This is a perfect reason why some vets have no business cropping ears. Some just don't know what they are doing.
I would let little Chevy's ears heal. Don't worry about any taping until they are all healed. You can use some antibiotic ointment on the edges to keep scabs from forming and help them heal faster. He will enjoy the gentle rubbing. And it will be good for him to have some positive touches after two painful tapings.
Can you ask around and try to find a breeder to help you tape them later? Do expect to pay them for their supplies and time, although I am sure it won't be much. It doesn't have to be a boxer breeder. Dobes & Danes all tape the same way. Just tell whoever is helping that he won't tolerate posts in the ears. Some pups just will not tolerate having the ears posted. I have two older pups whose ears are pretty well up. One would not tolerate anything down her ears and the other didn't care at all. They are all different and there are many, many different methods of taping.
To be honest I can't imagine a Dane's ears standing "all by themselves" without taping.
One other note. Please don't try to tape them yourselves. You really can do some damage, if the tape is on wrong or too tight.
Hang in there, it will get better. Give Chevy a big hug and some special treats. He will forget this experience.
