If a Boxer is not trained properly, he could become aggressive in new situations and around new people.

Some dogs are territorial or may feel a need to show their dominance. They may guard their toys, bed, and even people. They can also have food-aggression issues.

This problem is known as resource guarding and is a natural reaction in some dogs or can be something they develop over time if they are not cared for properly.

7. Past Trauma or Negative Experiences

Dogs that have been abused or have had past trauma and negative experiences may become aggressive in situations that remind them of these experiences.

8. Female-Female Aggression

Many Boxer females can become aggressive when other females are around. This is especially true if the female is in heat, has puppies, or is pregnant.

9. Overly Protective Nature

Boxers are guard dogs, and they tend to be overprotective by nature. This can something show up as aggression if they feel that their family or they themselves are being threatened.

10. High Prey Drive

How To Stop Boxer Aggression

If your Boxer is showing signs of aggression, the sooner you intervene, the more likely you are to stop the behavior before it gets out of hand. Here are some tips that can help.

Make sure your dog feels safe. Many dogs show aggression out of fear and confusion. Talk calmly to your dog when he starts to show signs of aggression to distract and calm him.

2. Use Positive Reinforcement

3. Get A Health Check

Sometimes dogs can act aggressively if they are in pain, don’t feel well, or have emotional or mental problems going on.

Make an appointment with your veterinarian to have a health problem ruled out or treated.

4. Socialize Them

Proper socialization is important for every dog breed and especially Boxers. Make sure your dog has plenty of socialization with other pets, animals, and people.

5. Professional Help
