Norwich Terrier puppy growth: milestones and weight estimates
How fast a Norwich Terrier puppy grows, illustrative weight estimates and the limits of predicting adult size.
Norwich puppies grow quickly and are close to adult size at eight to ten months, filling out by about a year. The soft puppy coat gives way to a harsher adult coat during the first year, and the first hand-strip usually happens somewhere between six and nine months.
Keep puppies lean and limit jumps from high furniture while they grow. Early socialization with people, places and other animals is essential for a breed this bold. Book a vet visit if your puppy skips on a back leg, carries a leg off the ground, or struggles to breathe during play.
