4. Lack of Training: Dogs that haven’t received proper training may not know how to behave appropriately, leading to hyperactivity or craziness.

5. Medical Issues: Some medical conditions or pain can cause sudden changes in behavior. It’s important to rule out any underlying health issues by consulting with a veterinarian.
