Just be careful not to expect them to stand too quickly. She's pretty old to be having them cropped. They can appear to be standing inbetween postings and then they wilt. If you let them stay in that wilted position, at all fopping for ANY amount of time, you are going to have real problems getting them to stand. They must never flop at all.
She also may have more pain than a very young pup and also has been without them all this time so it's really going to be foreign to her. Where as a 7 week old pup hardly has had time to notice any different. So, be careful she doesn't mess with them. My pup never did. He was just so accustomed to the posts. Your pup may not be.
You need to clean them, air them out (about every 4 days) just while you prepare your clean posts and then post them right back up again. When you get to the point where they'll stand for a day, but then start to wilt, get them re-posted. When they stand for a week and then start to flop, they're not finished yet. You need to post longer than you think usually.
Lyric was a year old before his were solid. But he was a little bit of a late bloomer. But not that unusual. Some take nearly that long. At 4 months, they would stand for a day, if I remember correctly and by the end......wilting. His were done at 7 weeks by the breeder's cropping vet.
I had a wonderful site for instructions and pictures and now it doesn't link up for some reason. It's gone. But if you're getting help from this gal, hopefully all will be well. Good luck.
She is adorable!
