Do all border collies raise their ears?

Not all Border Collies raise their ears, as ear positioning can vary based on individual genetics, mood, and the dog's environment. Some may have upright ears, while others may have semi-erect or floppy ears. Additionally, a dog's emotional state can influence ear posture; for instance, they may raise their ears when alert or excited. Overall, ear position is not a definitive trait across all Border Collies.
