Serena Williams' grand adventure of eating dog food and shitting her brains out started with her Snapchatting a picture of a hotel that had its own dog food menu.

And she was like...

...seems legit. I would try.
Then she ordered the salmon and rice, and it looked like this. Notice the fancy spoon...

...again, seems legit. I would try.
And so she tried it...

...and...

...poop attack.
It wasn't pretty.
In the end, Serena wrote a little warning on the dog food menu.

Lesson learned: If you are a human — DO NOT EAT. IT MAKES YOU SHIT!!
