Maltese are generally healthy, but like all breeds, they’re prone to certain health conditions. Not all Maltese will get any or all of these diseases, but it’s important to be aware of them if you’re considering this breed. If you’re buying a puppy, find a good breeder who will show you health clearances for both your puppy’s parents. Health clearances prove that a dog has been tested for and cleared of a particular condition.

In Maltese, you should expect to see health clearances from the Orthopedic Foundation for Animals (OFA) for hip dysplasia (with a score of fair or better), elbow dysplasia, hypothyroidism, and von Willebrand’s disease; from Auburn University for thrombopathia; and from the Canine Eye Registry Foundation (CERF) certifying that eyes are normal. You can confirm health clearances by checking the OFA web site (offa.org).

• Patellar luxation: The patella is the kneecap. Luxation means dislocation of an anatomical part (as a bone at a joint). Patellar luxation is when the knee joint (often of a hind leg) slides in and out of place, causing pain. This can be crippling, but many dogs lead relatively normal lives with this condition.
• Portosystemic liver shunt: This renal disorder occurs when an abnormal vessel causes blood to bypass the liver and therefore not be cleansed.
• Progressive Retinal Atrophy (PRA): A degenerative eye disorder. Blindness caused by PRA is a slow process resulting from the loss of photoreceptors at the back of the eye. PRA is detectable years before the dog shows any signs of blindness. A reputable breeder will have dogs’ eyes certified annually by a veterinary ophthalmologist.
• Hypoglycemia: This malady is caused by low blood sugar. Some of the signs may include weakness, confusion, a wobbly gait, and seizure-like episodes. If your dog is susceptible to this, talk to your vet about prevention and treatment options.
• White Dog Shaker Syndrome: This disorder that primarily affects white dogs. Signs of the condition are tremors over the entire body, lack of coordination, and rapid eye movements. Episodes usually start when the dog is six months to three years old and is stressed or overly excited. This condition isn’t painful and doesn’t affect the dog’s personality. If you suspect your Maltese has White Dog Shaker Syndrome, talk to your vet about treatment options.
• Collapsed trachea: Some dogs are prone to this condition, in which the trachea, which carries air to the lungs, tends to collapse easily. The most common sign of a collapsed trachea is a chronic, dry, harsh cough that many describe as being similar to a “goose honk.” Collapsed trachea can be treated medically or surgically.
• Reverse sneezing: Sometimes confused with a collapsed trachea, this is a far less serious condition and lasts only a few minutes. Reverse sneezing primarily occurs when your dog is excited or tries to eat or drink too fast. It also can occur when there are pollens or other irritants in the air. Secretions from the dog’s nose drop onto their soft palate, causing it to close over the windpipe in an automatic reaction. This can be very frightening to your Maltese, but as soon as he calms down, the reverse sneezing stops. Gently stroke his throat to help him relax.
• Syringomyelia (SM): A severe, chronic condition that affects the spinal cord. When fluid-filled cavities or cysts — known as syrinxes — form within the central canal of the spinal cord, they can expand and cause damage to the spinal cord’s tissue. This process can lead to a variety of symptoms, ranging from mild discomfort to severe pain and partial paralysis. The condition is most commonly seen in certain toy breeds but can affect any dog.

Maltese enjoy a regular walk or playing outside. They often remain playful well into old age. Because they are active indoors and don’t require a great deal of exercise, it doesn’t take a lot of effort to keep them in good shape. As a rule of thumb, wait until your Maltese puppy is 8 months old to walk very far with him, because his bones are still developing.

Let your puppy play at his own pace in your fenced yard until he is mature, and then take him to your vet for a checkup before embarking upon a regimented exercise program. Maltese definitely are housedogs and don’t tolerate extreme heat or cold well. Many people paper train their Maltese so they don’t have to take them outdoors when the weather is too hot or cold.
