Why Is My Dog Aggressive Towards Some Dogs But Not Others

You walk into your backyard and see your dog happily playing fetch with another dog. But as soon as you turn your back, your dog charges at another dog viciously barking and growling. What’s going on?

Many owners wonder why their dogs behave aggressively towards certain other animals – especially if they’ve had no prior interactions with them. Some possible explanations include genetics, environment, and training. In this article, we’ll explore each of these factors in greater detail to help you better understand why your dog may be aggressive towards some dogs but not others.

What Causes Aggression in Dogs?

There are many possible causes of aggression in dogs, but some of the most common are:

-Behavioral problems that are causing frustration for the dog
-Panic and fear reactions when a dog is around other animals or people it is unfamiliar with
-Physical health problems, such as tumors or arthritis, that are causing pain or discomfort
-Environmental factors, such as changes in family dynamics or new additions to the home that the dog perceives as a threat
-Lack of socialization and training

What to Do If Your Dog is Aggressive Toward Other Pets

If you have a dog that is aggressive towards other dogs, there are a few things you can do to try and fix the problem. First, try to find out why the dog is aggressive. Is the dog territorial? Is the dog fearful or anxious? Are there certain smells or sounds that set off the dog’s aggression? Once you know the reasons behind the aggression, you can start to address them. You may need to keep your dog confined to specific areas of the home or yard, avoid giving it certain foods or toys, or use a training collar or leash when interacting with other dogs.

If none of these tactics work, you may need to consider getting your dog tested for anxiety or aggression disorders. These disorders can be treated with medication and/or behavioral therapy. If your dog is already diagnosed with one of these disorders, you will likely need to take additional steps to help him learn how to deal with other dogs safely.

How Can I Keep My Dog Safe from Other Dogs?

There are a few things you can do to make sure your dog is safe from other dogs. Make sure your dog has been socialized from a young age, and that he is comfortable around other animals. If your dog is aggressive towards other dogs, make sure he is supervised when he is around them. You can also try to train your dog to be calm around other dogs by rewarding him with treats or toys when he behaves calmly.


There could be a number of reasons why your dog is aggressive towards one dog but not another. Some dogs might simply be more dominant than others and may feel threatened by any other dog that comes close. Other times, it could be that the aggressive behavior is learned from the owner or another family member and the dog has picked up on this behavior. In any case, it’s important to take your dog for a walk so that he can get away from any other dogs and calm down. If you notice that his aggression is becoming more frequent, it might be worth consulting a vet to see if there are any underlying medical issues that need to be addressed.
