Understanding Chihuahua Health Issues

Before we learn the specifics, it’s crucial to grasp the basics of Chihuahua health. These miniature canines, weighing in at just a few pounds, are prone to certain health problems. Being aware of these issues can help you provide the best care for your beloved Chihuahua.

Chihuahua Health Issues: An Overview

Chihuahuas, like all dog breeds, can experience a range of health issues. However, they are particularly susceptible to several conditions, including:

Patellar Luxation in Chihuahuas:

Patellar Luxation is a common Chihuahua health issue that often  takes the spotlight. This condition causes the patella to move out of its usual place. Unfortunately, it makes these small dogs walk in a painful, lurching way.

Patellar Luxation can be mild or severe. Some Chihuahuas just stumble sometimes, while others can’t walk at all.

Fortunately, this condition is treatable if treated promptly. Milder cases may be treated with conservative measures. Rest and anti-inflammatory medication are only some of them. On the other hand, more severe cases may require surgical correction.

With your care and the help of your vet, your Chihuahua can get back to walking normally and live a better, happier life.

Dental Problems in Chihuahuas:

Dental problems in Chihuahuas can be a challenging facet of their overall health. These cute little dogs can have problems with their teeth, so their parents need to keep an eye on them as well. Here is a full look at the types of teeth problems Chihuahuas can have, what causes them, and how they can be treated.

Tooth Decay and Gum Disease:

Just like humans, Chihuahuas can suffer from tooth decay and gum disease due to the buildup of plaque and tartar. Poor dental hygiene, coupled with a high-sugar diet, can exacerbate these issues. Regular tooth brushing, dental chews, and professional cleanings are vital to combat tooth decay and gum disease.


Chihuahuas’ tiny mouths often result in overcrowded teeth. This can lead to misalignment and difficulty in maintaining proper oral hygiene. In severe cases, it might require dental extractions to alleviate discomfort and prevent further issues.

Tooth Fractures:

These can occur due to chewing on hard objects or accidental trauma. Fractured teeth can be painful and may need to be extracted or treated with dental bonding to restore function.

Plaque and Tartar Buildup:

Chihuahuas are prone to rapid plaque and tartar buildup, which can lead to bad breath, gum disease, and tooth decay. Regular brushing and professional cleaning can help prevent this. We also recommend you to allow your pet to play with chew toys made of rubber. Chihuahua toys can help in decreasing tartar and plaque, and also serve as mental stimulation for your pet.

Periodontal Disease:

If gum disease isn’t taken care of, it can lead to periodontal disease, which affects the parts of the teeth that hold them in place. It can result in tooth loss and systemic health issues. Treatment may involve dental cleanings, antibiotics, and sometimes, tooth extraction.

Oral Masses and Tumors:

Chihuahuas can develop oral masses or tumors, which may require surgical removal and biopsy to determine their nature.

Preventive measures play a pivotal role in maintaining your Chihuahua’s oral health. Daily tooth brushing using canine toothpaste and a soft-bristle brush is highly recommended. Dental chews and toys designed to promote oral hygiene can aid in plaque removal. Additionally, providing a balanced diet and limiting sugary treats can help prevent tooth decay.

Regular dental check-ups with a veterinarian are crucial. Professional cleanings may be required annually or as recommended by your vet. During these cleanings, your Chihuahua will be under anesthesia to ensure a thorough examination and cleaning without causing them stress or discomfort.

Hypoglycemia in Chihuahuas:

Hypoglicemia is one of the most common Chihuahua health issues. .This condition is followed by low blood sugar, and can be especially worrying for these pooches. To make sure your Chihuahua is healthy, you must know why it happens and how to deal with it.

Causes of Hypoglycemia in Chihuahuas:

  • Fast Metabolism: Chihuahuas boast a rapid metabolism, and this, coupled with their petite size, means they burn through energy quickly. Skipping meals or extended periods between meals can lead to low blood sugar levels.
  • Stress and Anxiety: Chihuahuas are known for their sensitive nature, and stress or anxiety can trigger a drop in blood sugar. Events such as travel, change in environment, or separation from their owners can induce stress-related hypoglycemia.
  • Intense Activity: Overexertion during play or exercise without sufficient food intake can deplete their energy reserves, resulting in low blood sugar.
  • Cold Weather: Chihuahuas are sensitive to cold temperatures. It can lead to shivering and increased energy expenditure, potentially causing hypoglycemia if they don’t consume enough calories to compensate.

Healing Hypoglycemia in Chihuahuas:

  • Frequent Meals: To prevent hypoglycemia, Chihuahuas should be fed multiple small meals throughout the day, ensuring a steady supply of energy.
  • Balanced Diet: Providing a well-balanced diet tailored to their specific needs can help stabilize blood sugar levels. Consult your veterinarian for dietary recommendations.
  • Stress Reduction: Minimize stressful situations for your Chihuahua whenever possible. Familiar environments and routines can help alleviate anxiety-related hypoglycemia.
  • Regular Exercise: While exercise is essential, it should be balanced with adequate calorie intake. Ensure your Chihuahua doesn’t overexert themselves during playtime or walks.
  • Monitor Blood Sugar: If your Chihuahua is prone to hypoglycemia, talk to your vet about how often you should check their blood sugar levels.
  • Emergency Measures: If your Chihuahua has severe hypoglycemia and is weak, shivering, or having seizures, you need to react quickly.

Low blood sugar can be a concern, especially in Chihuahua puppies. It can lead to weakness and seizures.

Tracheal Collapse in Chihuahuas:

Chihuahuas have fragile tracheas, which can collapse due to stress or strain. This leads to a distinctive coughing sound often described as a “goose honk.” To minimize the risk, use a harness instead of a collar when walking your Chihuahua, as collars can put pressure on the throat.

Chihuahua health issues: How to treat trachea collapse?

1. Weight Management:

Maintaining a healthy weight is paramount. Extra pounds can place unnecessary stress on the trachea, exacerbating the condition. Consult your veterinarian for a proper diet plan tailored to your Chihuahua’s needs.

2. Use a Harness:

Opt for a harness instead of a collar when walking your Chihuahua. Collars can put pressure on the throat, but a harness spreads the force out evenly, making it less likely that the trachea will get sore or break.

3. Medication:

In mild cases, your vet may give your Chihuahua cough suppressants or bronchodilators. They’ll ease the symptoms and make his/her life better.

4. Lifestyle Adjustments:

Make modifications to your Chihuahua’s lifestyle. Minimize exposure to irritants such as smoke or harsh chemicals, as these can exacerbate tracheal issues.

5. Humidification:

Using a humidifier in your Chihuahua’s environment can help soothe their airways. They can reduce coughing episodes, especially in dry climates.

6. Surgical Intervention:

In severe cases where conservative measures are ineffective, surgical options may be considered. Procedures like tracheal stenting or the placement of prosthetic rings can provide structural support to the trachea, improving airflow.

7. Veterinary Consultation:

Regular check-ups with your veterinarian are crucial. They can monitor your Chihuahua’s condition, adjust treatment plans as needed, and provide guidance on managing tracheal collapse effectively.

Remember that the best way to treat your Chihuahua will depend on how bad the collapsed trachea is and what your dog needs.

It’s important to work closely with your vet to come up with a treatment plan that will make your Chihuahua comfortable.

Heart Problems in Chihuahuas:

Even though they are small, these cute pets can suffer from a number of heart problems. It’s important for your Chihuahua’s health that you know about these problems, how they show up, and what you can do to fix them.

Common Heart Problems in Chihuahuas:

  • Heart Murmurs: Heart murmurs are abnormal sounds in the heart, often indicating turbulent blood flow. They can be a sign of an underlying heart condition and are typically graded on a scale of severity.
  • Congestive Heart Failure (CHF): CHF occurs when the heart can’t pump blood effectively, leading to fluid accumulation in the lungs and body. Chihuahuas may develop CHF due to their predisposition to heart disease.
