When people think about chihuahuas, they often picture the more common short-haired ( or smooth coat) type.

Long haired chihuahuas deserve some recognition too! They have all the spunk and energy of short haired chihuahuas, and they come with extra fluff. What’s not to like?

Long Haired Chihuahua Facts

Many people may wonder how long haired chihuahuas differ from other chihuahuas (besides the coat length, obviously).

It turns out that they are similar in many ways, but long haired chihuahuas have several interesting characteristics that separate them from the rest of the pack.

The long haired chihuahua is actually considered an ancient dog breed. They are known for their enormous hearts and are very loyal to those they love. Despite being one of the smallest dogs in the world, they are an energetic and spunky dog breed that can take care of themselves and their owners.

Check out our main post that showcases all our Chihuahua fact articles!


Don’t be fooled by what looks like a cozy coat of fur! Long haired chihuahuas, like all chihuahuas, do not tolerate cold weather well.

They originated in a hot climate, after all. Long haired chihuahuas, being very small, lose body heat more easily than bigger pets. If you own a long haired chihuahua, make sure to keep her warm, especially if you live in a cold area.

Many chihuahua owners like to dress up their pups in cute sweaters. Chihuahuas also tend to enjoy blankets and will burrow underneath them.

Don’t keep your long haired chihuahua outside for too long on a cold day, and watch her closely to make sure she isn’t shivering. Even though she has more hair than her short hair counterpart, she can be just as sensitive to the cold.


Though long haired chihuahuas do not do well in the cold, that doesn’t mean they are fine in the summer sun.

They also tend to struggle in hot weather. It is important to make sure these dogs are in a comfortable, warm environment as much as possible. Excessive panting can be a sign that they are getting overheated.


Due to genetic factors, boy chis tend to be blessed with more luxurious coats than the girl chihuahuas. There might be some female long haired chihuahuas out there with longer fur than some male long haired chihuahuas. However, on average, the males have longer, fluffier hair.


This means a couple of different things. One is that two short haired chihuahuas can actually have long haired puppies.

For that to happen, both short haired parents must be carriers of the gene for long hair.

Both short hair and long hair puppies can be born in the same litter.

The other thing is that because long hair is a recessive trait, long haired chihuahuas are less common than short haired chihuahuas.

However, if long haired chihuahuas were to have a boom in popularity, breeders might respond by producing more long haired puppies. Long haired puppies are much more likely if both of the chihuahua parents have long fur.

The fur can take a really long time to grow! Some long haired chihuahuas don’t grow their full coats until they are almost two years old. Others have a full-fledged coat of fur at a younger age.


Both types of chihuahuas belong to the same breed and have most of the same general characteristics.

Long haired chihuahuas simply have a genetic variation that gives them longer, fluffier fur.

A common misconception is that long haired chihuahuas have a difference in personality. This is not true at all! Long haired chihuahuas generally have the same range of personality types as short haired chihuahuas.

Of course, every long haired chihuahua has its own personality. However, this is shaped by the individual dog’s life experiences and genetics.

The personalities of the chihuahua’s parents can play a role, and so can socialization as a puppy. It has nothing to do with the length of the dog’s fur.


brushing long hair Chihuahua

Brushing out their long coats removes dirt that builds up in their fur, and it prevents tangles and matting.

These are problems that the owners of short haired chihuahuas don’t have to worry about so much, but a long haired chihuahua dog owner must be conscious of them!

A lot of people forget about brushing the dog’s tail. However, it is especially important to brush the tail because the long tendrils of tail hair can easily pick up dirt and dust particles.

The owners of a long haired chihuahua should inspect and brush their dog’s tail a few times a week.

Your long hair chi may need to be bathed more often than a short hair chi. Being low to the ground, he may pick up mud or other debris. Or he may get poop or pee stuck in his hair. Ugh!

If you fail to brush your long hair chihuahua, you will find that its hair can become matted very quickly. When brushing, try using a metal slicker brush or comb that will easily go through their long hair with no problem.

It may also be helpful to know that this dog breed may also shed their hair in clumps instead of shedding individual hairs. The bright side? It makes it that much easier to clean up after they shed since it is all clumped together.

Finally, you do not need to bathe your small dog a lot because doing so can easily dry out their skin. So, unless they really need a bath because they are dirty, it should be avoided. If you must bathe them, avoid getting any water in their ears.


The average lifespan for the long haired chihuahua is approximately 15 to 20 years.

Backyard breeders, also known as puppy mills, are said to be responsible for the long haired Chi. The chihuahua puppy has been extremely popular in the past for its popularity as well as fashion status. Backyard breeders are those known for breeding a chihuahua puppy for profit rather than pedigree. This ultimately means that health and adherence to any breed standards are also thrown out the window when we see this kind of chihuahua breeder.

A purebred long haired chihuahua can cost as much as $1,500. They are usually fully grown by 18 months of age. The male and female chi puppy can grow to be around 7 inches in height and approximately 4 pounds in weight.

However, the long haired chihuahua puppy also comes in different sizes, so they might not always conform to the growth outlines we have mentioned – as long as they match the breed standard.


Chihuahuas can be gentle and loving pets and are fiercely protective of their owners. However, when it comes to other animals, they prefer their own breed. This is why socialization at a young age is recommended. It helps them get along with other pets and children in the home.


One of the biggest health concerns for the chihuahua breed is known as Patellar Luxation. This condition greatly impacts their ability to move their knee joints correctly, and it can ultimately lead to the development of osteoarthritis.

Luxating patella is a common condition in dogs, especially those who fall into the category of small and miniature toy dog breeds. You can usually see signs of this condition between 4 and 6 months of age.

However, a luxating patella can also be treated with medication or surgery in some cases, depending on its severity.

Long haired chihuahuas can also develop other serious health conditions, including pulmonic stenosis, hydrocephalus, a heart murmur, and keratoconjunctivitis sicca.

At the end of the day, long haired chihuahuas and short haired chihuahuas are two different versions of the same breed of dog. As such, they share many of the same characteristics.

Despite the similarities, long haired chihuahuas have their own set of interesting features and challenges that a chihuahua dog owner and enthusiast should be aware of.

My Bella (a 13-year old, long-haired Chihuahua) sees the vet for her Wellness Check-Up once a year. She is also tested for Heartworm once a year, although she gets a Heartworm injection twice a year. She receives an injection because she will not eat the Heartworm chew and I never found any way to disguise it in food. If your dogs are healthy, I think every six months is rather extreme.

I agree Marguerite, it does seem rather extreme.

Thank you for writing this! I have a chihuahua/jack russell mix and I think he is a long-haired chihuahua now because he has puffy fur like a male long-haired chi.

You're welcome Danielle.

My Vet sends me a reminder when my dogs are due for their 6 month wellness check, but I only take mine once a year unless they are having problems. I have no problem getting their heartworm meds even though I only take them once a year. It's only recommended.


Thursday 24th of June 2021

Mine won't renew the heartworm meds without a heartworm test so I'm stuck going every 6 months.

I recently lost my Grettle Mae to mast cell cancer. She was only 7. I was told she was a pomapoo when I got her, but my vet thought she was a long haired chi. And when I took the time after she passed to look at pictures, I was looking at my Grettle. Although when she went to the rainbow Bridge I said I wouldn't get another dog, I had a hole in my heart. Honestly, if my vet had told me Grettle was a chimp, that's what I would have looked for! A couple of weeks ago I got a chi that is so cute and fluffy. Both of her parents were short haired, but she definely has long hair. She is so tiny and perfect. I have other dogs so I want to stay impartial, but I know she will be a little princess and spoiled by all. There really are no words to express how happy she had made me already. Thank you for sharing your stories and knowledge about long haired chihuahuas. I feel like a first time chi owner since I didn't know my perfect girl that passed was really a chi.
