The Cairn Terrier is a compact terrier breed originating from Scotland, known for being alert, fearless, and hardy. Weighing 6–7kg and standing 25–33cm at the shoulder, they typically live 13–15 years. Cairn Terriers require moderate daily exercise and moderate grooming to maintain their dense double coat. They are well-regarded as a family breed and typically patient with children. Their adaptable nature makes them a reasonable choice for apartment living, provided their exercise needs are met.

Patellar luxation occurs when the kneecap slips out of its normal groove in the femur. It can be medial (inward) or lateral (outward) and ranges from grade 1 (occasional slipping) to grade 4 (permanent dislocation).
Typical onset: 4 months - 6 years
A portosystemic shunt (PSS) is an abnormal blood vessel that allows blood from the gastrointestinal tract to bypass the liver, preventing detoxification. Toxins accumulate in the bloodstream causing hepatic encephalopathy. Congenital shunts are hereditary.
Typical onset: Under 2 years (congenital)
PRA is a group of hereditary diseases causing progressive degeneration of the photoreceptor cells in the retina. It leads to night blindness first, followed by complete blindness. There is no treatment, but DNA tests exist for many forms.
Typical onset: 3-8 years
Hip dysplasia is a genetic condition where the hip joint doesn't develop properly, causing the ball and socket to not fit together correctly. This leads to joint deterioration, pain, and arthritis over time.
Typical onset: 1-2 years
Nutrition is a cornerstone of Cairn Terrier health. An adult Cairn Terrier weighing 6–7kg typically requires 400–500 kcal of high-quality food per day, split across two meals to support consistent energy levels and healthy digestion. Small breeds can experience hypoglycaemia if meals are skipped; regular feeding times are especially important for Cairn Terrier puppies. Always adjust portions based on your dog's individual weight, life stage, and activity level, and consult your vet before making significant dietary changes.
Full Cairn Terrier Feeding GuideThe Cairn Terrier has moderate exercise requirements. Plan for at least an hour of brisk walks, play sessions, and occasional off-lead runs every day to keep your Cairn Terrier physically healthy and mentally settled. Combining physical activity with basic obedience practice or interactive play sessions helps meet both the physical and mental needs of the Cairn Terrier. Although they can adapt to apartment living, Cairn Terrier owners without a garden should plan to provide at least an hour of outdoor exercise daily without fail.

Like all pedigree breeds, the Cairn Terrier has a number of associated health concerns. The most commonly documented include Patellar Luxation, Portosystemic Shunt, Progressive Retinal Atrophy (PRA), and Hip Dysplasia.
