Is the cut clean or jagged? From what i've heard, the pads heal kind of like the mouth - from the inside out.
I don't know that it would harm anything at all to put a thin layer of glue over the torn skin, I seriously did it for a few weeks on his pad because nothing else held and it kept it protected. I do remember that Bandaid makes something called liquid bandaid/second skin - so you might want to ask your vet about using that. It might be more flexible than super glue.
Depending on where it is, you may even be able to put a bandaid on it, like the ones they use for blisters. The entire thing is cushiony, so I've found they hold up better than regular ones.
Here's hoping it's healed a lot by then, though! I bet it will be. We went to the country not 2 weeks after Luka's paw and despite me holding him to carry him out of the car...
He definitely jumped right onto the gravel road. It didn't bleed or anything. So, don't be too afraid. <3 They're hardy dogs.
