How long a dog lives depends mainly on its size: the smaller the dog breed, the longer it lives. The small body size allows Chihuahuas to live for as long as 18 to 20 years

What is the average lifespan of a Chihuahua?

Although there is no fixed rule for how long a Chihuahua lives, the agreed-upon average lifespan of a Chihuahua is 14 to 16 years. We’ll discuss Chihuahua’s lifespan in a bit more detail below.

Chihuahua lifespan

When it comes to Chihuahuas, the most you can ask is for them to make it till 20 years, plus a few months. There aren’t many credible claims of a Chihuahua surpassing that age.

A healthy, happy, and active Chihuahua would naturally live longer. But Chihuahua owners and breeders should also know about several common health issues that can shorten their little dog’s lifespan.

Common Chihuahua health problems

Chihuahuas are inherently susceptible to certain health issues. While not all of these are deadly, they can shorten your Chihuahua’s lifespan if left untreated. These health problems include:

Chihuahua dental issues

Although Chihuahuas are small, they are fierce and will bite strangers if they feel unsafe. Chihuahuas are not afraid to show their sharp little teeth in order to scare strangers away. You may agree with me when I say that our Chihuahuas think that they are Pit bulls or lions! Their teeth are their defense mechanism.

This is why it’s important that dog owners help their Chihuahuas maintain healthy teeth. Chihuahuas have tiny mouths with sensitive teeth and unfortunately, they are more prone to dental infections than bigger dogs.

If the dental infections worsen, the bacteria can spread to the Chihuahuas’ internal organs, damaging their liver, heart, and kidneys.

Since a proper diet is critical at later stages of life, you can see how dental issues can shorten your Chihuahua’s lifespan. However, brushing regularly and avoiding sweets can help keep these issues at bay.

Canine obesity in Chihuahuas

Chihuahuas don’t require too many calories to sustain their petite bodies, and feeding them in excess can make them fat. 

Obesity is the mother of diseases in canines and can give rise to a myriad of life-shortening health complications. Obese Chihuahuas often suffer from joint, heart, kidney, and liver problems during the later stages of their lives.

To keep your little Chihuahua safe from these health issues, feed them sensibly and allow them plenty of exercise.

Osteoarthritis

Osteoarthritis is when the protective coating between the dog’s joints deteriorates. As a result, the bones that are exposed rub against each other. This causes severe discomfort and pain, which makes it difficult for our Chihuahua to do any physical activities.

Arthritis also reduces a dog’s movement and can make him or her feel miserable. The combination of discomfort and depression can reduce a Chihuahua’s lifespan by a good few years.

Hypoglycemia in Chihuahua

Toy breeds such as Chihuahuas are more vulnerable to hypoglycemia — a condition in which the body is unable to retain sufficient blood sugar. This disease is a silent killer, and symptoms usually show when it has gotten out of control.

Giving your Chihuahuas a high-quality diet can keep their blood sugar at a healthy level throughout the day. Make sure that the diet is enough to keep them nourished, but not so much that it leads to obesity.

Patellar Luxation Chihuahua

Some Chihuahuas have a hereditary condition that causes their kneecaps to dislocate randomly. If this happens, your Chihuahuas will cry or whimper because they will be in pain the first time it happens.

If you notice them crying or whimpering in pain, be sure to contact your vet right away. This is a serious health concern and if it’s not treated in time, your pooch will try to get used to it after a while and this condition could get worse.

The Chihuahua patella luxation treatment requires surgery, but that route is only taken in extreme cases. Normally, physiotherapy is enough to keep the dog’s knees in place by strengthening the leg muscles. Alternatively, your Chihuahua could also wear a dog brace.

Hydrocephalus Chihuahua

This condition affects Chihuahuas under the age of 6 months and is usually fatal. It happens when the naturally occurring opening in their skull, called Molera, is abnormally large. This can lead to a fluid build-up in the pup’s head, resulting in seizures, swelling, and death.

Although uncommon, this disease usually occurs during the early months of a Chihuahua’s life. If you’re looking to adopt a Chihuahua puppy, get him or her thoroughly checked for hydrocephalus.

Chihuahua heart problems

Chihuahuas have very tiny hearts and are prone to several cardiac problems. The Chihuahua heart problem can be inherited or develop later on in life. 

Valve disease is a hereditary heart problem in Chihuahuas. In this condition, the heart’s valves thicken and deform, hampering its function and consequently shortening the Chihuahua’s life.

Chihuahua collapsed trachea

This condition occurs when the dog’s windpipe collapses, making it difficult to breathe. Chihuahuas with a collapsed trachea may develop a chronic cough and make honking sounds when they inhale or exhale. 

Collapsed trachea is common among Chihuahuas and can be treated with medications. Severe cases in which the dog can’t breathe require surgery.

9 Factors that impact the Chihuahua lifespan

1. Nutrition

Chihuahuas are tiny dogs and hence require sensible feeding. An excessively rich diet with regular sugary snacks can easily make them fat, whereas insufficient nutrition can cause them to develop deficiencies. 

2. Physical fitness

Obesity leads to a host of diseases. Besides sensible feeding habits, a Chihuahua needs to stay active and get their recommended daily exercise in order to have a long and healthy life.

3. Breed

Cross and selective breeding with the right dog species can alter a Chihuahua’s lifespan. Toy breeds are the most delicate, while Chihuahua-terrier mixes live the longest.

4. Gender

On average, female Chihuahuas live a couple of years longer than male Chihuahuas. Scientists have varying opinions on why that is so, but the exact cause is unknown.

5. Emotional health

Chihuahuas who live happily will live longer. Love and care greatly impact a Chihuahua’s lifespan, and depressed or neglected Chihuahuas perish much earlier.

6. Vaccination

Unvaccinated Chihuahuas are at the mercy of their natural immune system, which isn’t usually strong enough to ward off some nasty viruses. As the Chihuahua dogs ages, their immune response also weakens, making them an easy target for viruses.

7. Dental health

The long years take their toll on a Chihuahua’s teeth. As the Chihuahua loses its teeth, his or her diet is also affected. Tooth pain is also very irritating, and the stress may shorten the Chihuahua’s lifespan.

8. Sexual health

Spayed or neutered Chihuahuas live longer than their fertile counterparts. Keep in mind that each Chihuahua pregnancy and birth can take years off a female Chihuahua’s life, whereas males that aren’t neutered are more violent, reckless, and likely to wander off. 

9. Cardiac health

Chihuahuas have naturally sensitive hearts, and dogs with heart issues have a tough old age. That’s why ensuring optimum cardiac health is crucial for a Chihuahua’s long life. 

7 Ways to Help Your Chihuahua Live a Long, Happy, and Healthy Lives

1. Dental hygiene

Regular brushing, avoiding sweets, and bi-monthly dental visits can ensure the Chihuahuas keeps their pearly whites healthy and holds onto them well into old age.

2. Regular exercise

Physical fitness is critical in maintaining a healthy body for your little pooch. As long as your Chihuahua is young, keep them physically active. It will strengthen their bodies and bones for the hardships of old age.

3. Vaccination

Vaccination will give your Chihuahua immunity from diseases that may cause an untimely demise. Any virus will have a hard time troubling your dog if he or she is vaccinated.

4. Regular checkups

Regular visits to the vet give you the inside scoop of how healthy your Chihuahua is. The vet may be able to catch diseases before they spread throughout the body. Routine checkups also allow the vet to check whether your canine friend has any deficiencies.

5. Sensible diet

A clean, low-calorie diet is the key to a long healthy life. Feed your Chihuahua in moderation, and keep them away from sweets, snacks, and other human foods.

6. Spaying and neutering

Spaying prevents female Chihuahuas from bearing the burden of an unplanned or unexpected pregnancy, whereas neutering makes male Chihuahuas calmer, less likely to engage in fights, or run away from home.

7. Safety precautions

Despite their frail bodies, Chihuahuas can be very temperamental and often get into situations where they can get hurt. Keeping your Chihuahuas on a leash and away from trouble will ensure they don’t foolishly risk their lives.
