I have an 11 weeks old husky pup. I got her at 5 weeks (we didn’t know she was so young until we took her to the vet the night we got her). Both ears were floppy at 5 weeks and then by 7 weeks they were both standing up, but shortly after that one ear went down again and hasn’t come up since. I’m not sure if something happened, but I’m starting to get nervous it won’t stand back up. Should I do anything to help it stand?
