French bulldog why do French bulldogs ears fold backwards?

French Bulldogs have distinctive bat-like ears that can sometimes appear to fold backward due to their unique anatomy and the way their cartilage develops. In some cases, their ears may not fully stand upright due to factors like genetics or the age of the dog. Additionally, the position of the ears can be influenced by the dog's mood or environment, making them appear more relaxed or folded back. Overall, this characteristic is part of their charming and playful appearance.
