How Long do Chihuahua Live ?

The Chihuahua dog is the smallest breed in the world. They are known for their alert expression and long, silky coat. The average height of a male Chihuahua is 6 inches (15 cm) at the shoulder, while females are slightly smaller at 5-7 inches (13-18 cm). Their weight ranges from 2 to 6 pounds (0.9 to 2.7 kg), making them one of the lightest breeds around!

This article will explore how long chihuahuas live on average and what factors may affect this lifespan.

It is important to remember that each dog is an individual with different lifestyles, which can have a significant impact on their life expectancy. Some dogs enjoy long lives while others suffer from chronic diseases and die young, so there are many factors involved in determining whether your Chihuahua will live for 8 years or 18 years.

To give you a rough idea, the average lifespan of Chihuahuas is around 14-16 years. This falls into the category of “middle aged,” according to veterinarians, but it’s certainly at the lower end of this scale compared with other breeds!

There are several factors that influence how long chihuahuas will live:

Diet & Nutrition

A healthy diet makes all the difference to a dog’s health and quality of life! In addition to buying the best food you can afford, it is also important to make sure they are getting all of the nutrients from their diet that they require. This is especially true for senior dogs over 7 years of age who have a higher risk of developing dietary deficiencies. Nutritional supplements or special foods may be required in these cases.

Health Considerations

When your chihuahua reaches middle age (7-9 years) there is an increased chance that he will suffer from various health problems, particularly joint problems such as arthritis or hip dysplasia. These conditions cause chronic pain and discomfort which can reduce quality of life so it is essential to look after them appropriately. If not managed properly, it may reduce their life expectancy. However, if managed appropriately these conditions can be managed to allow your Chihuahua to live a full and happy life.

Breed Standards

Because chihuahuas are so small and so light, they often suffer from skeletal problems caused by having too delicate of a frame for their size. They also have very large eyes which can sometimes cause eye problems such as cataracts or glaucoma. Since breed standards tend to favor appearance over health (unfortunately), there is more pressure on breeders and owners to keep them small, even if this reduces the dog’s lifespan and increases the risk of health issues later in life. There is an increased risk of health problems such as heart conditions, liver shunts and metabolic bone disease in larger chihuahuas.

Chihuahua Mixes

Some cross breeds have a significantly different life expectancy to that of purebreds due to their genetic makeup. A chihuahua x pug mix for example is likely to live longer than a pure bred chihuahua because they have a different anatomy and physiology which tends to allow them lead healthier lives with fewer chances of problems later on. In addition, there are some breed mixes that have been specifically designed with the intention of reducing health risks so care should be taken when buying from unknown sources, even if you get a good price!

Lifestyle & Care

The overall quality of your Chihuahua’s life is important for his happiness and your peace of mind! Therefore, consider how active he is, whether or not you can provide him with excellent nutrition, how much housework you are willing to do (grooming), what sort of conditions he will be kept in etc. If you intend on keeping him mostly indoors then don’t choose a long-haired breed (because they get very hot). Instead choose something like the smooth coat Chihuahuas that require less grooming.

The Litter Size

One major factor that differs between breeds is the average litter size of the Chihuahua’s mother. For example, some small breeds such as poodles or shih tzus can have up to 10 puppies in a single litter! Because chihuahuas usually have much smaller litters, the genetic variability is lower and this increases the risk of complications.

Country & Location

the average life span for Chihuahuas may vary from country to country or even region to region due to various environmental factors such as climate, living conditions etc. In some countries, the dogs are kept outside all year round which may increase their risk of health problems whereas other places keep them mostly indoors which can reduce this risk. In addition, geographical location affects lifestyle factors that also contribute towards their overall health and well-being e.g. temperature extremes or humidity levels

Lifestyle Choices

The decisions you make as an owner will affect your Chihuahuas life expectancy. For example, if you choose to keep your dog at a healthy weight, vaccinate him against all illnesses, have regular health check-ups it will help promote his wellbeing and therefore increase the chances of him being around for longer. However, if you decide to let your chihuahua become obese by feeding him treats all year round without exercising him or taking him to the vets for vaccinations – he may have a shorter life expectancy due to various health complications that are associated with obesity.

Affection & Care

A loving owner who cares about their pet’s well-being is likely to spend more time on making choices that promote his good health e.g. providing proper nutrition , grooming every day, vaccinating against disease etc. This means he is less likely to get ill, more likely to take medication when necessary and therefore there is a higher chance that he will live for longer.


A chihuahua’s life expectancy increases with age so it makes sense to look at older dogs in the shelter or who have recently lost their previous pet home. Older Chihuahuas are often already house trained, neutered/spayed, have up-to-date vaccinations etc which reduces the chances of getting any nasty surprises later on! They have also had experiences of living indoors which can be helpful if you are thinking about keeping them inside for most of the time .

Societies & Association

The breed standards of Chihuahuas differ depending on which country or association they are affiliated with. For example, according to the American Kennel Club, the average weight of a healthy chihuahua should be around 6lbs whereas this is closer to 3lbs in other countries. Therefore, if you buy from another type of authority then their standards may not measure up to your expectations. This could result in health problems further down the line so it’s important that you know what sort of life expectancy you can expect when buying from different societies and associations around the world.


According to many breeders, genetics play an important role in determining how long your little dog will live for . For instance, some people recommend that you avoid cross-breeding (e.g chihuahuas breeding with pomeranians) as these dogs tend to have a shorter life expectancy because of their genetics . Whether this is true or not remains debatable but one thing’s for sure – buying from a responsible breeder who knows what they’re doing can help improve the health and quality of your Chihuahua’s offspring making it less likely that he will suffer from any long-term illnesses.


Chihuahuas with pedigree are more likely to lead a longer and healthier life because their parent dogs were screened for genetic conditions e.g hip dysplasia, luxating patella etc which often reduce the chances of developing similar problems as an adult dog. In addition, if you are buying from a breeder who has done all the necessary health tests on their Chihuahuas parents before breeding them – there is less chance that your little friend will inherit these nasty genetic conditions .
