I've seen a dog that ugly in person. It was in Paran?, Entre Rios, Argentina. There are tons of stray dogs and it s common for them to have "sarna" which I think is some kind of blood disease that they pick up in the waste water. I will tell you that I never did get very close to that dog and it certainly wasn't anybody's pet. Unfortunately I never got a picture of it, but I tell you what, that when you looked at it closely it was like you were lookin the devil straight in the eye, it was spooky.
