UKC Terrier
Sporting Lucas Terrier.
UKC: a working terrier, to be judged as one; named for Major Sir Jocelyn Lucas, who with the Hon. Mrs. Enid Plummer crossed his hunting Sealyhams with Norfolk Terriers to produce a small, workmanlike terrier 'designed to work in a pack and push game out of thick cover'; today maintained primarily as a working terrier in Great Britain, used to hunt ground vermin and go to ground when required. Terrier World (founder's account): Sir Jocelyn wanted terriers that would go to ground and also hunt as a pack, pushing game from cover toward waiting guns; the Sporting Lucas Terrier Club was formed in 1999 by owners of the 'Raggengill' type bred with Dr Brian Plummer, after a divide with the Lucas Terrier owners over show-type build; Col. David Hancock drew up the club's standard, and a separate 'Hancock line' register takes progeny of a Norfolk Terrier outcross (no more than 50% Norfolk). The club chose UKC over the Kennel Club because UKC caters to functional working dogs. Wikipedia: developed in Scotland from the Lucas Terrier, Jack Russell Terrier and Fell Terriers by Brian Plummer in the 1990s, with a 'tenuous' link to the original Lucas Terrier (uncited); only UKC recognizes it among the major English-speaking clubs. Showsight (2026): the traditional Lucas Terrier should not be confused with the Sporting Lucas, which broke off partly under Plummer's influence when Jack Russell Terriers and other breeds were introduced, and has its own club..
Breed sets the odds. The parents set the dog. Every number here shows its source, its spread and how sure we are. Nothing on this page is a prediction about one dog.
The body
What the breed is built like. Registry standards give an ideal, not a range.
Height at the shoulder
UKC prints a desirable range, so center is blank.
Weight
The UKC and the club founder's account differ at the top (15 versus 13 lb); both stand. Center blank.
Coat
UKC standard; the club account and Wikipedia agree on a harsh coat.
Heat tolerance
Derived from the UKC coat description (medium-length double coat = 3 on the ruled scale). No measured data.
The dog at home
What the breed asks of a day. The first thing most homes get wrong.
Energy
UKC standard only.
The work
What it was built to do in the field, and what a test or trial asks of it.
Role
The sources disagree on the breed's origin (UKC: Sir Jocelyn Lucas and Enid Plummer; Wikipedia and Showsight: Brian Plummer in the 1990s; Terrier World: a split in the Lucas Terrier Club). All stand. The Sporting Lucas Terrier is not the traditional Lucas Terrier.
Primary game
UKC states no species; the club founder's account names rats, mink and fox.
Also used on
Single club-side account.
Search pattern
UKC states voice (not prone to give tongue without reason); pack versus single comes from the UKC history and the club account.
How common the problems are
Evaluated dogs skew toward breeding stock; the numbers are still the best there are.
Most common disorders
Club statement, undated, not a survey.
What to ask a breeder for
The health clearances the breed’s own club and registry name. Reference only: what to ask for, never a statement about any dog’s health.
