Greater Swiss Mountain Dog puppy growth: milestones and weight estimates
How fast a Greater Swiss Mountain Dog puppy grows, illustrative weight estimates and the limits of predicting adult size.
Growth is both fast and long. Many puppies weigh 20 to 25 kg (44 to 55 lb) at four months and reach adult height by 12 to 18 months, yet the broad chest, full muscle and mental maturity arrive closer to 2.5 to 3 years.
Feed a giant-breed puppy food with controlled calcium and keep the puppy slim. Avoid long forced walks, running on hard surfaces, jumping out of cars and repeated stair climbing during the first 18 months. Ramps, short outings and play on soft ground are kinder to growing joints, and any sudden limping in a young Swissy should be checked by a vet.
