Canada - Robin Smith is used to her two pups cuddling in bed with her every morning. But on Saturday, she got a shock when she opened her eyes, and a third dog had joined!

The dog owner was stunned to discover that her own four-legged friends, Yogi and Dogi, had been joined by a third pup.

Smith pulled out her camera to capture the curious moment, which she shared on TikTok.

In the video, she pans the camera to the left and tells viewers: "This is not my dog!"

Cats Shelter cat's mysterious ear tattoo sparks a heated online debate!

The uninvited guest is the neighbor's dog, named Marbles.

"We have a dog door," the pet owner explained. "At some point in time, she came in the dog door and climbed in bed with us."

When Smith tries to pet the animal, it takes off running.

"Marbles, Marbles!" Smith shouts in the video.

But Marbles was already gone.

Smith explained to inquiring TikTok users that her neighbors have a ten-month-old baby, and since Marbles is now 14-years-old, she probably needed a little "peace and quiet."

The clip now has over 700,000 views, and thousands of comments.

Some funny reactions included:

Cats Cat has hilarious reaction to his own reflection!

• "Pleeeease tell me you asked your neighbors if they 'lost their marbles?'"
  
• "I want to wake up with extra doggies."
• "Your dogs looked at them like, 'Aren't you staying for breakfast?"
• "Why does this never happen to me?"
• "Yogi and Dogi invited Marbles over for a cuddle."

Since the first video, Smith has posted at least two more morning visits from Marbles.

"Marbles is my alarm clock," she wrote. "This is definitely a regular thing."

Perhaps the third time is the charm, and Marbles may have found her furr-ever fallback home.
