Löwchen Growth Chart
The Löwchen — 'little lion dog' in German — is a rare, cheerful companion breed traditionally shown in a signature lion trim. Playful and loving, Löwchens were once favorites of European nobility. The FCI standard gives an adult weight of about 6 kg (13.2 lb), with most fully grown between 10 and 12 months.

Löwchen weight by age
Typical male and female puppy weight ranges by age, available in lb and kg. Individual puppies may vary.
Most Löwchen puppies approach adult weight around 11 months, although individuals may finish earlier or later.
These estimated ranges combine the breed's adult weights with a size-based growth curve. They are not measured breed-specific percentiles or health targets. Month labels are rounded approximations; use the week values for each row. How these weight ranges are calculated
Löwchen Growth Stages
Understanding the typical growth stages helps you know what to expect as your Löwchen puppy grows.
Neonatal
0–2 weeksPuppies are born with eyes and ears closed, relying entirely on their mother. Rapid weight gain occurs during this period.
Socialization
3–12 weeksEyes and ears open. Puppies begin to explore, play, and learn social behaviors. This is a critical period for development.
Juvenile
3–6 monthsRapid growth continues. Puppies become more independent, start teething, and develop coordination.
Adolescent
6–10 monthsGrowth rate begins to slow. Puppies reach sexual maturity and may test boundaries. Muscle mass develops.
Young Adult
10–12 monthsGrowth is nearly complete. Your puppy is filling out and approaching adult proportions.
Adult
12+ monthsYour puppy has reached their full adult size. Weight should remain relatively stable with proper nutrition.
Löwchen FAQ
How much will my Löwchen puppy weigh as an adult?
Adult Löwchens typically weigh about 13.2 lb. The breed standard does not split this target by sex, so the same 13.2 lb figure applies to both males and females.
At what age is a Löwchen fully grown?
Most reach adult weight between 10 and 12 months. Toy breeds mature faster than larger ones, so a puppy that has stopped gaining by its first birthday is right on schedule.
How accurate is a Löwchen puppy weight chart?
It is a good guide, and the single 13.2 lb target keeps things simple. At this size, small measurement errors matter more — use the same scale each time and weigh at the same time of day for consistency.
How much should a Löwchen puppy weigh at 12 weeks?
Check the 12-week row in the weight-by-age table above for the estimated range. If your puppy falls well outside that band, re-check the scale, the lb/kg setting, and the age entry first — a single off reading is more common than a truly unusual puppy.
Do male and female Löwchens grow differently?
The official adult target is the same for both sexes at about 13.2 lb, and the difference is tiny. One growth chart serves both well.
