Hello, my name is***** and I have over 20 years of experience as a veterinarian.
I understand that you preferred Poppy's ears in a folded over position.
Many dogs in breeds that eventually have erect ears start with ears that flop over at the tips. That's because ear cartilage strength is usually not at adult strength until 14 to 16 weeks of age. Although this seemed to come about with a frightening episode it is entirely possible that one or both of her ears were going to be erect eventually anyway.
Dogs that have weaker cartilage won't have ears that fully stand, so if her ears weren't standing at 8 months of age they probably would remain floppy for life.
If you really want her ears folded over you can try to "train" the ear into a folded over position, but it may not work. I have had some owners use weights glued to their pup's ear tips to get them to stay folded. This works best when they are younger, so if you'd like that it is worth trying now as it won't hurt her. Here is a link to an example: http://www.showdogstore.com/cherryknoll-earweight.aspx
Best of luck with Poppy, please let me know if you have any further questions.
