Are Cocker Spaniels aggressive?

No, Cocker Spaniels do not tend to be aggressive. Like any breed, individual temperaments vary among these generally friendly and affectionate dogs. However, like any breed, individual temperament can vary, so proper socialization and training are important to ensure they grow up to be well-behaved.

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 their behavior.
