Maltese Health Problems: Symptoms and When to Worry
The most common Maltese health problems are portosystemic shunt, white dog shaker syndrome, and dental disease. Maltese typically live 12–15 years. This page is organized by symptom, so you can jump straight to digestive, neurological, dental, and joint problems, see what each one looks like in a Maltese, and know whether it is a vet visit this week, a vet visit today, or an emergency right now.

Quick answer: when to worry about your Maltese
Go to an emergency vet now if you see any of these:
- Stomach and digestive: Retching that produces nothing, a swollen tight belly, and restlessness are the signs of bloat, a true emergency. Blood in vomit, black tarry stools, or a pet that has stopped eating and passing droppings altogether also needs a vet now.
- Neurological: A seizure lasting more than five minutes, several seizures in a row, or sudden paralysis is an emergency.
- Dental: Refusing food entirely, facial swelling, or a fractured tooth with exposed pulp needs a vet within a day.
- Joint, back, and mobility: Sudden inability to use the back legs, dragging the hindquarters, or crying out when touched along the spine is an emergency. A ruptured disc has a window of hours for the best outcome.
- Any pet: collapse, seizures lasting more than five minutes, uncontrolled bleeding, or an inability to stand.
Book a vet visit this week if you see any of these:
- Stomach and digestive: Vomiting or diarrhea lasting more than 24 hours, refusing food for more than a day, or unexplained weight loss.
- Neurological: A first seizure, a head tilt, wobbliness, or a behavior change that came on over days.
- Dental: Bad breath, drooling, dropping food, chewing on one side, or red gums.
- Joint, back, and mobility: Limping for more than a day or two, stiffness after rest, reluctance to jump or climb stairs, or a change in gait.
Keep watching if: the change is mild, your Maltese is still eating, drinking, and moving normally, and it resolves within a day or two. Write down what you saw and when; a dated list is the most useful thing you can bring to a vet.

Genetic factors

What Maltese usually die from
Knowing what typically ends a Maltese's life is not morbid. It tells you which of the symptoms above deserve the fastest response.
- Age-related decline (about 40%): Many live to old age.
- Heart disease (about 20%): Mitral valve disease.
- Cancer (about 15%): Various cancers.
- Liver disease (about 10%): Including shunts.
When it may be time: from managing symptoms to saying goodbye
Some of the conditions above (portosystemic shunt) are managed for years. Each one, though, has a point where treatment prolongs the decline rather than the life. If you are reading this page because your Maltese is older and the bad days are starting to outnumber the good, that is worth saying plainly: you may not be looking for a diagnosis anymore. You may be looking for permission.
Signs the balance has shifted in a Maltese:
- Coughing worsening
- Unable to exercise
- Loss of appetite
- No longer grooming

If you are weighing costs and options, the pet end-of-life services guides by city cover in-home euthanasia and cremation prices, and the coping with losing a Maltese guide is there for afterward.

If this has stopped being about symptoms
Many people land here when their Maltese is old or ill and they are trying to work out whether what they are seeing is the end. If that is you, the health details above matter less than the question underneath them.
