My vet used that really thick white tape, not vet wrap, but another. She wrapped it up so well. PLUS she put that Avi-soother cream by Harrisons on the wound AND I put it on the tape. I put that cream on the tape 6-8 times a day. It tastes bad so he didn't touch it when the cream was on it.
The hospital cage was a soft bottom, towels and covered in newspaper. Newman was on the med so he was really tired. He just sat with his foot up the whole time.
MY mistake was putting that syptic pencil on the open wound which irritated it to no end. He picked and picked. Then it needed stitches.
Hopefully your vet will wrap it, give him a little sedative, and something for the pain.
Don't worry, once it is wrapped really well the toe will start to heal.
