How big are Norwich Terriers?

Norwich Terriers are small-sized dogs. Adult males and females typically weigh around 12 pounds and stand up to 10 inches tall at the shoulders. They are compact and sturdy dogs, similar in size to other small terrier breeds such as Cairn Terriers and Norfolk Terriers. 

Several factors can influence the size of your Norwich Terrier. Genetics play a significant role, as dogs from larger or smaller parents may inherit their size traits accordingly. Nutrition during growth stages also impacts their size and overall health. It’s important to feed small-breed puppy food until they are six to eight months old, as this diet is formulated to support healthy and balanced development.
