Let’s take this Pitbull avengers shirt. It’s a fact that puppies are adorable! But the thing about puppies is, well, they grow up. And as they mature, their personality develops and that’s when you really find out whether your Pit Bull is dominant or submissive with people, or whether she is aggressive toward some, none or all dogs.
Dog-intolerance and dog-aggression are traits that do not develop in some dogs until they are fully mature. It is possible that the cute little puppy you adopt who is friendly with all other dogs may not like other dogs at all later in life, even dogs she has grown up with and lived with for her entire life. Both nurture (environment) and nature (genetics) play a role in determining a dog’s mature personality. This doesn’t mean that Pit Bull puppies should not be adopted, but if you want to know how big your dog will ultimately be and how she will act around humans and other animals, you may want to consider adopting an adult.
