Bernese Mountain Dog puppy growth: milestones and weight estimates
How fast a Bernese Mountain Dog puppy grows, illustrative weight estimates and the limits of predicting adult size.
Bernese puppies grow very quickly for the first 6 months, when many males weigh 25 to 32 kg, and then take a long time to finish. Most reach full height at 15 to 18 months but keep broadening through the chest and head until 2 or even 3 years. Expect a lanky, clumsy phase when the legs seem too long for the body.
Plan a Bernese puppy's activity around its stage of growth and health rather than a fixed walking allowance or a birthday deadline. Keep high-impact and forced activity out of the routine while seeking individual guidance. A new limp or painful movement deserves a veterinary call; do not wait a day or two simply because the puppy recently exercised.
