UK - Many dog owners wonder what their pets are up to when they have the house to themselves. One TikToker found out and caught the hysterical moment on camera for all to see.

The viral clip of the cocker spaniel named Teddy Boy kicks off showing a clean and dog-free living room. The caption says, "Up to no good as usual."

Suddenly, Teddy Boy bounds into the room with a sandal between his teeth.

The furry thief must have decided being home alone gave him license to chew something off limits. "When you didn't realize Mum was in the room and would catch you red handed," Teddy Boy's owner wrote along with the video.

Cats Cat owner is shocked to see his pet on a cliff!

The dog runs around the living room with his prize, chewing happily until he comes near the couch and realizes his mistake.

As soon as he realizes he's not alone, the dog stops in his tracks. He holds the sandal in his mouth and gives his owner a sheepish side eye.

The hilarious clip has been viewed 26 million times.

Teddy Boy's reaction to being caught with his owner's footwear in his mouth thrilled millions. The clip has garnered almost 5 million likes.

Thousands filled the comments with laughing crying emojis and wrote things like "Omg I love this so much!!"

TikTok users couldn't help but giggle over the dog's reaction. "Lol the way he froze then gave the side eye," one wrote, while another said, "The side eye realisation. if I stand as still as a statue she won’t see me."

Cats Cat has hilarious reaction to his own reflection!

"The way his little eyes just slowly look from the shoe to mom," a third user gushed.

The only question is: did Teddy Boy learn his lesson after being caught, or will he go for his mom's shoes as soon as he's on his own again?
