Are Border Collies aggressive?

No, Border Collies are not aggressive dogs. These friendly pups do have plenty of energy to burn, though, and without proper exercise, they may exhibit behavioral issues. While any dog breed can potentially exhibit aggression, Border Collies are generally known for their gentle and friendly nature.

If you are concerned by any signs of aggression or reactivity in your dog, be sure to address it promptly with the help of a professional trainer or behaviorist. Pain, discomfort, or underlying medical conditions can sometimes contribute to changes in a dog’s behavior, so it may also be worth visiting a vet to rule out their health as a cause for signs of aggressive behavior.
