Imagine his surprise when it became apparent that the creature had nothing in common with a dog.

The guy posted a video on the internet, showing the stray he brought home to his house at night.

As reported: Fakta.today

The man recorded the video in the morning. At the beginning of the video is his own dog.

Then the owner turns towards the new "dog."

At first, the animal is hard to spot as it tries to hide behind a trash can.

But then it becomes clear that it definitely wasn't a dog.

It was only in the morning that the owner realized he had actually taken in a calf instead of a dog.

And the animal confirmed this fact with its characteristic "moo."

Despite the fact that the domestic companion wasn't a dog, the man didn't get rid of it.

He even created a separate Instagram profile for the calf, where he shares its photos.
