lol go easy on you!
Ok well some yorkies have floppy ears until they are around 4 months or so. Pixie's ears did not stand up fully until about 5 months. She had one up at 4 months and then another at 5. sometimes they tell you to tape them and there is a special way to do it. I am not familiar with it. Also they tell you to keep their ears trimmed bc the cartilage is forming up until 6 months and it will help the ears stand up.
I hope this helped
