Chihuahuas can be lovebugs to their favorite humans, but a war freak to other dogs. This breed is known to be dominant, and their territorial nature kicks in when there’s another canine around. They will try t0 dominate and fight the other dog, which makes it hard to raise them in a multi-canine setup. But with intensive socialization from puppyhood, it’s possible to introduce the best companion dog for Chihuahua.

Take note that raising another dog with a Chi isn’t an easy task. It entails rigorous training, socialization, and monitoring. You have to do the process right and pick the breed that suits your Chihuahua best. Below, I listed a few breeds that could be the perfect match for your dog.

Why do Chihuahuas find it hard to get along with other dogs?

It all boils down to their breed. Chihuahuas have a naturally territorial and dominant personality. They love snuggling with their favorite persons, but they are ready to jump up and fight when they sense danger.

And when we say danger, it could be the harmless presence of another dog, stranger, or even an object. Chihuahuas are a very sensitive bunch, so they tend to overreact to various stimuli.

Still, it doesn’t mean Chihuahuas can’t be raised with another dog. You just have to socialize and train the Chi the moment it steps into your home. This way, you can dampen its aggressive and territorial tendencies.

Aside from that, you also have to factor in the temperament of the specific Chihuahua you’re going to get from a breeder. If you got a puppy with aggressive parents, the pup would surely possess the same characteristics. This is why you should only deal with reliable breeders that focus on the form and personality of their dogs.

In addition to your dog’s personality, you also have to pick the right breed to pair with a Chi. Basically, you wouldn’t want to bring a breed with the same territorial nature. You should avoid breeds like Rottweiler, Doberman Pinscher, Giant Schnauzer, Puli, and Rhodesian Ridgeback, among others.

Lastly, you should choose the opposite gender of your Chihuahua. Same-sex dogs tend to have tension, especially between two female Chihuahuas.

Best companion dog for Chihuahua – Top 7 Options

While Chihuahuas can be difficult to raise with another dog, the choice of the breed will help increase your success rate. Here are some of the breeds you can consider for a second dog. Just note that many factors will affect these breeds’ compatibility with a Chi.

1. Another Chihuahua

If you don’t want to restart with another breed, you can get another Chihuahua to serve as a companion of your resident doggo. This way, you already know what to expect in terms of temperament and training. While each Chihuahua is different, you already have a headstart as an owner of the same kind.

The biggest advantage of getting another Chihuahua is the size. You won’t worry about the new dog crushing your little Chi. 

Just make sure that you get a second Chihuahua of the opposite gender. Many Chis prefer a Chihuahua-based pack, which will make it easier for you to perform the introduction.

Also, some pet owners don’t recommend getting littermates due to the so-called ‘littermate syndrome’. It’s said that littermates can experience sibling aggression and behavioral issues when sibling dogs are raised in one household.

This syndrome occurs after the dog’s first 10 weeks of life. Usually, this is the period when the Chihuahuas are placed in their new homes. While proof of this is mostly anecdotal, it doesn’t hurt to consider this aspect.

2. Shih Tzu

Shih Tzus are lovers, not hunters. They prefer to cuddle with their owners and are far from aggressive. They are also outgoing dogs with vibrant personalities, making them suitable for novice dog owners.

But how well do Shih Tzus go along with Chihuahuas? As an affectionate, dog-friendly, and laidback breed, Shih Tzus are unlikely to attack your little Chi. With proper training, Shih Tzus and Chihuahuas can get along pretty well.

Moreover, Shih Tzus will also benefit from the companionship of a Chihuahua due to their anxious nature. And like Chis, they also thrive in apartment living.

Tips in introducing another dog to a Chihuahua

It’s important to introduce the second to your Chihuahua slowly. Here are some tips that will guide you on the process:

✔️Start before bringing the new dog home

Even before the scheduled arrival of the new dog, you must prepare your Chihuahua. It helps a lot to desensitize and socialize your Chi to other dogs of the same or breed of what you’re getting. You can ask friends or family members who have pet dogs for this part.

Setting up a playdate or meeting with other dogs will prepare your Chihuahua for its life in a multi-canine household. If you don’t know anyone with dogs, the dog park will always come in handy. Just make sure that your Chi is leashed during the interaction.

Helping your Chihuahua become social with other dogs will make the introduction to a new pet much easier. You should also take the time to brush up with your pet’s obedience training.

✔️Introduce in a neutral space

Once the new pup is home, you should choose a common ground to make the interaction. Never bring the newcomer to your Chihuahua’s bed, feeding area, and other spots that the latter likes visiting. A separate room that your Chihuahua rarely visits is a good choice. This way, the resident Chi won’t feel threatened.

Above all, you should keep both dogs leashed and supervised. You can ask someone else to hold your Chihuahua’s leash while you handle the new dog.

✔️Keep it calm

Always use a calm tone in addressing both dogs. This is to prevent tension that could make the first interaction negative. Dogs can pick up on anxieties, which isn’t something you’d want to happen in the case of Chihuahuas.

If your Chihuahua is aggressive right off the bat, you should end the interaction. You can resume once your doggo is calmer.

✔️Let it rain treats!

Another way to make the introduction positive is to give your Chihuahua delicious treats while seeing the new dog. This will make your Chi associate the new pet with rewards. You need to repeat this every time you’ll schedule short meetings between the two dogs.

You should also observe the behavior of your Chihuahua. If it starts growling or becoming tensed, call its name and give a treat right away. This will help diffuse the situation.

✔️Give your Chihuahua extra attention

Chihuahuas can become extremely jealous when there’s a new pet at home. With this, you should focus more on your Chi than ever before. This will make your Chi realize that the new dog in the house isn’t a treat or a rival on your affection.

✔️Feed them separately

Since Chihuahuas are territorial, you should never feed them near the new dog. Instead, you should feed the two dogs in different rooms to avoid tension. Also, never let the new dog share your Chihuahua’s toys, bed, and other belongings.

Even letting the new pet touch these is a no-no. Dogs have a strong sense of smell, so your Chihuahua will easily know if someone else has been around. It’s not a good start for a protective and territorial breed.

✔️Start off-leash interactions

Once your Chihuahua has shown some level of acceptance of the new pet, you can now consider off-leash interactions. Still, you should be closely supervising the two canines to avoid dogfights.

It’s important to end each interaction, leashed or not, on a positive note. You shouldn’t wait for your Chihuahua to exhibit aggression before ending the session.
