Life stage context
At 8 years, your Maltese is in their Adult years.
- Use annual wellness exams, dental care, and measured feeding to keep the adult baseline stable.
- Malteses usually benefit from exercise that matches their moderate energy profile.
- Start watching for the first senior-transition signs before age 9.
Next health milestone
Age 9 years: Senior wellness baseline. Malteses commonly move into senior planning around this age. Twice-yearly wellness exams become more useful.
Lifespan overview
Maltese Lifespan & Aging Overview
Average lifespan for a Maltese is listed as 12-15 years, with a midpoint near 13.5 years. Compared with all dogs, this places the breed in the context of small-breed aging rather than a one-size-fits-all curve. Small breeds often live longer than large dogs and may stay in the adult stage for more calendar years, but dental and cardiac monitoring become especially important later in life.
Malteses are considered puppy from 0-12 months, junior from 1-2 years, adult from 2-9 years, senior from 9-11 years, and geriatric from about 11+ years. These boundaries are care-planning markers, not hard medical diagnoses.
Small breeds often keep adult vitality longer, but dental and cardiac monitoring become important with age. For Malteses, the breed database lists an average lifespan near 13.5 years and a senior threshold around age 9. A balanced routine makes it easier to notice real changes in recovery, appetite, and comfort.

Senior health
Common Health Issues in Senior Malteses
As your Maltese enters the senior years, the most useful habit is noticing small changes early: slower rising, reduced enthusiasm, appetite shifts, altered sleep, new lumps, coughing, dental pain, confusion, or reluctance to do normal activities. The list below is not a diagnosis. It is a practical watch-list based on this breed's size, energy profile, and common senior-care patterns.
1. Dental disease
Watch for behavior changes, comfort changes, appetite changes, and trends over time. Bring notes, photos, videos, and weight history to your veterinarian so subtle changes are easier to evaluate.
2. Patellar luxation or knee discomfort
Watch for behavior changes, comfort changes, appetite changes, and trends over time. Bring notes, photos, videos, and weight history to your veterinarian so subtle changes are easier to evaluate.
3. Heart murmur monitoring
Watch for behavior changes, comfort changes, appetite changes, and trends over time. Bring notes, photos, videos, and weight history to your veterinarian so subtle changes are easier to evaluate.
4. Cognitive change, anxiety, or altered sleep patterns
Watch for behavior changes, comfort changes, appetite changes, and trends over time. Bring notes, photos, videos, and weight history to your veterinarian so subtle changes are easier to evaluate.
5. Kidney, thyroid, or liver changes found on senior lab work
Watch for behavior changes, comfort changes, appetite changes, and trends over time. Bring notes, photos, videos, and weight history to your veterinarian so subtle changes are easier to evaluate.
Senior care guide
Caring for a Senior Maltese
Diet adjustments usually start with measured portions, enough protein to preserve muscle, and careful calorie review if activity drops. Calmer seniors can gain weight quietly, so routine weigh-ins become high value.
Exercise should shift toward repeatable low-impact movement: shorter walks, gentle play, swimming when appropriate, and traction-friendly surfaces. Avoid making a senior dog prove toughness through long hot walks, jumping, or slippery floors.
Vet care should usually move from annual to twice-yearly wellness visits around age9. Ask about dental comfort, pain scoring, baseline lab work, lumps, heart and lung sounds, mobility, and medication safety.

Maltese age calculator FAQ
How long do Malteses live?
Malteses usually live about 12-15 years, with an average near 13.5 years in this breed database. Small breeds have different aging patterns than toy, small, large, and giant dogs, so breed context is more useful than a universal dog-age chart.
At what age is a Maltese considered senior?
A Maltese is treated as senior around age 9 in this calculator. That does not mean every dog becomes frail on that birthday. It means wellness exams, bloodwork discussions, dental checks, weight review, mobility tracking, and early pain detection become more important.
What health problems do senior Malteses have?
Senior Malteses commonly need closer monitoring for Dental disease, Patellar luxation or knee discomfort, Heart murmur monitoring. Individual risk still depends on genetics, body condition, activity, dental care, preventive medicine, and previous injuries, so use this list as a discussion starter with your veterinarian.
How do I calculate my dog's age in human years?
The old multiply-by-7 rule is too simple because dogs age quickly early in life and then slow into a different curve. This page uses a breed-specific curve based on lifespan, size class, senior age, and age interpolation so the result is more useful than a generic chart.
Is 10 old for a Maltese?
A 10-year-old Maltese is about 74% through the breed's average lifespan of 13.5 years and is usually in the senior stage. At this point, comfort, mobility, appetite, dental health, and good-day balance matter more than the birthday number alone.

Breed lifespan and weight ranges are drawn from the site's shared breed database. Age conversion is an educational estimate that combines breed size, breed-average lifespan, and senior-stage timing. Use it for planning conversations, not as a clinical diagnosis. For medical decisions, your veterinarian and breed-specific health screening guidance remain the source of truth.
