How Big Do Malteses Get? Size & Growth Guide

Maltese full size: 4-7 lbs, small breed. Growth timeline from puppy to adult, weight chart, and when they stop growing.

Full-Grown Size

Malteses are a small breed, reaching 4-7 lbs at full maturity. Small breeds mature faster, typically reaching adult size by 8-12 months.

With a typical weight of 4-7 lbs and lifespan of 12-15 yrs, the Maltese requires thoughtful care tailored to their specific breed characteristics. Let's examine the important details.

Growth Timeline

While each animal has its own personality, breed-level data helps establish realistic expectations. Malteses with moderate energy levels strike a good balance between activity and relaxation.

• Size: small (4-7 lbs)
• Energy Level: Moderate
• Shedding: Minimal
• Common Health Issues: Luxating Patella, Dental Disease, Collapsed Trachea
• Lifespan: 12-15 yrs

Weight Chart by Age

Care that accounts for breed predispositions leads to earlier detection and better prevention. Malteses have particular requirements based on their small size, minimal shedding level, and genetic predispositions to luxating patella and dental disease.

Routine veterinary screenings catch many breed-related conditions at stages where intervention is most effective. With 3 known predispositions, proactive screening is particularly important for Malteses.

Male vs Female Size

The key to a happy, healthy Maltese is matching your care approach to their breed characteristics. Consistent daily activity, even in short sessions, contributes more to long-term health than occasional intense exercise.

• Provide 30–60 minutes of daily exercise appropriate to their energy level
• Feed a high-quality diet formulated for small breed dogs (400–800 calories/day)
• Maintain a occasional grooming routine
• Schedule breed-appropriate health screenings for luxating patella
• Invest in pet insurance early to cover breed-specific conditions

Factors Affecting Size

Informed ownership goes deeper than the basic care checklist for any breed. As a toy breed, the Maltese has instincts and behaviors shaped by centuries of selective breeding for specific tasks.

Many experienced Maltese owners recommend a balanced mix of physical activities and brain games.

Understanding your Maltese's instinctual drives makes enrichment more effective. Rather than generic toy rotation, tailor activities to what this breed was developed to do. Working breeds benefit from task-oriented challenges; scent-driven breeds thrive with nose work; social breeds need interactive play rather than solo activities.

When They Stop Growing

Prevention-focused care tailored to breed characteristics reduces both health risks and long-term costs. Watch for early signs of luxating patella, maintain regular veterinary visits, and keep your dog at a healthy weight — obesity exacerbates nearly every health condition Malteses are prone to.

Building a preventive care plan with your veterinarian based on breed-specific data creates a structured framework for long-term health management.

A stable daily routine serves as the foundation for behavioral wellness, reducing reactivity and stress responses. Include scheduled feeding times, exercise sessions, grooming, and quiet rest periods. Even moderate-energy breeds thrive with predictable schedules.

Preventive care reduces both emergency costs and disease severity over your pet's lifetime. Here is a general framework for your Maltese. Here is the recommended schedule:

Malteses should receive breed-specific screening for luxating patella starting at 3-5 years of age or earlier if symptoms appear. Early detection significantly improves treatment outcomes and quality of life.
