Wow they look awesome! Great job on those ears! It's so nice to see some danes with their ears done! I had to post my dobie for six months since she was show cropped and her ears stayed soft for so long. I'm guessing it will take some time with those boys. If Athena's ears were at all floppy after a few days to a week, they went right back up for a week.
I also have to add that the vet that cropped their ears did a fantastic job. I can see a nice devil's tip on the fawn, and I think I can see a decent one on the brindle, but the angle of the picture is hard to tell. That's not an easy feat!
Have you posted ears before?
