I was told 12-14 weeks is the optimal time for ear crops. After that some vets won't do it, other vets will do it but it is kinda late. I got Brandy when she was 4 months old & looked into getting it done on her too. Well, they said they would do it but wouldn't be able to guarantee her ears would stand. I thought it wasn't worth it, I would end up spending all that money $200 or so and putting her through all the pain & then they wouldn't stand I couldn't take the chance. Then when I look at her I think she is beautiful the way she is without the crop.
I had Britnee's ears cropped when she was 12 weeks old and they stood up from day one. It was only $100-150 for her spay and her crop. But that was also 9 years ago.
