I think you just wrap it and wait for it to grow back.
By picking or peeling the toenail off.
If a toenail gets damaged, by a shock, or too short a shoe, it can "die" and a new one starts to grow underneath. Eventually the damaged one falls off. That may or may not be your problem. Check with a doctor.
If you drop something heavy on your toenail, it will kill the nailbed and it will fall off. Usually will grow back eventually.
Yes.
No! Let the new toenail grow to replace it.
The dead nail will begin to detach (and eventually fall off) while a new toenail grows in.
well you don't really want to get your toenail taken off because it really hurts but it can fall off if you stub it very hard or if you get it stuck under something like a door
It should do...unless you're a zombie.
Seek medical attention as soon as possible.
Foot fungus.
You should not put artificial nails on an exposed toe. If the nail fell off, it should be protected until the nail grows back in.
Take it to the vet. They will have to cut the nail off to appropriate size which might make your pig bleed. Do NOT do this yourself. You should trim your pigs nails weekly.
