Origin of Fox Terrier and Chihuahua mix

When was this hybrid dog breed created? To answer this question, first, let’s look into the origin of the parent breeds.

If we trace the earliest roots of Fox Terriers, this breed was initially developed in the latter part of the 1800s in the United Kingdom.

This breed was created for hunting purposes, particularly to flush foxes out of their hiding places which is why this breed is known as Fox Terriers in the first place.

Despite the fact that Fox Terriers are hunting dogs, they eventually became demanding family dogs.

On the other hand, Chihuahuas are a breed that originally comes from Mexico, and existing data shows that Chihuahuas were also first developed during the mid/ late 1800s.

Mexican merchants bred Chihuahuas as canine companions; however, some believe this breed was used for religious rituals by Aztec tribes around the 1500s.

However, the breed got its name after the city of Chihuahua in Mexico and became a well-known dog breed in the late 1800s. 

Although the parent breeds have plenty of information regarding their history and origin, there is limited information regarding their mixed breed.

This is a common issue regarding many hybrid dogs. Still, if we generally observe things, we can figure that Chi-Fox is a hybrid breed that has become popular in recent decades. 

The appearance of the Chihuahua mix and Fox Terrier

The appearance of the Chihuahua mix and Fox Terrier

Fox Terriers and Chihuahuas own unique appearances. Chi-Fox, which is their hybrid version, tends to have more or less physical characteristics from both parents.

Sometimes they may look more similar to a Fox Terrier, if not a Chihuahua, or they can also be the perfect amalgamation of both. 

Chi-Fox, or the Taco Terrier, is a tiny dog with an average weight of 3-6 pounds and a height of 6-9 inches. The coat of this hybrid breed significantly differs according to their parent’s coat.

Fox Terriers typically have a short coat that comes in two textures, smooth and wiry. Chihuahuas could have a smooth, medium, or long coat.

So the mixed version gets coats depending on the coat of their parents. However, usually, they get smooth, medium-length coats consisting of black, white, and tan colors.

Furthermore, this hybrid breed gets small pointy faces and relatively big ears, giving them an adorable look. Their eyes are pretty large and sharp. 

Toy Fox Terrier and Chihuahua mix

Both parent breeds of a Chi-Fox are considered small dogs, but comparatively, Fox Terriers are somewhat bigger than Chihuahuas.

It is essential to know that Fox Terriers can be further divided into different groups depending on their physique.

Toy Fox Terrier is one of those categories; as the name implies, it is the smallest of all types of Fox Terriers. So the blend of a Toy Fox Terrier and a Chihuahua creates a miniature hybrid dog. 

How big do the Fox Terrier and Chihuahua mix get?

As mentioned in the article, the cross between Fox Terriers and Chihuahuas results in a small dog. Chihuahuas are identified as one of the world’s most miniature dog breeds.

Fox Terriers are not as small as Chihuahuas; still, they are also known as a small dog breed. Their mixed breed typically weighs around 3-6 pounds and stands up to 6-9 inches tall. 

However, these measures could slightly differ due to some reasons. Genetics is the key factor determining the size of any dog, including Chi-Foxes.

While Chihuahuas are tiny dogs, Fox Terriers’ sizes vary as they come in different versions: Smooth Fox Terrier, Wire Fox Terrier, and Toy Fox Terrier.

So, according to parents, the usual size of this hybrid breed could change. Moreover, male Chi-Foxes are slightly bigger than their female counterparts.

Apart from the internal factors, external factors such as nutritional food and physical activities can also impact the growth of a Chi-Fox. 

The temperament of Taco Terriers (Chi-Foxes)

One of the most intriguing things about mixed breed dogs is their temperaments. We cannot precisely say what sort of temperaments and personality traits a hybrid dog breed gets.

Still, by generalizing their parents’ characters, we can roughly identify the nature of their mixed breed’s personality. 

Fox Terriers are active, friendly, lively, and alert dogs. On the other hand, Chihuahuas are fierce, courageous, and loving. Thanks to their parents, Chi-Foxes become super energetic and active dogs.

In fact, you will be less likely to get bored if you have one of these dogs as they are always full of liveliness. They mingle well with humans, especially children, as they match their energy levels.

Due to their small size, people often think Chi-Foxes are adorable and innocent dogs. They are undoubtedly lovable, but they aren’t naive dogs just because they are tiny in size.

Chi-Foxes are very courageous and alert dogs. They can also be fierce and mischievous sometimes. Nevertheless, as they are pretty smart, you will be able to manage troublesome behavior through proper and consistent training.

The overall personality makes them ideal family pets for experienced as well as first-time dog owners. 

How long do Chihuahua and Fox Terrier mixed dogs live?

How long do Chihuahua and Fox Terrier mixed dogs live?

Did you know that small dogs live longer than large dog breeds? Based on their genetic formation, giant dog breeds grow way faster than small ones.

So if you own a Chi-Fox or are planning to have one, the good news is this breed typically enjoys a longer life span than many dogs.

As small dog breeds, Fox Terriers and Chihuahuas have a longer life expectancy considerably; therefore, a healthy Chi-Fox usually enjoys a life span of 12-15 years. 

Keep in mind that this is only an average life span, meaning it could change for several reasons. If the puppies are coming from original bloodlines and you take good care of them, they will most probably get to live around 12 years or even more.

On the bright side, Chi-Foxes are healthy hybrid dogs. However, they can be vulnerable to some health complications they inherit from both parents, which could impact their overall life span.

While eye issues, arthritis, and bloating are the most common health issues among the breed, they can also get affected by more severe issues such as heart murmurs, hypoglycemia, and tracheal collapse.

Still, as mentioned, this breed is generally healthy, so as long as you pay attention to their dietary requirements, physical activity requirements, and health care, they will enjoy the maximum life span. 

How much do Chi-Fox Terrier puppies cost?

There isn’t a fixed price for the Fox Terrier and Chihuahua mix. However, compared to many hybrid dogs, Chi-Foxes are not highly expensive.

The average price range of this hybrid breed typically ranges from 300-1000 US dollars. Puppies that descend from reputed bloodlines and sold by reputed breeders can be relatively costly.

When you buy a Fox Terrier and Chihuahua mix puppy, ensure you get them from a certified breeder despite the price. 

Final thoughts about the Chi-Fox hybrid dog breed

Chi-Fox, or the Taco Terrier, is the cross between Fox Terriers and Chihuahuas. Chi-Foxes are absolute firecrackers because even though they are tiny, they will never fail to impress you with their outgoing, courageous, fierce, and loyal personalities.

Chi-Foxes get blended personality and physical traits from parents, and all together, they become unique and great family dogs.
