The pup is frozen and unmoving, even when the tiny cat looks up at him and then over to their owner in confusion.

"His face," reads the post's caption.

On-screen video text reads, "the cat laid on him for the first time and he's horrified," but commenters jumped in below the clip to say that the dog doesn't necessarily look horrified – although he's definitely freaking out.

"'Don't move, don't move. Stay calm. they love me. omg.' the dog probably because that would be me," wrote one user in the comments section.

"His like 'no sudden movements, this is a once in a lifetime thing,'" added another.

According to other videos from the account, the pair are now good friends and seem to cuddle often!
