Cairn Terriers are generally healthy with a 13–15 year lifespan, but face inherited risks including CMO, liver shunts, PRA, and skin allergies.
Understanding Cairn Terrier health issues is important for any owner of this otherwise robust and energetic breed, which typically lives 13 to 15 years. Like most purebreds, While many Cairns live long, healthy lives with minimal issues, knowing what to watch for can make a real difference in early detection and management.
Common Genetic Conditions In Cairn Terriers
The most notable inherited condition in this breed is Craniomandibular Osteopathy (CMO), also called “Lion Jaw.” This non-cancerous bone overgrowth affects the jaw and typically appears between 4 and 8 months of age. Symptoms include jaw pain, difficulty eating, fever, and tender swelling of the lower jaw. The responsible gene mutation is SLC37A2, and inheritance is autosomal dominant with incomplete penetrance — . CMO usually resolves on its own by 12 months, with treatment focused on pain relief and dietary adjustments during the active phase.
Portosystemic liver shunts are another concern. Abnormal blood vessels bypass the liver, preventing proper toxin filtration. Symptoms include stunted growth, seizures, increased thirst, vomiting, and unsteady movement. Diagnosis typically involves urine analysis, and management may require a special diet or surgery in severe cases.
Eye disorders are also common. Progressive Retinal Atrophy (PRA) causes gradual vision loss leading to blindness with no available treatment. Cataracts can appear in younger or older dogs and are correctable with surgery. Other eye issues include glaucoma, ocular melanosis, and distichiasis — extra eyelash hairs that can cause corneal ulcers.
Skin, Joint, And Endocrine Health Concerns
Skin allergies are among the most significant health issues in Cairn Terriers. This genetic allergic reaction causes intense itching, especially on the feet and ears. Food allergies are also common. Managing skin health often requires identifying triggers and working with a veterinarian on an appropriate treatment plan. The Cairn Terrier Health Foundation offers detailed guidance on breed-specific screening for inherited conditions.
Joint problems include patellar luxation (kneecap dislocation), Legg-Calvé-Perthes disease (femoral head degeneration in puppies under one year), and hip dysplasia. Patellar luxation is particularly common in small breeds and can cause a “bunny-hopping” gait. Severe cases may require surgery. Arthritis is common in older Cairns.
Endocrine disorders are also seen at higher rates. , with symptoms like excessive eating, drinking, and urination. Hypothyroidism and Cushing’s disease are additional concerns, causing weight gain, lethargy, and coat changes or pot-belly and hair loss respectively.
| Condition | Category | Key Details |
|---|---|---|
| Craniomandibular Osteopathy (CMO) | Skeletal | “Lion Jaw”; resolves by 12 months; DNA test available |
| Liver Shunts (PSS) | Hepatic | Above-average risk in Cairns; diet or surgery needed |
| Progressive Retinal Atrophy (PRA) | Eye | Gradual blindness; no treatment available |
| Patellar Luxation | Joint | “Bunny-hopping” gait; surgery for severe cases |
| Atopic Dermatitis | Skin | Highest incidence among terriers; chronic itching |
| Diabetes | Endocrine | Above-average risk; managed with diet and insulin |
| Dental Disease | Oral | 80% of dogs by age 2; Cairns more prone |
Preventive Care Tips For Cairn Terrier Owners
Responsible prevention starts with DNA testing. Breeders should test for CMO, Krabbe Disease, MTC, and PK before breeding. For owners, routine screenings are key: annual urine analysis helps detect early kidney issues like glomerulonephropathy, yearly eye exams catch PRA and cataracts, and regular joint exams identify mobility problems early.
Diet plays a role in managing health conditions, particularly for Cairns with food allergies or sensitivities. Choosing a diet tailored to the breed’s needs can support skin health, weight management, and overall well-being.

How long do Cairn Terriers typically live?
Cairn Terriers generally live 13 to 15 years, with most reaching around 13 to 14 years. They are a robust and hardy breed overall, but regular veterinary care and preventive screening are important throughout their lives to manage breed-specific genetic risks and catch issues early.
Are Cairn Terriers prone to eye problems?
Yes, Cairn Terriers face several inherited eye conditions including Progressive Retinal Atrophy (PRA), cataracts, glaucoma, and ocular melanosis. Annual eye exams are recommended to catch these issues early, since some conditions like PRA have no available treatment and early diagnosis helps with planning and care.
