This is probably the worst thing you will watch online today. Don’t say we didn’t warn you! Here is what the video uploader had to say about the situatioun:

We bought a puppy off craiglist and they told us he had worms but he was dewormed. Well this is what I found 2 days after we go him. I taped it because I figured no one would believe me.

Proceed with caution.

Luckily the pup’s owner assured us she “took him straight to the vet” and he is “all better and happy”.
