Chihuahua Health Problems
Check out some common chihuahua health problems here. Chihuahuas are prone to issues that affect small dogs, such as hypoglycemia,
luxating patella, tracheal collapse, and dental problems.
The Chihuahua is the smallest among the AKC registered breeds, weighing around two to six pounds.
Despite their size, chihuahuas are full of life and energy. They are alert and swift-moving and extremely protective of their own family.
The Chihuahua is a long-lived breed, often achieving 16 or more years of age. However, they are susceptible to several health problems that are common to small breed dogs.
If you are thinking of getting a Chihuahua, you need to know about the common health problems that may affect this dog breed.
Of course, not all Chihuahuas will be affected by the common health problems as described below, but keep in mind that they are more predisposed to these illnesses.

Chihuahua Health Problems - Common Small Dog Problems
The Chihuahua is susceptible to several health problems that commonly affect small breed dogs, such as:
[Top of Page]
- Dental Problems: Small breed dogs such as Chihuahuas tend to have tooth and gum diseases - as their mouths are so small,
teeth are overcrowded, making it easy for dental problems to arise. For example, food tends to be
trapped between the teeth, causing plaque and tartar buildup which, overtime if left untreated, can result in periodontal disease such as gingivitis and periodontitis, as well
as premature tooth loss.
Keeping your Chihuahua's teeth clean by daily brushing and regular dental check-ups are essential. Also avoid snacks rich in starch and sugar.
- Hypoglycemia: Hypoglycemia, which is a state of abnormally low blood
sugar, is one of the most common Chihuahua health problems. Hypoglycemia can cause problems to the nervous system, resulting in seizures and even coma.
A hypoglycemic attack may happen without much warning, although sometimes a dog with low blood sugar level may show signs of lethargy, weakness, restlessness, and tremors.
Treating a dog with a hypoglycemic attack takes quick action because even a mild case of
hypoglycemia can deteriorate quickly and can result in permanent brain damage. The best way of course is to
prevent it from happening by taking various precautions.
- Tracheal Collapse: This condition occurs primarily in older small breed dogs, particularly Chihuahuas, Pomeranians, and Toy Poodles. Obese dogs are
especially vulnerable to this health problem.
Tracheal collapse occurs because the tracheal rings do not possess normal rigidity resulting in the collapse of the trachea wall as the dog inhales. The collapse of the
trachea wall leads to a narrowing of the windpipe. Thus, the typical sign of this problem is a goose-honk cough, sometimes accompanied by gagging and harsh breathing, and
made worse by stress and exertion. Coughing may also occur when the dog eats or drinks.
Mild to moderate symptoms can be treated by bronchodilator drugs and a low-stress routine that avoids situations that trigger coughing episodes. In severe cases, surgery may be
necessary. It is advisable to use a harness (not collar) on a chihuahua so that the dog's throat and airway can be protected.
- Chronic Valvular Disease: Small and toy breed dogs (such as Chihuahuas) are predisposed to this common heart disease of unknown cause. Dogs with
this heart disease have degenerative changes in their heart valves. Specifically, the leaflets of the valves grow thick and the shape become distorted. As a result,
the free edges of the valves cannot make contact. This causes lowered valve function and cardiac output.
The hallmark symptom of chronic valvular disease is a loud heart murmur heard over the left side of
the chest. The disease is chronic and progressive, and if left untreated, can develop into
congestive heart failure.

- Luxating Patella: Luxating patella is a congenital disease in
which the alignment of the bones and joints of the hind leg is abnormal, resulting in a displacement of the patella to the side of the joint. The main symptom of luxating
patella is an intermittent hopping on the limb when the patella pops out of place. Depending on the severity of the problem, dogs with luxating patella may need surgical
Other Chihuahua Health Problems
Other Chihuahua health problems that we need to pay attention to include:
- Hydrocephalus: If you have a chihuahua, you will notice that he has a soft spot on the top of his head. It is called a molera which
is not a health problem, just a breed characteristic.
However, Chihuahuas with an exceptionally large molera are prone to a condition called hydrocephalus, which is caused by an excessive accumulation of cerebrospinal
fluid around the brain. Puppies under 9 months old are more prone to this condition, although some dogs may not show symptoms until they get older.
Hydrocephalus causes seizures, partial or complete blindness, dementia, and eventual death, although some dogs with a mild case of hydrocephalus can survive and grow
Treatment involves the use of corticosteroids and diuretics to reduce the production of cerebrospinal fluid. Sometimes surgery is necessary.
- Shivering: This is in fact not a health problem but if you have a Chihuahua, you may notice that your Chi tends to shiver or tremble,
especially under stress or excitement. Toy and small breed dogs have a higher rate of metabolism, causing them to lose body heat faster than other bigger dogs.
Shivering is a way to help generate body heat.
Chihuahuas should always be protected against the cold; therefore be sure that your Chi is well supplied with sweaters and blankets in the cold season.
