Chihuahua Dog Health Concerns – Guide to Causes, Symptoms and Treatments
Summary
Chihuahuas, the smallest dog breed in the world, are cherished for their big personalities and loyal companionship. However, despite their diminutive size, these dogs can face a variety of health challenges throughout their lives. This article provides a detailed analysis of common health issues in Chihuahuas, their symptoms, physiological causes, and treatment protocols. It also outlines nutritional strategies, including the role of specific foods, nutrients, medicinal herbs, adaptogens, prebiotics, probiotics, postbiotics, and other bioactive compounds, in preventing or mitigating these health problems. Frequently asked questions provide further insights to help Chihuahua owners ensure their pets lead long, healthy lives.
Chihuahuas are a toy breed originating from Mexico, where they have a long history dating back to ancient civilisations. They are known for their compact size, alert expressions, and confident temperaments. As affectionate and intelligent companions, they thrive in households of all sizes.
Unique Physical Characteristics
Chihuahuas have large, expressive eyes, erect ears, and a compact, lightweight frame. While these traits contribute to their charm, they also make them more susceptible to certain health challenges, such as eye conditions and joint problems.
Common Health Problems in Chihuahuas
According to research undertaken by the Royal Veterinary College (RVC) VetCompass™ program, the most common health concerns of Chihuahuas were dental disease (13.5%), obesity (5.9%) and retained baby teeth (5.7%). Compared with other dogs, Chihuahuas were more prone to aggression (4.2%), slipping kneecap (4.0%) and retained testicles (3.9%).
This common orthopedic condition occurs when the kneecap dislocates from its normal position, causing intermittent lameness, skipping, or pain. It is often genetic and can worsen over time without proper management.
Chihuahuas’ small jaws and crowded teeth make them prone to periodontal disease, tartar buildup, and tooth loss. Dental problems can lead to infections and systemic health issues if untreated.
Low blood sugar is a frequent concern in young or small Chihuahuas, particularly during periods of stress, fasting, or illness. Symptoms include lethargy, weakness, tremors, and seizures.
Chihuahuas are predisposed to heart problems, including mitral valve disease (MVD), also known as mitral valve insufficiency (MVI) and patent ductus arteriosus (PDA). These conditions can lead to heart murmurs, coughing, and reduced exercise tolerance.
A weakened or flattened trachea can cause difficulty breathing, coughing, and wheezing, particularly in overweight Chihuahuas or those exposed to environmental irritants.
This condition, characterised by an accumulation of cerebrospinal fluid in the brain, is more common in toy breeds. Symptoms include an enlarged skull, behavioural changes, and seizures.
Idiopathic epilepsy is common in Chihuahuas and is characterised by recurring seizures with no identifiable cause. Management often involves medication and lifestyle adjustments.
Obesity
While small in size, Chihuahuas are prone to obesity, which exacerbates joint issues, heart problems, and diabetes.
Allergies (Food and Environmental)
Allergies can manifest as itchy skin, ear infections, or gastrointestinal upset. Common triggers include certain proteins, pollen, and household dust mites.
Physiological Causes of Health Issues
Genetic Predispositions
Selective breeding has contributed to the prevalence of conditions like luxating patella, dental disease, and PRA in Chihuahuas.
Structural and Physiological Traits
Chihuahuas’ small size and anatomical features, such as their prominent eyes and compact jaws, predispose them to specific health challenges.
Environmental and Lifestyle Factors
Factors such as diet, exercise, exposure to allergens, and stress levels significantly impact the health and wellbeing of Chihuahuas.
Symptoms and Treatment Protocols
Recognising Health Issues in Chihuahuas
Common symptoms to watch for include limping, dental tartar buildup, lethargy, coughing, seizures, excessive scratching, and changes in weight or appetite. Prompt veterinary attention is essential for diagnosis and management.
Medical and Surgical Interventions
Luxating Patella: Anti-inflammatory medications, weight management, and surgical correction in severe cases.
Dental Disease: Regular cleanings, tooth extractions, and antibacterial rinses.
Hypoglycaemia: Immediate administration of glucose (e.g., honey or syrup) and long-term dietary adjustments.
Heart Conditions: Medications to manage symptoms; PDA may require surgical correction.
Collapsed Trachea: Weight management, harness use instead of collars, and bronchodilators.
Eye Conditions: Lubricating drops, pressure-reducing medications, or surgical intervention.
Epilepsy: Anti-seizure medications and a stable routine to minimise stress.
Obesity: Calorie-controlled diets and increased activity levels.
Bilberry: Enhances ocular blood flow and reduces inflammation.
Vitamin A: Essential for maintaining healthy vision.
Frequently Asked Questions
Do Chihuahuas have a lot of health problems?
Chihuahuas are generally healthy but are prone to specific issues due to their size and genetics. Proper care and regular veterinary check-ups can mitigate many risks.
The average Chihuahua lifespan was 8.2 years but can live from 12-14 years with proper care. (1)
What is the life expectancy of a female Chihuahua?
Female Chihuahuas live 10.2 years on average but can 12–14 years, depending on their health and care. (1)
What is the life expectancy of a male Chihuahua?
Male Chihuahuas have a shorter average lifespan of 6.9 years but as with females can live 8-10 years with good care. (1)
What percentage of Chihuahuas have health problems?
Studies indicate that approximately 50–60% of Chihuahuas experience at least one significant health issue in their lifetime.
What are the common causes of death for Chihuahuas?
The most common causes of Chihuahua deaths were heart disease (18.8%), lower respiratory tract disorder 16.3% and traumatic injury (13.8%). (2)
Are there health concerns related to Chihuahua coat colours?
Coat colour does not generally affect health, but rare colours may be linked to unethical breeding practices, which could increase genetic health risks.
Conclusion
Chihuahuas are delightful companions, but their small size and genetic predispositions require attentive care to prevent and manage common health issues. By recognising potential problems early, providing a tailored diet with targeted nutrients, and ensuring regular veterinary check-ups, owners can help their Chihuahuas enjoy long, healthy lives. Responsible breeding practices also play a crucial role in reducing hereditary health problems in this beloved breed.

About Glendon Lloyd Dip.Canine.Nutrition Dip.Dog.Nutrigenomics
I have had dogs from the day I was born. Much to my Mum's amusement, my Dad bought home Zetta, a beautiful corgi pupp , as his contribution to our new family!
Fast forward to 2018 and Catherine, my wife, and one of our dogs Poppy, were both diagnosed and treated for cancer within months of each other
Diet and its impact on health, cancer particularly, led me down a rabbit hole of discovery.
I consumed information voraciously - on our diets, our dogs' diets and the impact these have not just on health but also the health of our increasingly fragile planet.
I was humbled by the time and expertise given so freely by doctors and vets, canine nutritionists and scientists, academics and agronomists. The more I learned the more I understood there had to be a better way to improve not just our health but also our dogs and the planet's.
The result of my trip down that rabbit hole is Bonza, a plant-based dog food (and now supplements) that elevate our dogs' diet beyond simple nutrition to a diet that inspires a healthier everyday life for our dogs and the planet.
I am continually researching the nutritional impact our dogs' diets have on their health and wellbeing and the ingredients and nutrients we should include in, and exclude from, their food to deliver longer, healthier lives.
I am delighted that my trip down the rabbit hole has led to me completing a Diploma in Canine Nutrigenomics and a Diploma in Canine Nutrition being awarded a Distinction for both my coursework and theses!
