When Is a Maltese Considered Senior? Age, Signs & Timeline

Maltese are a classic toy breed: small (typically 4–7 lb), long white coat, and a big personality. Because of their size and breed-specific predispositions, Maltese are generally considered "senior" earlier than many large-breed dogs. For the Maltese, plan to treat them as seniors starting around 8–9 years of age. With proper monitoring and preventive care, many Maltese live comfortably into the mid-teens (typical lifespan 12–15 years).

This article explains what "senior" means for the Maltese, how to recognize early signs of age-related disease, which conditions to watch for (and why Maltese are predisposed), and clear, actionable steps owners can take to maximize [quality of life](https://seniorpet.org/knowledge/siamese-cat-quality-of-life "Quality of Life Assessment").

Senior timeline for the Maltese: what to expect

Maltese age more rapidly on a calendar scale than larger breeds during their first years, but because they are small, they remain active into older age. Below is a practical timeline showing expected changes and recommended screening at each stage.

| Age range | Life stage | What to watch for | Recommended actions | |---:|---|---|---| | 0–2 years | Puppy/young adult | Dental crowding, congenital conditions (portosystemic shunt, luxating patella) may present | Early dental care, orthopedic monitoring, watch growth and appetite | | 3–7 years | Adult | [Dental disease](https://seniorpet.org/knowledge/siamese-cat-dental-disease "Dental Disease in Senior Pets") progressing, early orthopedic or respiratory signs may appear | Annual exams, dental cleanings as needed, weight control | | 8–9 years | Early senior (Maltese considered senior) | Increased risk of [mitral valve disease](https://seniorpet.org/knowledge/cavalier-king-charles-spaniel-mitral-valve-disease "Mitral Valve Disease Guide") (MVD), luxating patella, cataracts, dental disease, collapsed trachea, and late-presenting portosystemic shunt signs; white shaker syndrome can appear at various ages | Senior wellness panel, dental evaluation, orthopedics check, cardiology screening if murmur present | | 10+ years | Senior/geriatric | Progression of chronic disease, mobility decline, vision or hearing loss, sarcopenia | Recheck every 6 months, adjust diet, pain control, mobility aids, specialist care as needed |

Common age-related conditions in Maltese — breed-specific notes

Maltese have specific health risks that become more important as they age. Below are the conditions you should know about, with signs, diagnostics, and practical management.

Mitral Valve Disease (MVD / Myxomatous Mitral Valve Degeneration)

• Why Maltese are at risk: MVD is the most common acquired [heart disease](https://seniorpet.org/knowledge/cavalier-king-charles-spaniel-mitral-valve-disease "Heart Disease in Senior Pets") in small-breed dogs. Although some breeds (e.g., [Cavalier King Charles](https://seniorpet.org/knowledge/breed/cavalier-king-charles-spaniel "Senior Cavalier King Charles Spaniel Health Guide") Spaniel) are classic examples, Maltese frequently develop myxomatous degeneration of the mitral valve as they age.
• Signs: Heart murmur on exam, cough (especially at night), exercise intolerance, increased respiratory rate at rest, lethargy, fainting episodes in advanced cases.
• Diagnostics: Auscultation, thoracic radiographs to assess cardiac size/ pulmonary edema, echocardiography (gold standard) to evaluate valve structure and function. Baseline bloodwork (CBC/chem) before any cardiac meds or procedures.
• Treatment & monitoring: The EPIC trial supports starting pimobendan in dogs with preclinical MVD and cardiomegaly to delay congestive heart failure (ACVIM guidelines). In symptomatic dogs, diuretics (furosemide) and ACE inhibitors may be used. Consult or refer to a veterinary cardiologist for staging and therapy planning (ACVIM consensus statement on MVD).
• Practical owner actions: Have any new murmur evaluated promptly; keep a log of breathing rate at rest (normal <30 breaths/min in quiet dogs); avoid excessive salt; avoid unevaluated supplements that affect blood pressure or coagulation.

References: ACVIM consensus statements and the EPIC trial on pimobendan are relevant guideline resources for MVD management.

Luxating patella

• Why Maltese are at risk: Small toy breeds are predisposed to medial patellar luxation due to conformation and straight hind limb conformation.
• Signs: Intermittent skipping or "hobbling," sudden non-weight-bearing lameness, reluctance to jump or climb stairs, audible click possible.
• Diagnostics: Orthopedic exam, grading of luxation (I–IV), and radiographs to assess alignment and conformation. Occasionally referral to an orthopedic surgeon for advanced imaging.
• Treatment & monitoring: Low-grade luxations (I–II) may be managed conservatively with weight control, physical therapy, and joint supplements (e.g., omega-3 fatty acids, glucosamine/chondroitin—evidence limited but often helps clinical comfort). Surgical correction (trochleoplasty ± tibial tuberosity transposition) is considered for persistent lameness or higher-grade luxations.
• Practical owner actions: Keep your Maltese lean and muscular, avoid high-impact jumping (use ramps), and consult early if lameness develops.

Cataracts and other ocular disease

• Why Maltese are at risk: Older Maltese commonly develop age-related cataracts and other lens changes; as a white-coated toy breed, retinal and lens disease should be monitored.
• Signs: Cloudy eye(s), bumping into objects, decreased ability to find food or favorite toys, changes in pupil size or eyelid position.
• Diagnostics: Veterinary ophthalmic exam (including menace, dazzle, pupillary light reflexes), intraocular pressure measurement, slit-lamp exam. Referral to a veterinary ophthalmologist if cataract surgery is being considered.
• Treatment & monitoring: Not all cataracts require surgery—surgical phacoemulsification with intraocular lens implantation is curative for vision loss due to cataracts if the retina is healthy. Manage concurrent uveitis or glaucoma promptly.
• Practical owner actions: Note any vision changes early; avoid bright direct sunlight during flare-ups that cause pain; keep familiar furniture layout to help a vision-impaired dog.

Portosystemic liver shunt (PSS)

• Why Maltese are at risk: Small and toy breeds have a higher incidence of congenital portosystemic shunts. Some shunts may not be recognized until later life if the shunt is small or signs are subtle.
• Signs: Poor weight gain or muscle wasting, intermittent neurological signs (disorientation, head pressing, circling, seizures), vomiting, decreased appetite, stranguria or urinary crystals due to altered bile acid metabolism.
• Diagnostics: Pre- and post-prandial bile acids, liver enzyme panel, abdominal ultrasound, CT angiography or nuclear medicine imaging to define shunt anatomy.
• Treatment & monitoring: Medical management (protein-restricted diet, lactulose, antibiotics such as metronidazole) can control signs. Many shunts are correctable surgically (attenuation or ligation) with good outcomes—referral to a board-certified surgeon is recommended. Early identification improves outcomes.
• Practical owner actions: If your Maltese had poor weight gain as a puppy or shows neurologic episodes, ask your vet about bile acid testing. Before elective anesthesia for dentistry, request pre-anesthetic liver screening.

Dental disease (periodontal disease)

• Why Maltese are at risk: Toy breeds, including Maltese, have crowding of teeth in a small jaw, which predisposes them to periodontal disease at an earlier age than larger breeds.
• Signs: Halitosis (bad breath), visible tartar, red or bleeding gums, loose teeth, reluctance to eat hard kibble, pawing at the mouth.
• Diagnostics: Oral exam under sedation or anesthesia, periodontal probing and dental radiographs (critical—much disease is under the gumline).
• Treatment & monitoring: Regular professional dental cleaning with scaling and polishing under safe anesthesia, extraction of diseased teeth, and daily [home care](https://seniorpet.org/knowledge/pillar/home-care-guide "Senior Pet Home Care Guide") (tooth brushing is gold standard). Antiseptic rinses or chews can help but do not replace brushing.
• Practical owner actions: Brush your Maltese's teeth daily or as often as possible with canine toothpaste and a finger brush; schedule anesthesia-safe dental cleanings with pre-anesthetic bloodwork (especially important for senior Maltese due to possible MVD or liver disease). Work with your vet to balance anesthesia risk and dental disease control.

References: Veterinary dentistry guidelines (American Veterinary Dental College) emphasize radiographs and professional cleanings.

Collapsed trachea

• Why Maltese are at risk: Small-breed dogs commonly have tracheal cartilage weakening. A long history of harsh, honking cough or tracheal sensitivity is common in toy breeds.
• Signs: "Goose-honk" cough, cough triggered by excitement or pressure on the neck, exercise intolerance, respiratory distress in severe cases.
• Diagnostics: Thoracic radiographs, fluoroscopy to visualize dynamic collapse, tracheoscopy by a specialist if needed.
• Treatment & monitoring: Medical management (cough suppressants like hydrocodone, anti-inflammatories, bronchodilators), weight control, avoid collars—use a harness. In severe or refractory cases, intraluminal or extraluminal stent/surgical options may be considered by a specialty surgeon (risks exist).
• Practical owner actions: Stop using collars—use a well-fitted harness, reduce exposure to smoke and irritants, keep cool and calm during walks, and seek early vet care for persistent cough.

White shaker syndrome (Generalized Tremor Syndrome)

• Why Maltese are at risk: White shaker syndrome (also called generalized tremor syndrome) disproportionately affects small, young-to-middle-aged white-coated breeds (including Maltese).
• Signs: Rapid whole-body tremors, anxiety, elevated tail carriage, rapid onset, sometimes vestibular signs. Tremors often worsen with excitement.
• Diagnostics: Physical/neurologic exam, bloodwork to rule out metabolic causes, sometimes MRI and cerebrospinal fluid (CSF) analysis to exclude other causes. Diagnosis is often presumptive after ruling out infectious or metabolic etiologies.
• Treatment & monitoring: Rapid response to corticosteroids (e.g., prednisone) is typical, often with a tapering protocol over weeks to months. Some refractory cases require additional immunosuppressive agents.
• Practical owner actions: If your Maltese develops sudden generalized tremors, seek urgent veterinary attention. Early steroid therapy can produce quick improvement; do not attempt home remedies.

References: Clinical reports describe corticosteroid-responsive tremor syndromes in small white breeds.

Senior care checklist — practical, actionable steps

• Start senior wellness at 8–9 years: schedule a comprehensive exam including weight, body condition score, dental check, and a discussion of behavior and mobility.
• Baseline diagnostics: CBC, chemistry panel (including liver enzymes), urinalysis, and pre- and post-prandial bile acids if liver concerns exist. Consider baseline thoracic radiographs and blood pressure, and an echocardiogram if a murmur is present.
• Dental plan: Daily home brushing; professional dental cleaning with radiographs under anesthesia as indicated. Ask about sedation protocols tailored for small dogs and discuss anesthetic risk in light of cardiac or liver disease.
• Heart monitoring: If your veterinarian hears a murmur or your Maltese shows cough or exercise intolerance, ask about echocardiography and the potential role of pimobendan (per ACVIM guidance for dogs with cardiomegaly).
• Orthopedics/mobility: Maintain an ideal weight, use ramps instead of allowing jumps, incorporate short low-impact walks and controlled physical therapy exercises. Consider joint supplements after discussion with your veterinarian.
• Respiratory management: Use a harness, avoid collars that compress the neck, reduce exposure to smoke/irritants, keep humidity moderate, and treat chronic coughs early.
• Vision and hearing: Maintain predictable home layouts, consider night-lights and non-slip mats, and pursue ophthalmic referrals for progressive cataracts.
• Nutrition: Use a balanced senior or maintenance diet suitable for toy breeds with controlled calories and adequate protein; consider diets designed for joint support if mobility is declining. For Maltese with liver disease, follow veterinary dietary recommendations (protein-modified diets only under veterinary direction).
• Medication safety: Small dogs are more sensitive to dosing errors. Always use veterinary-formulated medications and double-check doses.
• Grooming: Keep long coat clipped for easier home care as dexterity declines. Regular ear and eye checks to spot tear staining, infections, or obstructive fur.
• Regular rechecks: Schedule veterinary visits at least every 6–12 months once your Maltese reaches senior status; increase frequency to every 3–6 months if chronic disease is present.

Managing multiple conditions: balancing priorities

Many senior Maltese will have more than one problem (for example, dental disease plus early MVD). Coordinated care is key:

• Prioritize life-threatening or quality-of-life issues first (heart failure, severe hepatic encephalopathy, progressive collapse of the airway).
• Use pre-anesthetic workups to safely perform needed procedures (e.g., dental cleanings) in dogs with MVD or PSS.
• Coordinate medication interactions—some cardiac meds interact with common drugs, and corticosteroids for white shaker syndrome affect blood sugar and appetite.
• Consider specialist referrals (cardiology, ophthalmology, surgery, dentistry) when diagnosis or management is complex.

When to seek immediate veterinary care

• Sudden collapse, difficulty breathing, severe coughing with blue-tinged gums, or persistent seizures.
• Sudden blindness or severe eye pain (squinting, tearing, blepharospasm).
• Sudden inability to rise, severe lameness, or collapse.
• Severe vomiting, disorientation, or tremors unresponsive to initial vet advice (possible hepatic encephalopathy or neurologic emergency).

End-of-life planning and quality-of-life considerations

As Maltese age beyond 12 years, thoughtful conversations about comfort, pain control, and quality of life are important. Tools such as validated QOL scales (e.g., HHHHHMM scale — Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, More good days than bad) can guide decisions. Work with your veterinarian to create a plan for pain management, environmental adjustments, and humane choices if disease becomes refractory.

Final practical tips checklist for Maltese owners

• Begin "senior care" at 8–9 years; schedule baseline tests and create a calendar for rechecks.
• Brush your Maltese's teeth daily; plan professional cleanings with dental radiographs.
• Use a harness (never a tight collar) to protect the trachea; treat chronic coughs early.
• Keep your dog lean and active with short low-impact walks and at-home range-of-motion exercises.
• Log resting respiratory rate, appetite changes, mobility changes, and behavior—bring the log to appointments.
• Ask about echocardiography if a murmur is detected; discuss pimobendan in patients with cardiomegaly.
• For tremors suggestive of white shaker syndrome, seek urgent evaluation—corticosteroids often produce rapid improvement.
