Maltese are generally healthy dogs with an average lifespan of 12-15 years, though many live well into their late teens with proper care. The breed benefits from its ancient lineage and relatively stable breeding practices, though like all purebred dogs, Maltese are susceptible to certain hereditary health conditions. Responsible breeders perform health testing on breeding dogs to minimize the incidence of genetic diseases, and owners should partner with veterinarians to maintain their Maltese's health throughout life.
Luxating patella is one of the most common orthopedic problems in Maltese and other toy breeds. This condition occurs when the kneecap slips out of its normal position, causing lameness, pain, and difficulty walking. Severity ranges from grade 1 (mild, occasional slipping) to grade 4 (severe, with the patella permanently displaced). Mild cases may require only weight management and restricted jumping, while severe cases may need surgical correction. Reputable breeders have breeding stock evaluated for patellar stability by veterinarians. Maintaining ideal body weight reduces stress on joints and may prevent progression of mild cases.
Progressive Retinal Atrophy (PRA) is a hereditary eye disease that can affect Maltese, causing gradual vision loss leading to blindness. Several forms of PRA exist, with symptoms typically appearing in middle age or later. Genetic testing is available for some forms, allowing breeders to make informed breeding decisions. While there is no treatment for PRA, affected dogs can adapt well to vision loss with patient owner support and environmental modifications. Annual eye examinations by veterinary ophthalmologists can detect early changes and monitor progression.
Portosystemic liver shunt is a congenital condition that occurs in some toy breeds including Maltese. This vascular abnormality causes blood to bypass the liver, preventing proper toxin filtering and causing various symptoms including poor growth, lethargy, seizures, and gastrointestinal issues. Diagnosis requires blood tests and imaging studies. Treatment may involve dietary management, medication, or surgical correction depending on the type and severity of the shunt. Early diagnosis and appropriate treatment allow many affected dogs to live normal lives.
Heart problems including patent ductus arteriosus (PDA) and mitral valve disease can affect Maltese. PDA is a congenital condition where a fetal blood vessel fails to close properly after birth, requiring surgical correction. Mitral valve disease is more common in older dogs, causing heart murmurs and potentially leading to congestive heart failure. Regular veterinary examinations including heart auscultation help detect heart problems early. Treatment may include medications to manage heart function and reduce symptoms.
Dental disease is particularly problematic in Maltese and other toy breeds due to their small mouths and crowded teeth. Without regular dental care, Maltese can develop severe periodontal disease leading to tooth loss, pain, and systemic infections affecting the heart, liver, and kidneys. Daily tooth brushing with dog-specific toothpaste, regular professional dental cleanings under anesthesia, and dental-friendly treats and toys help maintain oral health. Untreated dental disease significantly impacts quality of life and can shorten lifespan.
Hypoglycemia, or low blood sugar, can affect Maltese puppies and occasionally adults, particularly those under four pounds. Small toy breeds have high metabolic rates and limited glycogen stores, making them vulnerable to blood sugar drops. Symptoms include weakness, trembling, disorientation, and potentially seizures. Feeding multiple small meals daily and ensuring the dog eats regularly prevents hypoglycemic episodes. Immediate treatment with honey or corn syrup on the gums followed by feeding can reverse acute episodes. Chronic hypoglycemia requires veterinary evaluation to rule out underlying causes.
Regular veterinary care is essential for maintaining Maltese health throughout life. Annual wellness examinations allow early detection of developing problems before they become serious. Puppies require a series of vaccinations to protect against infectious diseases, with booster vaccinations continued throughout life according to protocols based on risk assessment and lifestyle. Parasite prevention including heartworm, flea, and tick control should be maintained year-round according to veterinary recommendations.
Weight management is important for Maltese health and longevity. Obesity exacerbates joint problems, contributes to heart disease, and reduces lifespan. Maltese should have a visible waist and ribs that can be felt easily under a thin layer of fat. High-quality diet appropriate for toy breeds, portion control, and regular exercise maintain ideal weight. Avoiding excessive treats and table scraps prevents weight gain. Working with your veterinarian to establish appropriate feeding guidelines ensures your Maltese maintains healthy body condition throughout life.
Spaying or neutering provides health benefits and prevents unwanted litters. Female Maltese benefit from reduced risk of mammary cancer and eliminate the risk of pyometra (uterine infection). Male Maltese benefit from reduced risk of testicular cancer and certain prostate problems. Timing of spay/neuter surgery should be discussed with your veterinarian, as recent research suggests waiting until growth is complete may provide orthopedic benefits. Regular dental care, appropriate preventive medicine, proper nutrition, and attentive monitoring for health changes help ensure Maltese live long, healthy, comfortable lives as beloved family companions.
