TikTok user 'xcoraaa' has captivated the internet with over 4 million views in just three days, thanks to a hilarious and slightly spooky clip of her black Labrador, Luna.

Cora bought a pink LED neon collar to keep track of Luna at night. But the result was more eerie than expected when she filmed Luna bouncing around the backyard.

The collar appeared as a glowing smile, Luna’s eyes reflected yellow from the flash, and her dark body was invisible until she got close.

I can’t see my all black dog at night so instead of trying to guess where she is I bought her a LED neon collar to spot her in the dark. I went to go take a cute video of her bopping around the backyard in the dark with this pink collar floating and instead of it being just cute it also is a little scary. The LED collar turned into a smile and her eyes are glowing yellow from the flash on my phone, however you can’t see the rest of her until she is closer so she just looks like the void but a glowing smiley face version. Once she realizes I can finally see her she got super excited. My puppies name is Luna.
