Portuguese Water Dog puppy growth: milestones and weight estimates
How fast a Portuguese Water Dog puppy grows, illustrative weight estimates and the limits of predicting adult size.
Porties reach close to adult height by around twelve months and keep filling out through the chest until about 18 to 24 months. Growth is steady rather than dramatic, and a balanced diet for medium breeds is usually enough. Keep a puppy lean: carrying extra weight during growth puts extra stress on developing hips.
Between about six and ten months the soft puppy coat gives way to the adult coat, and matting can appear almost overnight during this change. Brush more often in this window. Puppies are also notoriously mouthy, so supply plenty of chew items and redirect gently every time teeth land on skin.
