Chihuahua Terrier Mix Highlights

  • When considering a Chihuahua Terrier Mix, one must bear in mind the diversity of size, color and temperament that may be exhibited due to the numerous breeds of Terriers and a small number of variations in Chihuahuas.
  • As is typical of Chihuahua Terrier Mix dogs, they are known for having high energy levels and need regular exercise to prevent them from becoming hyperactive.
  • Excessive barking is often an issue with toy breeds such as Chihuahua Terriers, so proper training of the command ‘speak and quiet’ should be administered.
  • It is essential to provide mental stimulation daily to all Chihuahua Terrier Mixes; particularly the Rat Terrier.
  • Chihuahua Terrier Mixes can be contented in an adult-only household or with older children.
  • Owing to their petite proportions, they do not require abundant sustenance. They will only need roughly one cup of kibble daily.
  • Cross-breeding of Chihuahuas and Terriers has beneficial outcomes in terms of genetic health compared to purebreds; yet, like any other breed, some common ailments are known to affect this mixed breed.


The likelihood of natural crossbreeding between Chihuahuas and Terriers is substantial; however, there has been a deliberate crossing of these breeds over the last few decades initiated by designer breeders. As public interest in hybrid dogs surged, breeders began combining different varieties of Terriers with Chihuahuas.


It is widely thought that the Chihuahua breed traces its lineage back to Mayan times, with their direct descendants being the Techichi. That’s right; the Mayan people kept a distinct type of canine, known as Techichis, which was renowned for its diminutive size.

The Toltecs later conquered the Mayans and were the first to begin the domestication of Techichis, thus keeping them as companion dogs. The Toltecs saw the Techichis as more than just animals; they utilized them for religious practices, rituals, sustenance, and friendship. Some members of this culture even held the belief that they were divine.

Furthermore, Ancient Toltec, Aztec, and Mayan manuscripts and drawings discovered in tombs and pyramids depict the Techichi dog breed.

The Techichi canine breed was first encountered in 1850 during a survey of the Mexican state of Chihuahua, near archaeological sites constructed by the former Aztec ruler Montezuma. When explorers ventured to the newly discovered world, Techichi mated with a canine brought along by those sailing from their home countries. This ultimately led to the evolution of what we now recognize as the Chihuahua breed.


The contemporary terrier breeds are derived from hunting breeds native to Europe. Compared to hounds, terriers represent a comparatively recent development in the history of canine domestication. Almost all initial terrier breeds were domesticated primarily to eliminate pests, particularly small mammals and foxes. A preference was held for those breeds with strong instinctive drives and intense determination.

The word ‘terrier’ is derived from the Latin word ‘terra’, signifying the earth and ground. It reflects the primary activity these dogs are trained for: chasing small animals into their burrows or dens underground.

Over the years, terriers have evolved to be of a particular size and form in light of new hardships. This breed is well-known for its determination and fearlessness. Terrier breeds inherently possess the instinctual tendency to pursue prey and aggressively take hold of it. This instinct expresses itself within a domestic setting in terms of mischievousness, playfulness and impulsivity at times.

Chihuahua Terrier Mix Size

Chihuahuas have a notoriously distinct appearance, marked by their diminutive frames and large, soulful eyes. They are usually no more than 6 pounds in weight with perked ears resembling that of a fox.

The size of a Chihuahua Terrier mix will vary depending upon which type of terrier is its parent. Various sizes of terriers exist, thus imparting visible differences in size within the mixed breed. 

Chihuahua Terrier Mix Colors

It is unlikely that a Chihuahua Terrier mix will maintain the conventional white coat associated with the Chihuahua breed. Depending on genetic traits inherited by parent breeds, brown and white patches will appear.


The coats of Chihuahuas are typically characterized as having a soft texture. In contrast, some Terrier breeds may have a more rough coat that will likely be inherited by their offspring.


The character of a Chihuahua-Terrier mix is contingent upon the exact breed of Terrier, though it is generally acknowledged that Terriers possess unparalleled levels of energy and determination as well as being highly loyal. 

These animals have high intelligence and are driven to hunt, yet they tend not to be ideal pet for families with small children due to their limited capacity for tolerance.

These animals may appear cuddly and cute, but they are not suitable for households where the owner is often absent or working. Separation anxiety can become an issue because of their social nature and lack of independence. Unfortunately, this means that leaving them home alone for extended periods can lead to behavioral problems and other health issues.

Ultimately, it is unpredictable what kind of canine you acquire; yet, if you know which breed of Terrier comprises one side of the pup’s genealogy, you will understand what to expect.

The following are examples of Chihuahua Terrier Mix breeds, accompanied by the characteristics most owners typically find accurate.

Chihuahua Yorkshire Terrier Mix

Cross-bred puppies between Chihuahua and Yorkshire Terriers, commonly referred to as Chorkies, are renowned for their immense cuteness. Yorkies typically hold a regal demeanor that is difficult to imagine coming from such small creatures.

Certain Chihuahua-Yorkshire Terrier canines demonstrate traits most clearly delineated from their Yorkshire Terrier side, while others show a more distinct nature from the Chihuahua breed. One can’t predict the physical characteristics of a Chorkie until they are grown, as with any first-generation cross. Nevertheless, litters may contain puppies that exhibit traits from both parent breeds.

Chihuahua Bull Terrier Mix

It is not surprising that the individual responsible for naming new dog breeds and hybrids decided to give this combination “Bullhuahua”, a rather complex name. This canine creation, however, truly stands out as a remarkable animal.

Bull Terriers are known to be strong, loyal and affectionate companions that stay close to their human families. They do well with small children and require little grooming due to their low shedding levels. 

However, it is well-documented that the Bullhuahua often exhibits a lack of intelligence and requires an extended period to be effectively house-trained. Therefore, one must possess abundant patience when caring for one of these animals.

The impressive physical strength of this Chihuahua Bull Terrier Mix breed makes it the most powerful of its combinations. Consequently, any owner of such an animal must be able to manage it effectively.

Chihuahua Cairn Terrier Mix

Although a Chihuahua Cairn Terrier Mix may appear unassuming and harmless, it is important to remember that they should not be underestimated.

This breed is known to be very protective of its owners and makes a great guard dog, despite its small size.

Once introduced to its new home and trained accordingly, his Chihuahua Cairn Terrier Mix will be a loyal family member. As with all Terriers, their physical and mental needs must be met through regular exercise and stimulation.

Chihuahua Rat Terrier Mix

The Rat Terrier possesses similar physical characteristics as the Chihuahua, including large ears, round eyes and prominent facial features.

These canines are particularly loyal to their owners and fiercely protective of them; therefore, they do not readily welcome unfamiliar individuals and may be prone to snap at those they do not recognize.

Chihuahua Rat Terrier Mix dogs have fragile bodies, so they should be treated with great care. Nonetheless, they possess tremendous affection for their owners and take pleasure in cuddling up close to them, especially under blankets that provide warmth.

Chihuahua Jack Russell Terrier Mix

The Chihuahua Jack Russell Terrier Mix (Jack Chi) is the ideal size for a small house or apartment and is an excellent mixed breed for those who desire a dog that requires minimal upkeep. Their charming personalities make them great companions, and their intelligence allows them to be easily trained.

Although they take up less room than other dogs, that does not reduce the care and attention required. Jack Chi dogs are renowned for their need for regular mental stimulation and physical activity; their Jack Russell ancestry makes them prone to impulsiveness, leading them to pursue anything that catches their attention.

It is critical to provide early and ongoing training for these dogs; otherwise, if left unattended or without any stimulation, their natural inclination is to be disruptive due to boredom.


For certain purebred puppies, the delimited gene pool has resulted in health problems. Crossbreeding may alleviate some of these issues; however, other genetic ailments could potentially be inherited from the parents.

When selecting a Chihuahua x terrier puppy, it is important to bear in mind all potential medical ailments associated with their breeding lines, such as Lens Luxation, Tracheal Collapse, Heart Disease, and Patellar Luxation.


Did you know that these loyal pups can live up to 12 to 15 years? 

With proper care and nutrition, a Chihuahua Terrier Mix could become your family’s most trusted friend and companion until they reach their golden years. This long life span allows them to form close bonds with their owners and develop unbelievable loyalty.


If you are considering providing a home for these puppies, be aware that they will need adequate outdoor space to expend their energy; however, as they tend to stay on the smaller side, they do not require as much room to roam as larger dogs.

These canines possess low stature and advanced cognitive abilities, so they prove highly adept at escaping enclosures. Owners of such animals must survey their property for slight openings and ensure that each is properly closed off.

Owing to their diminutive nature, these animals are often trained in crates or placed in secure rooms where they can remain safe. As their behaviour may sometimes border on aggression and hyperactivity, they are not recommended to be left unattended with other animals.


The rule of thumb is to provide any Chihuahua-crossed breed with dry kibble in their diet. Small canines are vulnerable to dental overcrowding, and dry kibble consumption helps maintain proper dental hygiene. You can feed them a combination of wet and dry food and periodic incorporation of freeze-dried or raw ingredients. Nevertheless, kibble should consistently form the basis of their daily diet.

How one should groom this mixed breed dog largely depends on the particular kind of inherited coat. In some cases, its coat may be short and require minimal brushing, with only one or two sessions per week.

Others, like the Chihuahua Yorkshire Terrier Mix, require dedicated care as their coats tend to be longer and softer, necessitating daily or bi-daily grooming. One should anticipate that considerable time must be devoted to the upkeep of such a pup.

Chihuahua Terrier Mix Puppies

As with adult dogs, Chihuahua Terrier Mix puppies are notably energetic. Newborn puppies require extra vigilance due to their delicate bone structure and the presence of a molera, an open gap over their head. Once the puppies have grown and reached adulthood, the molera will gradually close. Until then, however, it is paramount to exercise extreme caution during handling as dropping them can result in grave consequences.

From a young age, expose your Chihuahua Terrier pup to as much socialization as possible with people and dogs and different conditions. This experience cultivates confidence within the puppy, which will carry over into their adulthood.

Children and Other Pets

Due to their assertive temperaments, the Chihuahua Terrier Mix is not recommended for families with young children. It is better suited for an active adult-only household that can provide adequate stimulation and exercise.

More importantly, the Chihuahua Terrier Mix has the potential for aggression towards other animals in the home; therefore, it is important to provide an environment conducive to socialization so that it can learn there is no reason to perceive other dogs as a threat.
