Origin of Rat Terrier and Chihuahua mix

Although Rat-Chas gained popularity over the past few decades, the origins of the parent breeds can be traced back to the 19th century.

If we start with Rat Terriers, this breed developed in the early 1920s in the United Kingdom. In the early stages, Rat Terriers were bred as hunting dogs, but eventually, the characteristics of this breed changed, and they became family dogs rather than hunting dogs.

On the other hand, Chihuahuas were bred in the late 1800s or early 1900s in Mexico, yet some believe their roots can be traced way before.

However, they became a demanded breed in the 19th century. Fun fact, Chihuahuas were named after the state of Chihuahua, which is the largest of all states in Mexico.

When it comes to the origin of the Rat Terrier and Chihuahua mix, the date of origin is not precise.

Most likely, this crossbreed was developed to create dogs with smaller body sizes and prominent personalities, and in recent days Rat-Cha is a famous hybrid dog.

The appearance of the Rat Terrier and Chihuahua mix

Hybrid dogs sometimes get more physical traits from one parent over the other if not, they could be a fair blend of both parents, which applies to Rat-Chas as well. Nonetheless, Rat-Chas are undeniably adorable-looking dogs.

The appearance of the Rat Terrier and Chihuahua mix

Rat-Chas are considered small-sized dogs. They have an approximate weight of 10-15 pounds and a height of 10-14 inches.

Rat-Chas could have short to medium lengthed fur that is straight and glossy. The coat is typically a combination of two to three colors, including white, black, brown, fawn, red, and gray.

These dogs have round dark eyes giving them a sharp look. Their faces are pretty small, and compared to a Rat-Cha’s face size, they have relatively large pricked ears, which gives them a more adorable appearance. 

How big do Rat Terrier and Chihuahua mix get?

Since hybrid dogs inherit genes from two different breeds, one cannot pinpoint how big they would exactly grow. But we can focus on the possibilities.

Rat Terriers are somewhat bigger than Chihuahuas, yet both breeds are typically considered small-made dogs.

Therefore Rat-Chas also clearly belong to the same category. But if the dog possesses more genes from one parent than the other, you can see differences in their sizes.

A Rat-Cha grows up until 18 months, and a full-grown healthy Rat-Cha could weigh around 12 pounds and stand tall up to 12 inches.

Always keep in your mind that genes are the primary determinant of the growth of a Rat-Cha.

However, some external factors such as food and exercise can also impact their growth to a reasonable extent.

The temperament of Rat Terrier and Chihuahua mix

Dogs have varying temperaments. Imagine the combination of two dog personalities; it would be intriguing, wouldn’t it? Rat-Chas are certainly dogs full of character.

Like any other hybrid dog, Rat-Chas could have more personality traits from one parent or perfectly balanced personality traits from both. 

If we separately analyze the temperaments of parent breeds, you can find some similarities between them and differences.

Overall, Rat-Chas tend to be lively, energetic, alert, loyal, and affectionate dogs. With all the positive behavioral traits, sometimes they can be sneaky and a little aggressive too.

Neither Rat Terriers nor Chihuahuas will be the most aggressive dogs you will meet, but they have a bit of aggressiveness embedded in them, and that could make their hybrid version aggressive.

On top of it, since Rat Terriers naturally inherit prey instinct, Rat-Chas could also get it from the Rat Terriers. When Rat-Chas have both aggressiveness and prey drive, they will likely act stubbornly.

But do not worry about this because these dogs are also intelligent and devoted. If you train them and socialize them from a young age, they will not end up aggressive. 

How long do Rat Terrier and Chihuahua mix dogs live?

We all would love our pet dogs to live as long as possible with us. The good news, Rat-Chas has an incredible average life span around 12-14 years.

Based on their genetics, it is proven that small dogs typically live longer than humongous ones. Rat-Chas enjoy a long life span compared to many other dog breeds.

Rat-Chas are generally considered healthy dogs, but that doesn’t mean they do not face health complexities at all.

However, if you are attentive enough to a Rat-Cha’s general health, they will likely live 16-18 years. That is a very long life span for a dog. 

How much do Rat Terrier and Chihuahua mix puppies cost?

Compared to many other hybrid dogs, Rat-Chas are not the most expensive ones out there.

How much do Rat Terrier and Chihuahua mix puppies cost?

Although you cannot give a fixed price for a Rat-Cha pup, you will usually get to buy them for 400-500 US Dollars. Just because Rat-Chas are relatively cheap, don’t buy them without a background check.

To ensure that pups are from purebred Rat Terriers and Chihuahuas, always purchase puppies from a reputed and certified breeder. Depending on the parents’ bloodline, the price of a Rat-Cha may vary.

Maintenance tips for Rat Terrier and Chihuahua mix

How hard is it to maintain a Rat-Cha? If you know the essential facts about their maintenance, it will not be complex.

So let’s see what you should know regarding the general care and other related sectors of this breed.

  • Grooming 

Rat-Chas might not be low-maintenance dogs, especially if they have a coat similar to a Chihuahua, but they are easy to maintain.

Usually, Rat-Chas are considered moderate shedders, and to maintain the coat, you must pursue a consistent grooming routine.

You don’t have to bathe them frequently, but you should brush them at least once a week. It will help to maintain the coat’s glossiness, remove excess hair, and control shedding.

Rat-Chas are highly prone to dental issues; therefore, you must brush their teeth a couple of times a week.

Small dogs could quickly gather tartar, leading to cavities and other dental issues, so you cannot ignore their oral hygiene. It is also essential to check their ears and trim their nails occasionally. 

  • Food and exercise requirements 

As much attention as you pay to their grooming and care, you should also pay good attention to their food requirements because a dog’s diet plays a pivotal role in ensuring its health and well-being.

Rat-Chas do not need vast quantities of food. One cup of food per day would be sufficient to meet their basic food requirements. But it is essential to provide them with quality and nutritional food.

A balanced meal of a Rat-Cha should contain more proteins and fewer calories. Speaking of physical activities, Rat-Chas do not need intense exercises, but exercise is a must as they have high energy levels.

Taking them for a quick stroll for 15 minutes would help them burn off their excess energy and stay fit.

  • General health

Rat-Chas are considered healthy dogs, but like any other dog, they also inherit health complexities from parent breeds.

Some typical health issues that you can notice in Rat-Chas are dental issues, cataracts, glaucoma, alopecia, and atopy.

These conditions tend to be minor health complications, but as soon as you see frequent and sudden changes in your Rat-Cha’s behavior, it is advisable to take them to a vet.

Rat-Chas could also go through severe health conditions, including collapsed trachea, hydrocephalus, diabetes, and hyperthyroidism.

So pay close attention to your Rat-Cha’s behavior and do occasional veterinary check-ups.
