Why is my puppy aggressive towards dogs and people on walks?

Updated On September 23rd, 2025

Pet's info: Dog | American Pit Bull Terrier | Male | unneutered | 3 months and 7 days old | 50 lbs

He growls and has a strong position when it comes to older dogs and he does the same thing with people but he doesn't do that at home just when I take for a Walk

As a puppy, Zeus does not know what is appropriate behavior towards strangers and other dogs, and he is reacting with aggression when his personal space is invaded. This is a very important time in Zeus's life where he needs to learn how to socialize with other people and dogs. He has to be taught how to interact correctly so that he doesn't display aggressive behaviors as he grows up. One of the best ways to do this is to enroll him in puppy preschool or training groups. I would speak to your vet for a recommendation to one of these, where he will learn how to react appropriately when approached by strangers or other dogs, and can also learn basis commands such as sit, stay, and lay down.
