Today, I picked up a dog, whose front right limb was broken. The X-ray showed that there was a missing bone in it, and the doctor amputated it.

If the dog is injured, it will sleep. My dog was not injured when it was hit by a car, and it stayed asleep for a few days before coming out. And dogs themselves love to sleep. My dog is sleeping except when he goes out to eat and play.

the wound will hurt, and it will take a few days. But if it doesn't hurt, it will hide if you apply medicine to it. My dog lost hair on his feet when he was a child, and it didn't hurt or itch, and it kept shrinking when I applied medicine to it.

If you touch your back, it's okay if it feels comfortable when you touch it. If you poke it, it's possible to touch it without touching it. Because when I comb my dog's hair, every time I comb it to the back near the bottom, it shrinks like an itch.

the above is my experience in raising dogs, which may not be accurate. You should mainly ask the doctor.
