Pets are the most wonderful thing...

But in many instances, they most certainly aren't the most photogenic.

Us pet owners love nothing more than taking endless pictures of our furry friends...

And sometimes, things don't exactly go to plan behind the camera lens.

Thanks to optical illusions...

Our pets sometimes are left looking completely unrecognizable. Keep scrolling to see a few bizarre examples...

Take this dog, for example...

Or these 2 dogs...?

Here's a couple of very cute dogs...

Even though we aren't entirely sure exactly where their heads start!

Now, just look at the perfect timing of this one!

A light afternoon snack?

A young boy with a dog's head?

Or just a young boy taking a nap with his best friend?

This is something you won't be unseeing for a while...

This would be a great idea for some doggy fancy-dress!

These golden retrievers appear to have merged into one...

Best friends forever?

Now, this is just way too adorable...

Nothing like giving a giant dog a big cuddle, right?

Here's a dog casually fishing...

Now, that's something you don't see every day!

Now this one really puzzled us...

Can you see it yet?

Here's a dog running into the ocean...

About to take flight...?

This is one of our personal favorites...

Looks like this little pupper got himself stuck in a bubble!

But there is one optical illusion that has really been confusing the hell out of the internet recently...

And it is this bizarre little thing. People were leaving comments of horror, such as, "My first thought was, 'why is there a meat sack with legs and how is it alive'," and, "I didn’t even understand what’s going on with the dog."

It turns out that it is simply just a 3-legged dog cleaning itself.

Simple! Make sure to keep scrolling to check out the optical illusion on Twitter that has people mistaking a car door for a beach...
