Neutering is always helpful with this type of issue but it may take a while to see a change as it takes some time for the hormones to get out of his system. But it will help him with aggressive and territorial issues.
An obedience class might be helpful. A place where he can take a class with 1 or 2 other dogs and learn how to behave with other dogs and how to walk properly on a leash. It should be a good experience for everyone.
Try keeping him on a very short leash so he is right at your side all the time and you can make a correction easily even before he actually lunges at someone or barks. |
