7 Common Health Issues in Chihuahuas – Prevention and Care Tips for Owners
Why Chihuahuas Need Extra Health Attention
The Chihuahua is the world’s smallest dog breed, known for its alertness, bold personality, and strong bond with its owner.
But due to its tiny build and genetic vulnerabilities, it’s also prone to a variety of health concerns.
Here are the most common health issues in Chihuahuas and how to prevent or manage them effectively for a longer, healthier life.
⚠️ 7 Common Health Issues in Chihuahuas
1. Patellar Luxation
This is one of the most common health issues in Chihuahuas.
The kneecap slips out of position, causing discomfort and limping.
-
Symptoms: skipping, hind leg lifting, knee clicking
-
Prevention: avoid jumping, use non-slip mats, maintain ideal weight
-
Treatment: physical therapy or surgery for severe cases
2. Tracheal Collapse
A classic Chihuahua condition that causes a honking cough or noisy breathing due to a weakened trachea.
-
Prevention: always use a chest harness instead of a neck collar
-
Management: bronchodilators, cough suppressants, reduced stress
3. Hypoglycemia (Low Blood Sugar)
This is a life-threatening issue in young or tiny Chihuahuas, especially puppies.
-
Symptoms: weakness, shaking, seizures, disorientation
-
Prevention: feed small meals 3–4 times a day
-
Emergency care: rub honey or syrup on gums and visit a vet immediately
4. Heart Disease (Mitral Valve Disease)
Aging Chihuahuas are prone to this chronic heart condition,
which can progress silently without early detection.
-
Symptoms: chronic cough, shortness of breath, reduced activity
-
Prevention: annual cardiac exams and low-sodium diets
-
Treatment: long-term medication and monitoring
5. Dental Disease
Due to their small jaws, Chihuahuas are highly prone to plaque buildup, gum disease, and bad breath.
-
Prevention: daily brushing, dental chews or sprays
-
Management: regular dental cleanings and extractions if needed
6. Hydrocephalus
This congenital neurological disorder involves an accumulation of cerebrospinal fluid in the brain, more common in Chihuahuas due to their dome-shaped skulls.
-
Symptoms: head pressing, seizures, unsteady walking
-
Diagnosis: MRI or CT scan
-
Treatment: lifelong medical therapy or surgery in severe cases
7. Allergic Dermatitis
A common health issue in Chihuahuas due to their sensitive skin.
They may react to food, dust, pollen, or flea bites.

Treatment: antihistamines, corticosteroids, vet evaluation
