I'm trying to remember what this horror movie is, althoguh I dont have a lot to go on but a few iamges in my head from when I was younger. All I remeber for certain is that there was a blind guy with a dog in it...not like an extra but one of the group of kids who gets slashed.

It was your typical late 70's/early 80's slasher flick. I know thats vague, but anyone have any idears at all?
