Why Is My Yorkie So Aggressive With Other Dogs?

You love your Yorkie, but the struggle with their aggression towards other dogs is real. It’s natural to want to know why this is happening and what you can do about it. Keep reading to learn more about Yorkie aggression and what you can do to help your pup. 

Yorkies may become aggressive when they are afraid or feel threatened, are competing with another dog for a toy or treat, or any time if they are not fixed. You can address their aggressiveness by providing a stable and quiet environment at home, socializing them more often, and seeing a behavioralist.

Understanding Yorkie Aggression 

Although the Yorkshire Terrier is small, it’s a very brave and curious dog. If you want to address the aggression issue in your Yorkie properly, you must carefully analyze the behavioral problem your dog suffers. 

Let’s examine some reasons for your Yorkie’s aggressive attitude towards other dogs.

Fear or Insecurity

Fear and insecurity can often lead to aggression in Yorkie dogs. This is because they feel the need to protect themselves and their territory. 

If they perceive a threat, they may lash out to defend themselves. This can be a problem if the dog is not properly socialized and does not know how to interact with other animals or people.

Fearful dogs may also become withdrawn and restless, leading to further issues such as separation anxiety. It is important to remember that all dogs are different and will react differently to situations—for instance, some may be more prone to aggression than others. 

Still, it is important to provide all dogs with the proper training, socialization, and exercise to help them feel secure and prevent any problems from arising.

Threat or Territorial Behavior

Yorkie dogs are known for being fiercely loyal and protective of their family and home. However, this territorial behavior can sometimes lead to aggression, particularly if the dog feels threatened. 

Yorkies are alert and quick to respond to any perceived threat, whether a person or animal intruding on their territory. 

This instinctual behavior is often the root cause of aggression in Yorkies. To prevent territorial aggression, it’s important to socialize your dog early so that they learn to identify and trust people outside of your immediate family. 

Additionally, obedience training can help your dog better understand and       respond to your commands, even when feeling threatened. With patience and positive reinforcement, you can help Yorkies overcome their territorial instincts and live peacefully with people and animals inside and outside their homes.

Conflict Aggression

Yorkie dogs are small, adorable pets known for their friendly dispositions. However, they can sometimes exhibit aggression towards other dogs, particularly if they feel threatened or defensive. 

This type of aggression is often the result of conflict aggression, which occurs when two dogs compete for the same resource, such as food or attention. While conflict aggression is normal dog behavior, it can be problematic if it leads to regular fights or injures another dog. 

Fortunately, owners can do a few things to help prevent and manage conflict aggression in their Yorkies, and we’ll discuss that later. 


Generally, Yorkies come under the non-aggressive dog breed category. However, some dogs may display dominant attitudes toward other dogs if unsterilized. 

Alongside several other benefits like reducing the risk of the onset of certain diseases, sterilization of pets enable us to have fun games between same-sex specimens after the adaptation is complete.


Not all dogs that react by barking aggressively have intentions to “attack. ” Some of these dogs are completely happy and friendly when properly presented. A “reactive” dog is one with a regular habit of reacting to the presence of others.

Tips To Reduce Your Yorkie’s Aggression

For starters, you need to be able to point out the cause of your dog’s aggressive nature and the problem your dog is suffering. 

Below we have outlined some of these problems, but there are many more. 

For more insight into this situation, you must visit an ethologist or canine educator who understands animal behavior. They are the only people capable of giving you an accurate diagnosis and directions on how to work with your pet. 

In the meantime, while you’re waiting to contact an expert, you can begin addressing the problems your dog suffers in general by following these basic tips below :

Provide a Quiet and Stable Environment 

Your Yorkie should be part of a calm and quiet family so they can also learn to be calm. 

Remember that dogs pick behaviors from their families. If they observe their family members fighting or being aggressive, they start learning the behavioral pattern and acting aggressively. 

Avoid Scorning

A Yorkie with severe stress or anxiety shouldn’t be scorned. You always have to promote the desired behavior using a positive approach. Scorning could lead to added frustration in your dog, causing aggressive behavior.

Engage Your Dog in Socialization

You need to provide enough positive socialization experiences for your young Yorkie. This approach involves exposing them to different places, people, and friendly dogs in a positive way, to teach them that not all new things are harmful.

Introduce Mental and Physical Stimulation

It is essential to provide enough mental and physical stimulation to retrain your aggressive Yorkie. 

Activities like puzzle toys, obedience training, and daily runs/walks are the best way to diagnose dog aggression or animal behavior. A dog is happier when tired! This approach can reduce the competition for resources.

You must walk with your Yorkie for at least 90 minutes daily, divided between 2 and 3 complete walks. You must also analyze common mistakes when walking with your dog and avoid them.

Avoid the Small Cute Dog Syndrome

Like several other small dog breeds, Yorkies are very susceptible to developmental issues because of their small size. Most dog owners tend to downplay these issues because they feel they’re cute.

It is crucial to engage your Yorkie in socialization exercises during the early stages of a dog’s life. This will provide them with direction on the things that are right and wrong.

Do not spare your dog when it displays aggressive behavior because you feel it looks cute when it behaves in such a manner. Ensure you start your Yorkie off on the right path, and you’ll both have a pleasant future together.

Consult a Veterinary Behaviourist

Finally, contact a certified applied animal behaviorist if you’re having issues managing your dog’s aggressiveness or unwanted behavior.


You’re not alone if you have a Yorkie that’s aggressive towards other dogs. There are a few possible explanations for this behavior and a few things you can do to help your pup feel more comfortable around other animals. 

With patience and positive reinforcement, you can help your Yorkie overcome its aggression and enjoy spending time with other dogs. Thanks for reading!
