Hello, I think that is how Harley is going to have his ears. Its unlikely he has had an ear infection for that long if he has not been shaking his head, scratching at his ears non-stop, or developing a head tilt, crying or whining in pain, or if he doesn't have discharge with a foul smell. All of these are signs of an ear infection.
Harley may continue to have that bend in his hears as his normal self. As the cartilages develop fully, he may change the appearance of his ears, but at 9 months, he may not change them.
If you note any of the above signs, then Harley should be seen by a veterinarian to have his hears checked. Hope this helps and best of luck.
