But there is still a lot more about them you should know. In this post, we will be giving you all that info.

We will also discuss the Rat-cha grooming routine, including how to manage its shedding. We wrap up the post with a few FAQs to ensure you have a detailed understanding of what Ratchis are all about.
What Does A Chihuahua Rat Terrier Look Like?

The Rat-Cha is a common โdesignerโ dog. It is a crossbreed between the Chihuahua and the purebred American Rat Terrier. These beautiful canines were introduced in 1990. 30 years down the line, they have established themselves as some of the most dominant crossbreeds in the world today.
Physical Attributes
The Rat Terrier Chihuahuas are typically small in stature. These little canine buddies will weigh between 12 to 25 lbs on average. Rat-Chis also donโt grow that tall. Typically, they stand between 12 and 18 inches at shoulder level.
They also have large, erect, and somewhat triangular-shaped ears that protrude way over their small heads. These large ears give Rat-Chis outstanding awareness and they tend to be extremely alert at all times. These cute little four-legged buddies also have a relatively higher life expectancy. Rat-Chis live for between 10 to 15 years at most.
The Rat-Chaโs Personality
The Rat-Cha is a high-energy and frisky pooch. The dogs are extremely confident, playful, and very welcoming too. Itโs however not uncommon for Rat-Chas to show aggression at first. But after a few days of socialization, they cool off easily.
Nonetheless, letโs not forget that these cute cross breeds have a little terrier in them. In that case, they often get alarmed in the presence of strangers. But they are not nearly as aggressive as the real terriers. The Rat-Cha is also sometimes referred to as the Rat-Chi.
What Is The Lifespan Of A Rat Terrier Chihuahua? Health Problems Of A Ratcha

As we have already indicated above, a Rat Terrier Chihuahua lives for 10 to 15 years. The Rat-Cha is generally a very healthy dog. However, the pooches are susceptible to certain health conditions. Here are two of the main ones to keep in mind.
Patellar Luxation
Patellar luxation is characterized by the dislocation of the kneecaps. It is normally detectable within the first 6 months of the poochโs life. If not properly treated, patellar luxation will significantly affect your dogโs mobility and activity levels.
Hip Dysplasia
Hip dysplasia is also very common with Rat Terriers Chihuahuas. The disease normally affects the dogโs hip joints and may significantly limit mobility too. Hip dysplasia is normally inherited from dog to dog. But it can be accelerated by environmental factors including the poochโs health and age.
Joint degeneration is however inevitable. Although we want our little Rat Terrier Chihuahuas to jump up and down all the time, as they age, they may no longer be able to do so.
Joint Treatment For Your Rat-Cha
The great news is that some supplements can help with these joint-related conditions. Doggie Dailies Glucosamine is one of them. This supplement contains a rich amount of glucosamine, along with MSM (methylsulfonylmethane), chondroitin, and turmeric in its formulation, that can alleviate joint health.
All these ingredients contain anti-inflammatory properties. They are used to enhance overall joint health, including joint pain relief. Although these dog chews are marketed as a supplement for older dogs, the product will also work great for pooches with joint injuries.

What Is The Temperament Of A Rat Chihuahua Terrier Mix? Temperament Of A Ratcha
Ratchis are naturally very attentive and aware of their surroundings. This is because of their large ears and also because of their personality. The pooches are also very active and playful. This makes them great family dogs.
Are Rat-Chis Aggressive?
Rat terrier Chihuahuas may show aggressive behavior towards strangers. Keep in mind that these beautiful four-legged canines are half terrier. And as we know by now, terriers are aggressive and territorial.
But Ratchis are not nearly as aggressive as the real terriers. I guess the cute and laid-back personality of the little Chihuahua in them balances everything out.
The most important thing for Ratchis is socialization. These Rat-Chis are affectionate once they get to know the person. So, if they growl at you for the first time, just give it time. The pooch will soon come around.
How To Keep Your Rat Terrier Chihuahua Active?
Letโs be honest, you are not going to be there all the time to play with your active rat-cha. It is, therefore, a great idea to get the pooches a toy to keep them busy. There is nothing more fulfilling for a dog owner than spoiling these furry buddies with toys and treats.

Do Rat Terrier Chihuahua Mix Shed?
Ratchis are relatively low-maintenance dogs. Unlike some breeds like Pugs and German Shepherds โ the very same breed the 46th POTUS has, rat terrier Chihuahuas are moderate shedders. Brushing the pooch at least once every week should be enough to get rid of dead or excess loose hair.
However, it is important to note that Chihuahuas rat terriers tend to shed more hair during the summer. It is therefore advisable to expand the grooming routine during these hot months. Brushing twice a week during summer will go a long way in keeping loose and dead hair away.
What Determines Shedding In Dogs?

Shedding is a completely natural process for dogs. However, the frequency and pace of shedding vary from breed to breed. Additionally, shedding may also be influenced by the seasons. For instance, during the cold winter months, dogs tend to develop heavy thick coats to protect themselves against the cold. At the onset of spring, where temperatures are relatively higher, the pooches will start to shed off excessive hair. This will continue well into the summer.
In some cases, excessive shedding may be a sign of underlying health issues. Letโs say for example you own a rat-cha or any other breeds that donโt typically shed that much. Always pay attention to the poochโs shedding rates or frequency. If they are shedding too much hair, have them checked just to be on the safe side.
Grooming Tips Of A Ratcha
Ratchis normally require two things as far as grooming goes. This includes brushing their coats regularly and dental care. Getting the pooch a nice chew toy will help keep tartar and bad odors away. Consider brushing the dogโs teeth too for proper dental hygiene.
Grooming The Coat
Secondly, you also need to take care of the Rat-Chaโs coat. So, as we have noted above, rat terrier Chihuahuas require moderate grooming. This is because these lovely four-legged buddies donโt shed that much. Typically, a grooming routine for a rat-cha will involve brushing the coat once a week. Make sure you expand brushing to twice a week during spring and summer.
Are there Any Specific Grooming Brushes I Should Use?
It is important to make sure you are using the right grooming tools for your furry buddy. Brushing the coat is supposed to be one of the most enjoyable experiences for your little pooch. But if you donโt invest in quality grooming brushes, then your four-legged friend will always feel agitated and anxious during grooming sessions.
