Common Health Issues in Mastiffs (English & Neapolitan) and How to Spot Them Early
Table of Contents
ToggleMastiffs, both English and Neapolitan, are iconic for their immense size, powerful build, and loyal temperament. While these gentle giants make excellent guardians and devoted family members, their sheer size predisposes them to several health issues that can affect their quality of life.
Understanding the common health concerns in Mastiffs and recognizing the early warning signs is essential for any owner who wants to provide the best care possible. In this article, we’ll explore the most prevalent health issues in English and Neapolitan Mastiffs and how to spot them early to ensure a healthier, happier life for your beloved companion.
1. Hip Dysplasia: A Common Joint Issue in Large Breeds
What Is It?
Hip dysplasia is a genetic condition in which the hip joint doesn’t fit properly into the hip socket. Over time, this misalignment causes inflammation, pain, and arthritis, leading to mobility problems. Both English and Neapolitan Mastiffs are highly susceptible due to their size and rapid growth rates.
Why Mastiffs Are Prone:
Their heavy frame and fast growth put extra stress on developing joints, increasing the risk of hip dysplasia.
Early Signs to Watch For:
Reluctance to rise, jump, or run
Limping, particularly in the hind legs
Swaying or “bunny-hopping” gait
Difficulty climbing stairs
Muscle atrophy in the hindquarters
Discomfort when the hip area is touched
Preventive Measures:
Keep your Mastiff at a healthy weight to reduce joint strain
Provide joint supplements like glucosamine and chondroitin
Schedule regular X-rays to monitor joint development
Opt for low-impact exercises like swimming or controlled walks
Consult a vet about surgical options in severe cases
2. Gastric Dilatation-Volvulus (Bloat): A Life-Threatening Emergency
What Is It?
Bloat, or Gastric Dilatation-Volvulus (GDV), is a critical condition in which the stomach fills with gas and twists, cutting off blood flow. This can rapidly lead to shock and death if not treated immediately. Mastiffs, with their deep, broad chests, are at high risk for GDV.
Why Mastiffs Are Prone:
Their deep chests create more room for the stomach to twist and trap gas, increasing the risk of bloat.
Early Signs to Watch For:
Swollen, hard abdomen
Unproductive retching or gagging
Restlessness and pacing
Excessive drooling and panting
Rapid, shallow breathing
Collapse or signs of shock (pale gums, weak pulse)
Preventive Measures:
Feed multiple small meals instead of one large meal
Use a slow-feed bowl to prevent gulping
Avoid exercise immediately after meals
Consider gastropexy surgery (stomach tacking) as a preventive measure
Be aware of the signs and keep emergency contacts handy
3. Heart Disease: A Serious Concern in Mastiffs
What Is It?
Dilated Cardiomyopathy (DCM) is a condition in which the heart muscle becomes weak and enlarged, compromising its ability to pump blood effectively. This can lead to heart failure, and it is a prevalent concern in large breeds like Mastiffs.
Why Mastiffs Are Prone:
Their large size puts immense pressure on the heart, making them more vulnerable to heart disease.
Early Signs to Watch For:
Persistent coughing, especially at night
Lethargy and decreased stamina
Fainting or sudden collapse
Rapid breathing or difficulty breathing
Swollen abdomen due to fluid buildup
Pale or bluish gums
Preventive Measures:
Schedule annual cardiac screenings, including echocardiograms
Feed a heart-healthy diet rich in taurine and omega-3 fatty acids
Maintain a healthy weight to reduce cardiac stress
Monitor for signs of lethargy, coughing, or breathing difficulties
Administer heart medications as prescribed by the vet
4. Cherry Eye: A Common Eye Condition
What Is It?
Cherry eye occurs when the gland of the third eyelid prolapses, creating a red, swollen mass in the corner of the eye. This condition is more common in Neapolitan Mastiffs due to their loose skin and prominent facial folds.
Why Neapolitan Mastiffs Are Prone:
Their heavy, droopy facial structure makes them more susceptible to gland prolapse.
Early Signs to Watch For:
Red or pink swelling in the corner of the eye
Watery discharge or excessive tearing
Pawing at the eye due to discomfort
Squinting or blinking more than usual
Preventive Measures:
Keep the eyes clean and monitor for redness or swelling
Consult a vet immediately for persistent eye irritation
Surgical correction may be necessary to prevent chronic issues
5. Osteosarcoma: Bone Cancer in Giant Breeds
What Is It?
Osteosarcoma is an aggressive form of bone cancer that primarily affects the long bones. It is more common in older, large-breed dogs, including Mastiffs.
Why Mastiffs Are Prone:
Their massive bone structure puts them at greater risk for developing bone cancer, especially as they age.
Early Signs to Watch For:
Persistent limping or lameness
Swelling or a noticeable lump on a leg
Pain when the affected area is touched
Sudden fractures with minimal trauma
Unexplained weight loss and lethargy
Preventive Measures:
Regular body checks for lumps or swelling
Immediate X-rays for unexplained lameness or pain
Early diagnosis is critical for treatment options like amputation or chemotherapy
6. Skin Infections and Fold Dermatitis
What Is It?
Both English and Neapolitan Mastiffs have loose skin folds that can trap moisture and bacteria, leading to skin infections, hot spots, and dermatitis.
Why Mastiffs Are Prone:
Their heavy, wrinkled skin provides a breeding ground for bacteria, especially in humid or warm conditions.
Early Signs to Watch For:
Red, inflamed skin folds
Foul odor from the folds
Excessive scratching or licking
Oozing or crusting skin
Hair loss in affected areas
Preventive Measures:
Clean skin folds regularly with gentle, dog-safe wipes
Keep skin folds dry to prevent bacterial growth
Apply medicated ointments as prescribed
Monitor for signs of infection and consult the vet if symptoms persist
Conclusion: Staying Ahead of Potential Health Issues in Mastiffs
Mastiffs are regal, imposing, and endlessly loyal. However, their size and genetics make them prone to several serious health conditions, including hip dysplasia, heart disease, bloat, and osteosarcoma. Early detection, regular veterinary checkups, and preventive care can make a significant difference in their quality of life.
Whether you own a stately English Mastiff or a powerful Neapolitan Mastiff, being vigilant about their health and recognizing the early signs of these conditions can help you act quickly and provide the best possible care.
