Russian Toy Growth Chart
The Russian Toy is one of the world's smallest dog breeds — a fine-boned, lively Russian companion with big upright ears and an elegant, springy trot. Once a favorite of Russian aristocracy, these tiny dogs are spirited, bright, and deeply devoted to their people. The FCI standard gives an adult weight of about 1.5-3 kg (3.3-6.6 lb), with most fully grown between 10 and 12 months.

Russian Toy weight by age
Typical male and female puppy weight ranges by age, available in lb and kg. Individual puppies may vary.
Most Russian Toy puppies approach adult weight around 9 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
Russian Toy Growth Stages
Understanding the typical growth stages helps you know what to expect as your Russian Toy 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
6–9 monthsGrowth rate begins to slow. Puppies reach sexual maturity and may test boundaries. Muscle mass develops.
Young Adult
9–12 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.
Russian Toy FAQ
How much will my Russian Toy puppy weigh as an adult?
Adult Russian Toys typically weigh between 3.3 and 6.6 lb. The breed standard does not split this range by sex, so both males and females fall in the same 3.3-6.6 lb band.
At what age is a Russian Toy 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 Russian Toy puppy weight chart?
It is a good guide, and the narrow 3.3-6.6 lb adult band keeps the target tight. 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 Russian Toy 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 Russian Toys grow differently?
The official adult range is the same for both sexes at 3.3-6.6 lb, and the difference is tiny. One growth chart serves both well.
