I just wanted to share a success story for those of you worried about your pups ears. My boy Rainer still had floppy ears at 7.5 months, even after me trying to tape and glue them myself. I finally relented and talked with my breeder, who gave me very specific glueing instructions, and they have been up since.
When I came to my breeder she said I had about 20-30% chance they would go up and stay up, and said I should have come to her much much sooner (like at 4-5 months)
Moral of the story, talk to your breeder folks.. even at 7.5 months, it's still possible those ears can come up.
