Same friend I just mentioned sent me the pics that can be found in this link -http://www.snopes.com/photos/animals/porcupinedog.asp
This one is true. I can't imagine how much pain this dog must have been in! Or how much the vet bills were. Would you want to be the vet that had to work on her?
That's and English Bull Terrier, though. Don't know why they are calling it a pit bull.
I had an English Bull Terrier growing up. He died the week after I got married and moved out. :\ He was a WONDERFUL dog. They are the Spuds MacKenzie dogs, by the way.
