Living with one

It has a short coat. It sheds through the year rather than in big seasonal moults. Plan on a brush once a week. It needs plenty of exercise compared with other breeds.

Size and growth

A Harrier is a medium dog, heavier than a Border Collie and lighter than a Golden Retriever. Males end up a little heavier than females.

In size and build it sits between the Beagle and the English Foxhound. It is a strong, well-boned hound with a level back, a deep chest, a broad head and hanging ears. The short, dense coat may be any colour, often white with black, tan or lemon markings.

Lifespan

No vet study has measured how long Harriers live yet. The 12–15 years shown is a general figure without a published source.

Where it comes from

The Harrier is a hound bred to hunt hare - some called it the "Hare Hound" - and the Kennel Club traces its history to at least the 13th century. It was first hunted on foot; 19th-century crosses with the Foxhound made it quicker and lighter, so packs could be followed on horseback as well. Far fewer Harrier packs exist than a century ago8.

The Harrier is a British pack hound, and its later history has been shaped more by hunting kennels than by the show ring. Most working Harriers in Britain are recorded in the stud book of the Association of Masters of Harriers and Beagles, founded in the late nineteenth century, rather than with the Kennel Club. After hunting wild mammals with dogs was banned in England and Wales in the early twenty-first century, most packs there turned to trail hunting, following a laid scent. Show Harriers are scarce on both sides of the Atlantic. It was bred to work as part of a pack, tracking hare by scent across open country and keeping up a steady pace over long distances.

Breed standard

The Harrier is judged against standard no. 295, in group 6, Scenthounds and related breeds4.

Questions people ask

General guidance for dogs rather than a measured Harrier figure: most females have a first season somewhere between six and fifteen months, and cycles then settle to roughly every 180 days. Smaller breeds tend to start earlier and larger ones later, so a medium-sized breed is most likely somewhere in the middle.
