First-year playbook for Norwich Terrier puppy parents

When growth slows, treat drift climbs quietly.

Breed history
Where Norwich Terriers come from
Norwich Terriers were developed in East Anglia as ratters and stable companions, sharing roots with Norfolk Terriers until erect versus drop ears split the breeds.
They were bred to work close to people and go to ground when needed; courage and curiosity come in the package.
Modern Norwiches are family dogs with real terrier opinions; boredom becomes barking, digging, and creative theft.
How the Norwich Terrier calculator works
1
It uses age and current weight
The calculator uses your puppy's current age and weight to estimate adult size. Because puppies grow fastest early on and then slow down as they mature, the estimate adjusts for the stage of growth your Norwich Terrier is in.
2
It compares against typical breed growth
Norwich Terriers are usually close to full size by around 12 months. As your puppy gets older and more of its growth is already complete, the estimate usually becomes more reliable.
3
It checks the estimate against the usual range
Most adult Norwich Terriers fall within a typical weight range of 11-12 lbs. You can use the calculator for younger puppies, but estimates are usually more accurate after about 12 weeks.
