Giant Schnauzer puppy growth: milestones and weight estimates
How fast a Giant Schnauzer puppy grows, illustrative weight estimates and the limits of predicting adult size.
Giant Schnauzers grow rapidly in the first 6 months, then more slowly until they reach adult height at around 12 to 18 months, and they keep filling out until 2 or even 3 years. A 12-week-old puppy commonly weighs 12 to 15 kg (26 to 33 lb).
Protect developing joints by avoiding long runs, repeated jumping and full-height agility until growth plates close, at around 18 months in this breed. Adolescence can bring testing behavior, including pulling, mouthing and guarding toys or resting spots, so keep training consistent through it. Limping, reluctance to move or pain when touched should be checked by a vet.
