Tennessee - A dog owner had the scare of their life when they thought "something horrible" had happened to her pup. After making a funny revelation, she's still laughing along with millions of TikTok users.

This black and white pupper had a spot of a different color!

Everybody knows that ketchup can look like blood, but did you know that a squished tomato can look like a real open wound?

A viral video proves it can. The crushed red fruit became a very convincing fake wound when stuck to the behind of a doggo with white and black fur.

Dogs Dog can't understand why Santa Claus decoration won't pet him in adorable video!

The star of the clip is a rescue dog named Jack. For a few scary seconds, his owner was seriously worried about their four-legged friend.

"I thought something horrible happened to my dog," Jack's owner captioned the clip.

The camera then zooms in on the red spot on Jack's hip that looks like a gaping wound – until you see the squished tomato skin.

"I thought it was a giant sore, or burn at first," Jack's owner wrote. "I’m so happy the goofball just sat on a tomato!"

"This dog cracks me up every single day," they added.

The funny false alarm has since become wildly popular on TikTok and the clip has 8.9 million views and counting. Users can't stop giggling and commenting with crying-laughing emojis.

But that's not all.

Other dog owners wrote in to say that they, too, have made similar mistakes when their dogs got food or something unusual stuck in their fur.

Cats Cat's tragic secret uncovered by X-ray – how could he live like that?

One wrote, "I thought my dog had a lump that might be cancer, turned out she'd sat on a Werther's original [candy] and it was stuck under her fur."

Another shared that their dog's encounter with a different fruit freaked them out: "Thought my dog had hurt herself the other day. Turns out she’d just managed to smoosh a raspberry on herself."

Adding to the fray, another pet owner said a makeup mishap almost sent them running to the vet: "My dog stepped on red lipstick on a sidewalk and tracked it inside and we thought he was bleeding from the foot"

If the stories prove anything, it's that dog owners should apparently make sure some "blood" isn't just something squished – as pups can easily step into some mischief.
