Overview
The Kerry Blue Terrier is a medium-sized Irish terrier famous for its soft, wavy coat in shades of blue. It was bred to control vermin and later became an all-round farm dog.
Intelligent, spirited and loyal, it enjoys being busy and close to its family. It is considered an endangered breed in the twenty-first century.
History
The Kerry Blue was first documented in 1847 as a bluish slate dog, often marked with darker patches and black on the legs and muzzle. It was kept to control rats, rabbits, foxes, otters and other pests, and also herded cattle and sheep.
As dog shows grew, the breed was standardised. The nationalist leader Michael Collins owned a famous Kerry Blue, and the breed was closely linked to the founding of the Irish Kennel Club, which registered a Kerry Blue first. A Kerry Blue won Best in Show at Crufts in 2000.
Appearance
A strong, well-built terrier with a long head, flat skull and deep chest. Males stand about 46 to 48 cm and weigh 12 to 15 kg, with females slightly smaller and lighter.
The coat is thick, soft and wavy, in any shade of blue, with or without black points. Puppies are born black and lighten gradually.
Temperament
Lively, alert and clever, the Kerry Blue is deeply loyal to its family and can be wary of strangers. It has typical terrier courage and can be pushy with other dogs, especially of the same sex.
It is a quick learner but needs consistent, confident training and early socialisation.
Care and exercise
It needs daily exercise and mental stimulation, such as walks, play and training games. A securely fenced garden is wise because of its chase instinct.
The coat does not shed much but needs regular brushing and professional clipping or stripping every few weeks to prevent matting and keep its shape.
Health
Spiculosis, a painful follicular condition, is found only in this breed. It is also prone to footpad keratosis and hair follicle tumours. A 2024 UK study found a median lifespan of 12.4 years.
