Here's why you shouldn't try to fix this on your own:
* Safety: Your brother's safety is paramount. Trying to address this alone could escalate the situation.
* Underlying Issues: Growling, attacking, and biting are signs of underlying issues. These could be fear, anxiety, resource guarding, territoriality, or even pain. Without professional help, you might not be able to identify the root cause.
* Professional Expertise: A qualified dog trainer or behaviorist can assess the situation, understand the dog's motivation, and provide tailored solutions. They can help you create a safe environment for everyone.
What You Should Do:
1. Seek Professional Help: Contact a certified dog trainer or animal behaviorist immediately. They can provide a personalized plan.
2. Ensure Safety: Keep your brother and your dog separated until you have professional guidance.
3. Supervise Interactions: When under supervision, maintain a safe distance between them.
4. Avoid Punishment: Punishing your dog for aggression can worsen the problem.
5. Consult a Veterinarian: Rule out any medical issues that might be causing the behavior.
Remember: Your dog's behavior is a form of communication. Understanding the underlying cause and working with a professional is the best way to resolve this issue and create a safe and happy environment for everyone.
