Why is my Maltese losing weight fast?
If your Maltese is dropping pounds quickly, the cause is often medical. Dental disease is the top reason small breeds lose weight – they stop eating due to mouth pain. Other culprits include gastrointestinal parasites, pancreatitis, kidney disease, or even diabetes. Since rapid weight loss in a Maltese can signal a serious condition, schedule a vet visit promptly. In the meantime, here’s what to look for and how to help.
Common causes of rapid weight loss in Maltese
Dental disease
Maltese are prone to tooth decay and gum infection. Bad breath, drooling, or pawing at the mouth are red flags. A diseased mouth makes chewing painful, so your dog may avoid food even if hungry. Check for broken teeth or red gums. A vet dental cleaning can resolve this.
Parasites
Roundworms, hookworms, or giardia can steal nutrients despite a normal appetite. Scour the stool for worms or blood. A fecal test is the only way to rule this out. Deworming medication is simple and effective.
Pancreatitis
Rich treats or table scraps can trigger pancreas inflammation. Symptoms include vomiting, diarrhea, and a hunched back. Maltese have sensitive digestion; avoid fatty foods. If pancreatitis is suspected, the vet may prescribe a low-fat diet and medication.
Other systemic issues
Kidney disease, diabetes, or hyperthyroidism (rare in dogs) can cause weight loss with increased thirst and urination. Cushing’s disease might show a pot-bellied appearance. Bloodwork is needed for diagnosis.
What to do if your Maltese is losing weight
- Inspect mouth – Gently lift lips to check for broken teeth, redness, or swelling.
- Monitor appetite – Is your dog still hungry but not eating? Or not interested at all?
- Check stool – Look for worms, blood, or diarrhea.
- Weigh weekly – Use a kitchen scale or baby scale for accuracy. A 5% loss in a month is alarming.
- Review diet – Have you switched food recently? Some Maltese react to new proteins.
When to see the vet immediately
- Weight loss >10% in a few weeks
- Vomiting, lethargy, or weakness
- Loss of appetite for more than 24 hours
- Visible pain when eating or defecating
How to support your Maltese until the vet visit
- Offer small, frequent meals of bland food (boiled chicken and rice) if they’ll eat – but only after checking for pancreatitis.
- Ensure fresh water always; if dehydrated, offer unflavored Pedialyte in small amounts.
- Keep a log of symptoms, appetite, and weight to share with the vet.
While waiting for an appointment, don’t try home remedies for serious symptoms. For example, if your dog has pancreatitis, any food can worsen inflammation. Always follow your vet’s guidance.
Preventing future weight loss in Maltese
- Daily tooth brushing with dog-safe toothpaste.
- Yearly fecal exams and deworming.
- Stick to a high-quality, low-fat diet formulated for small breeds.
- Avoid table scraps and high-fat treats.
- Regular wellness checkups every 6 months for seniors.
By staying proactive about dental care and nutrition, you can catch issues early. But when rapid weight loss occurs, don’t wait – consult your veterinarian for a thorough workup.
Key Takeaway
Rapid weight loss in a Maltese is often due to dental disease or parasites – schedule a vet visit promptly and avoid home remedies until a diagnosis is made.
