Norwich Terrier size chart: crate, harness & collar

What the published charts say for a Norwich Terrier, across 19 harnesses, 6 crates and 7 collars. Every answer says how it was reached, and none of them replaces measuring your dog.

No published chest or neck girth was found for this breed. Girth is never worked out from weight or height here, so the tables below fall back to weight where a maker prints it, and say so.

These are published breed figures, not your dog. Measure your dog — chest girth for a harness, neck for a collar, length and height for a crate.

Rows marked “by weight only” had no published girth to work from, so the maker’s weight bands were used. That is the weaker route, and two dogs of the same weight can need different sizes.

Puppy?

Size for the adult and use a divider. A crate bought to fit a puppy is outgrown in weeks, and a crate with a spare end stops working as a den. Buy the adult size and move the divider back as the dog grows. A harness or collar is the opposite: buy for the dog you have now, because adult-sized straps slip on a puppy.

Is your dog a mix?

Mixes vary a lot. Measure your dog. A breed figure describes a published standard, and a mix is not held to one. Two dogs from the same litter can land two sizes apart on the same chart.

Measure your Norwich Terrier

The tables above start from a published breed range. This starts from your dog. Crates need a body length and a standing height, plus 4 in of room.

Size your Norwich Terrier

Enter what you have measured. Every answer below is the maker’s own published range against your number — a starting point, not a fitting.

No chest or neck girth is published for the Norwich Terrier, so there is nothing to compare against here.

Measure your dog and enter it. A published range is a range: the boxes below stay empty because the middle of a range is a number nobody published. Full Norwich Terrier size chart

Sizes come from each maker’s own published chart. Check the maker’s current chart before you buy: charts change, and nothing here is a guarantee of fit.

Common questions

What size harness for a Norwich Terrier?
On the charts published by their makers, a Norwich Terrier comes out at Julius-K9 IDC Powerharness Mini-Mini, Kurgo Tru-Fit Smart Harness (quick release) Small, PetSafe Easy Walk Harness Petite / Small (by weight only, which is the weaker route), with 7 of 19 charts giving a size. Size labels are not comparable between brands, so read the range rather than the letter. Measure your dog's chest girth at the widest part of the rib cage and check it against the maker's own chart before you buy.
What size crate for a Norwich Terrier?
By the makers' own weight guidance, a Norwich Terrier comes out at MidWest Homes for Pets iCrate Single Door Folding Dog Crate 22-inch or 24-inch, MidWest Homes for Pets LifeStages Single Door Dog Crate 24-inch, Petmate Sky Kennel 21". Weight is the rougher route: a crate is sized on the body. Measure your dog from the nose to the base of the tail and from the floor to the top of the head while standing, add 4 inches to each, and compare that with the crate's interior, not its outside.
How big does a Norwich Terrier get?
An adult Norwich Terrier is 10 in tall at the shoulder, 12 lb. No published chest or neck girth was found for this breed. These are breed-standard ranges, not your dog: individual dogs sit outside them. Measure your dog.
