What Issues Are Common To The Chihuahua Breed? Understanding Potential Health Concerns.

Updated: Aug 3, 2023

Chihuahuas are undoubtedly adorable and charming little companions, known for their big personalities and small size. However, like all dog breeds, Chihuahuas are not exempt from certain weaknesses or potential health concerns. In this blog, we will explore some of the common weaknesses found in Chihuahuas and provide insights into how to best care for these beloved pets.

1. Dental Issues:

One of the most prominent weaknesses in Chihuahuas is dental health. Due to their small mouths and overcrowded teeth, these tiny dogs are particularly susceptible to dental problems such as tooth decay, gum disease, and tooth loss. Regular dental care, including daily brushing, dental cleanings, and appropriate chew toys, is vital to maintain their oral health.

2. Hypoglycemia:

Chihuahuas have a high metabolic rate, which makes them more prone to hypoglycemia or low blood sugar. This condition can occur if your Chihuahua skips a meal or experiences excessive physical activity without adequate food intake. Symptoms of hypoglycemia in Chihuahuas include weakness, trembling, disorientation, and even seizures. It's essential to monitor their feeding schedule, provide regular small meals, and keep glucose gel or syrup on hand as a precaution.

3. Patellar Luxation:

Another weakness in the Chihuahua breed is patellar luxation, a condition where the kneecap occasionally slips out of its normal position. This can cause discomfort, lameness, and difficulty in walking. Regular exercise and maintaining a healthy weight can help reduce the risk of this condition. If your Chihuahua shows symptoms, consulting a veterinarian is crucial for proper diagnosis and treatment.

4. Respiratory Problems:

Due to their small size and brachycephalic (short-nosed) skulls, Chihuahuas are prone to respiratory issues. They can develop conditions like collapsed trachea, which causes difficulty breathing and a distinctive honking cough. It's important to avoid exposing them to extreme temperatures, keep them in well-ventilated areas, and prevent undue stress or excitement that may impact their respiratory system.

5. Eye Problems:

Chihuahuas are susceptible to various eye problems, including dry eye, corneal ulcers, cataracts, and progressive retinal atrophy (PRA). Regular eye examinations by a veterinarian can help identify these issues early on and ensure appropriate treatment options are pursued. Keeping the eye area clean, avoiding excessive eye rubbing, and providing a quality diet rich in antioxidants can also promote healthy eyes in Chihuahuas.


While Chihuahuas are a wonderfully unique and endearing breed, it's important for prospective owners to be aware of their potential weaknesses. By understanding these vulnerabilities and taking proactive steps to address them, you can provide the best possible care for your Chihuahua. Regular veterinary check-ups, a nutritious diet, proper dental care, and a safe environment are crucial for keeping your Chihuahua happy and healthy for years to come.
