This is a Real Sign

It says dog, it's just that part of the paint came off, you can tell by the curve of the letter.

Observe the slightly darker color where a head would be if this log was a dog. Paint was scratched off or something to change the D to an L and to make the dog look like a log. Great meme though. Upvoted despite this.

I never met a dog that looks so much like a rectangle
