First off, go to any pharmacy and pick up wound wash saline, antibiotic spray or ointment, cotton gauze, and self-adhesive flexible bandaging (this is the same as vet-wrap, but available for people in pharmacies). All this stuff is in the first-aid section of any pharmacy. Wash the wound well with the spray saline, then pat dry with gauze, then apply antibiotic spray or ointment, then gently lay fresh cotton gauze over the wound and carefully wrap it up with the self-adhesive bandage. Use more than you think you'll need. Don't make it too tight as you don't want to cut off circulation, but tight enough to stay on. This will buy you time to get to a vet who can do stitches.
I would not use superglue on a skin tear wound.
