I seriously feel that he would be fine without the tape until he's totally healed, and I don't like that the vet put tape back over the raw incision site. Please realize that by doing this, the healing process may be hindered, or worse, the ear can become infected, which is really what is biggest concern at this point.
Apply the triple antibiotic each time you clean the incision with peroxide. I prefer to do this twice daily. My vet tells us to remove the scabs on the incision line to create a smoother scar, however, I have spoken with others who's vets have not told them to do this, so it seems to be the personal preference of the individual vet.
One thing that I have found with ears is that the more you fuss, the harder it will be to get them to turn out well. If it were me, I'd leave them flop until the edges are fully healed, but that's just me.
With posting, what I do is to take the foam backer rod and turn it so that the rod naturally curves out and away from the head. I then cut the part that will be inserted into the ear at an angle. Then I back tape (meaning winding the tape around the rod backwards so that the sticky side is facing out) each rod with Johnson's and Johnson's waterproof tape (because it's stickier than other tapes). Make sure the insides of the ears are shaved free of hair and have been thoroughly cleaned (I prefer to use noxema pads or witch hazel.) so as to remove excess oils from the ear. Insert the rod into the ear canal and then stretch the ear up and out over the rods, going in the same direction as the rod. Press the ear firmly to the rod and secure in place with two more strips of J&J waterproof tape, one up toward the tip and another down closer to the base. Then use a breathable athletic tape or Vetrap (I prefer Vetrap because it's reusable and comes in cute colors) to cover over the rest.
IMPORTANT: DO NOT tape too tightly. To do so will cause a loss of circulation in the ear and can cause the tips to die off and fall off. My gauge on whether or not the tape is too tight is to leave the tips of the ears uncovered (don't tape over the tip) and watch them for 15-20 minutes after taping. If the tips start to swell or turn hot and red or purple, remove the tape immediately and start over making sure to go looser with the tape the second time.
I can't stress how important this is. I have a friend personally who's show prospect bitch lost an entire ear because the tape was too tight, and it cut off the circulation to her ear. It does happen.
It is also very important not to tape until the ears are totally healed. To do so can cause infection from bacteria getting trapped on the incision site underneath the tape.
Good luck, other than that, I have no other advice to give.
