd genuinely walk to a further bus stop. Couldn't cope with them watching me leave ha-ha."

Another commented, "I'd literally have to walk to the next bus stop," and one posted: "The way I'd be sobbing at the bus stop on the daily," to which Lowri replied: "I was close."

One heartbreaking comment read, "once you've left he probably looks at every single bus thinking it's you coming back just to be disappointed all over again," with Lowri replying: "Nah why did you have to put that thought into my head?"

Lowri said she was "sure Elmo would be loving the attention if he knew the reaction it's had."

The staffy mix, who turns 3 in August, "always wants to be at the center of attention and entertainment," Lowri added.

Elmo is "dog reactive" due to being attacked previously, but is "the softest, most loving boy, and helping him with his reactivity has given me a different purpose in life," Lowri said.

"I have experienced trauma and so I feel like I understand what he needs from me; safety, stability and compassion." She added: "He's saved my life."

Owning a pet has many mental-health benefits, according to the Mental Health Foundation.

It provides structure, increases physical activity, provides companionship and reduces anxiety, thanks to the unconditional love offered by the pet. Feeding and caring for an animal can also give an individual an elevated sense of purpose and responsibility, boosting self-esteem.
