Initially, some Pitbulls were bred to be aggressive and enhance their fighting abilities. This makes them prone to aggression and more likely to get into a fight with other dogs. However, it is important to note that the aggression towards other dogs does not translate to aggression towards humans. Once they get along with you, Pitbulls can be extremely affectionate, loyal, and friendly dogs. If you want to your Pitbull puppy to be friendly with other dogs as well, it is advisable to provide them with adequate obedience and social training from a young age.
