I've raised pigs and seen wild boars do the exact same thing in order to "look up": they sit, in order to elevate their angle of vision.

Humans can't look behind themselves. The neck does not rotate that far. The solution: the entire body rotates.

Even if you are looking straight ahead at the horizon you will see stars just due to your cone of vision.

For those wondering if it’s true that pigs can’t see the sky:

There's a fair bit of debate on the subject of a pigs ability to look upwards, but here's the gist!

Pigs are able to look up a bit and therefore can see portions of the sky, but as a result of their neck's anatomy they aren't able to look directly above them.

Pigs have short, muscular necks with limited mobility that prevents them from tilting all the way up. There are plenty of other ways for pigs to see the stars, such as rolling over on their backs, taking a few steps back from what they want to see and tilting the rest of their body in line with what they're looking at.

I still thought the sentiment in the post was nice and sweet though.

Yeah but like. Pigs roll in mud. They literally look at the sky when they roll in mud. The one thing theyre known to do, roll in mud. When you think of a pig, and theyre rolling in mud, they look all around including into the starts. While rolling in mud. The one things everyone thinks of when they think of pigs.

They can still look up. They can lay on their back which they do.

Assuming that the poster is making this post on mobile, "4the" saved them one keyboard press, and "2b" saved them two keyboard presses, all at the expense of readability.

Where pigs live, they can see stars without looking upwards. Some people in here don't get outside towns a lot I think!

It's going to sqeal like a maniac and maybe bite you while you ever so gently do this oddly sexual act to it

I thought it was dogs that couldn't look up

I thought only dogs couldn’t look up
