No, Greyhound dogs are not aggressive. They tend to be friendly and sociable with both people and other animals. However, like any breed, individual temperament can vary, so proper socialization and training are important to ensure they are 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.
