Maltese Age Calculator
One of the oldest toy breeds — Mediterranean lap dogs documented since antiquity, refined on the island of Malta and known throughout Greek and Roman times. Single-layered, non-shedding white silk coat that reaches the floor in show trim, and a temperament built specifically for human companionship. Maltese typically weigh 4–7 lb (1.8–3.2 kg) at adulthood and live 12–15 years on average.

How long do Maltese live?
Maltese typically live 12–15 years, with a median lifespan around 14 years. Small breeds like the Maltese have the longest canine lifespans. The strongest modifiable factor is body condition: dogs kept at BCS 4–5/9 (lean) routinely outlive their average by 1–2 years, while overweight dogs lose a comparable amount. Dental care from puppyhood + annual bloodwork from middle age are the next two highest-leverage longevity inputs.
Origins of the Maltese
Among the oldest of all toy breeds, with documented history reaching back over 2,800 years to Phoenician trading colonies on the central Mediterranean. The island of Malta gave the breed its name; Greek and Roman writers including Aristotle praised the small white spaniels of Melita as fashionable companions. The breed survived the fall of Rome, became a favorite of Renaissance noblewomen (Mary Queen of Scots and Elizabeth I both kept Maltese), and reached modern form through Victorian English breeders who standardized the single-layered floor-length silk coat. AKC recognized the breed in 1888. The remarkable structural consistency over millennia is unusual - most ancient breeds have been reshaped repeatedly by changing fashion.
How a Maltese ages
Compared with medium and large breeds, the Maltese's slower 4-per-year curve translates to a meaningful longevity premium. Each year of life from age 2 onward is biologically gentler. A 7-year-old Maltese reads as 44 in human terms; a 13-year-old, around 68.
A Maltese can comfortably live 15+ years given the breed's relatively flat health curve and the absence of major short-lifespan breed-typical conditions. Weight management is what actually moves the needle — a lean Maltese regularly outlives the breed average.

Maltese weight chart
Adult weight for the Maltese typically falls between 4–7 lb (2–3 kg) — placing this breed in the small breed band per AKC size classification. Weight outside this range warrants a vet conversation about body condition rather than a target weight: BCS 4–5 (a slight visible waist, ribs easily palpable but not visible) is the goal regardless of where in the breed range your individual dog lands.
| Stage | Typical weight (Maltese) | What to watch |
|---|---|---|
| 8 weeks (puppy) | ~1–1 lb | Weight gain trajectory matters more than the absolute number — track weekly. |
| 6 months | ~4–5 lb | Most small breeds at ~75% of adult by 6 months; large breeds at ~55%. |
| 12 months | ~6–7 lb | Small breeds usually fully grown. Large and giant breeds add 10-20% over the next 6-12 months. |
| Adult (12-15 mo+) | 4–7 lb | Hold steady at BCS 4-5. Excess weight directly shortens lifespan (Purina 2002 lifetime study: lean-fed dogs live ~1.8 years longer). |
Stage weights are size-band approximations using growth-curve percentiles from AAHA + Royal Canin breed-data references. Individual dogs vary ±20% from these midpoints. For a more precise current-vs-target trajectory, see the puppy growth calculator or the ideal-weight calculator.
Common health concerns to watch for
- Patellar luxation — frequent in the breed; orthopedic exam at annual visits
- Portosystemic liver shunt — congenital vascular abnormality more common in Maltese than most breeds; bile-acid screening in young dogs
- Tracheal collapse — small, soft trachea; always use a harness, never a neck collar
- Dental disease — extreme dental crowding; daily brushing or veterinary cleanings are non-negotiable
- Dental disease (small breeds are more prone)
This is general guidance based on size and breed averages. Always discuss specific concerns with your veterinarian.
Maltese life-stage milestones
Generic puppy/adult/senior bands often miss the breed-specific timing windows for orthopedic development, neuter timing, and senior protocols. The stages below are calibrated for the Maltese:
- 8 weeks (puppy arrival): Tiny - typical 8-week Maltese is under 2 lb. Hypoglycaemia risk is real: small frequent meals every 3-4 hours, never let blood sugar crash. Harness only, never a collar leash.
- 6 months (adolescence): Adult silk coat begins coming in around the face and ears. Begin daily brushing now to establish the routine; pelting starts within weeks of neglect. First dental exam.
- 1 year (young adult): Skeletally mature at 4-7 lb adult weight. Establish baseline bile-acid testing if not done as a puppy (portosystemic shunt screening). Begin annual orthopedic exam for patellar luxation.
- 3 years (prime adult): Tracheal collapse signs (honking cough on excitement) may begin. Dental disease accumulating - daily brushing or annual professional cleaning is non-negotiable on this crowded jaw.
- 8 years (mature/senior): Senior bloodwork annually. Liver enzymes deserve special attention given the breed shunt predisposition. Cataracts begin appearing. Mobility on slippery floors becomes a concern - rugs help.
- 12 years (geriatric): Many Maltese reach 14-16 years on good dental and weight management. Heart-disease screening twice yearly. Cognitive dysfunction screening as memory and routine awareness change.

Maltese age FAQ
How long do Maltese live?
Maltese typically live 12–15 years, with a median lifespan around 14 years. Small breeds like the Maltese have the longest canine lifespans. The strongest modifiable factor is body condition: dogs kept at BCS 4–5/9 (lean) routinely outlive their average by 1–2 years, while overweight dogs lose a comparable amount. Dental care from puppyhood + annual bloodwork from middle age are the next two highest-leverage longevity inputs.
How old is a 7-year-old Maltese in human years?
Using the AKC size-based method, a 7-year-old Maltese is approximately 44 human years old. Try the calculator above with your dog's actual age and months for a precise answer.
What is the typical lifespan of a Maltese?
Maltese typically live 12–15 years. A Maltese can comfortably live 15+ years given the breed's relatively flat health curve and the absence of major short-lifespan breed-typical conditions. Weight management is what actually moves the needle — a lean Maltese regularly outlives the breed average.
When does a Maltese become a senior?
As a small-sized breed, a Maltese is generally considered senior at around 10 years old. Senior status signals a shift toward semi-annual veterinary check-ups and closer monitoring for arthritis, dental disease, and weight changes.
Are Maltese long-lived?
Yes — small-breed dogs like the Maltese typically outlive larger breeds. Many Maltese reach 13–16+ years with good care.
Are Maltese really hypoallergenic?
About as close as any breed comes, with the caveat that no dog is genuinely allergen-free. The single-layered hair coat carries no undercoat to shed in clouds, and the floor-length silk tends to hold loose hair and dander rather than scatter it. But Can f 1 — the dominant allergen in saliva and skin — comes off the dog regardless of coat structure, so severely allergic owners typically still react. The price of the low-shedding coat is grooming: daily brushing to keep the silk from felting, frequent baths to manage tear-staining, and trims every 4–6 weeks. Skip the routine for two weeks and you are paying a groomer to shave a pelted dog.
