This actually was big a while back. I don't know who made it though.

I saw something similar to this back in Iceland. It was a picture of a cat that said (translated) "Found dog. Looks like a cat. He's pretty cool. I'm keeping him. Don't look for him anymore" and then they drew the Van Halen logo in a few places on it.

There's another dog somewhere that apparently tastes like chicken. :|

I think you're thinking of the one desolatefix made:

With some templates, you can see previous memes that have been made with it at the bottom of the screen, when you're captioning it.
