It is the kind of invasion dog lovers would be happy to have.

This is the moment eight husky puppies break through the slats of a vent in a door and run free.

In a viral video posted on Aww Station from Xingua92, it is not entirely clear where the puppies are trying to get out of or where they are going.

I want to break free: the adorable puppies try to bite their way through the vent's slats to get out

The video shows the puppies pawing at the slats in the door vent, before three of them manage to stick their heads out or chew the slats.

As the first puppy, a black and white husky, pushes his way out successfully from the rabble, it starts an avalanche of fluffy dogs behind him.

Wait for me! The puppies push their way through to freedom, though from what and to what is not clear

Users were quick to make a comparison between the puppies breaking out and the Walking Dead, pictured above, a horror series where Rick Grimes fights zombies

No sooner has the second one broken free than the third, fourth and fifth follow.

One puppy soon realises that he will have more success if he doesn't chew on the slat, and also jumps free.

The last puppy is somewhat delayed as he follows his brothers and sisters out of the room, but the black furball eventually makes it through.

In total, eight puppies make their way out of the room through the door's now very broken gap, leaving one bigger husky behind.
