I have a girl with one floppy ear that I posted til she was 9 months. I stopped posting because she kept having reactions to everything we used to post her with. She got an infection during posting, and had to have it down for 10 days, we started posting again and it was standing at 7 months, then we had her spayed and after that it flopped. I started posting again until 9 months and it just wouldnt stand. with all the small sores inside and out of her ear I stopped posting, she had gone through enough and she isnt being shown so I left it.
