Maltese Breed Profile & Growth Guide

Breed Overview

The Maltese is one of the oldest toy breeds, tracing its origins to the Mediterranean island of Malta. This elegant little dog has a long, silky white coat and a personality that’s affectionate, lively, and fearless despite its small size. For centuries, Maltese have served as beloved companion animals, cherished for their gentle nature and charming demeanor.

Maltese dogs are known for their intelligence, sensitivity, and adaptability. They thrive in both apartments and larger homes and are typically friendly with children and other pets when properly socialized.

Size Category: Small
The Maltese is a small breed, typically weighing 4 to 7 lbs at adulthood. Due to their tiny frame and relatively fast growth rate, tracking their growth is essential to ensure healthy weight gain and early detection of issues such as undernourishment or developmental delays. Accurate growth tracking also helps prevent overfeeding, which can lead to obesity—a common concern in small breeds.

For more information on the breed, see the American Kennel Club Maltese profile.

How Much Bigger Will My Maltese Puppy Get?

Maltese puppies grow rapidly in the first 6 months and generally reach full adult weight by 8 to 10 months of age.

• Most Maltese puppies reach 50% of their adult weight by 3 months
• They gain weight steadily until about 8–10 months, after which growth slows significantly
• Final adult weight is typically achieved by 12 months

Rule of thumb:
To estimate your Maltese puppy’s adult weight, double their weight at 16 weeks (4 months).

Note:
Since Maltese are a toy breed, their growth curve is short and compact, unlike larger breeds that continue growing beyond the first year.

Maltese Growth Tips

Nutrition

• Feed a high-quality small-breed puppy food, ideally 3–4 small meals per day until 6 months old.
• Transition to 2 meals daily after 6 months.
• Ensure a balanced diet rich in protein, healthy fats, and DHA for brain development.
• Avoid overfeeding and limit treats to prevent obesity.

Exercise

• Despite their small size, Maltese are energetic and benefit from daily short walks and indoor playtime.
• Avoid strenuous exercise or high-impact jumping during early growth stages.
• Puzzle toys and training games offer great mental stimulation.

Health Watch

• Common growth-related concerns include hypoglycemia (especially in very small puppies), luxating patella, and dental issues.
• Monitor weight gain weekly during the first 6 months.
• Regular vet checkups, especially in the first year, can help track growth and catch issues early.
• Maintain a grooming routine—their long coat can mat easily and affect skin health if neglected.
