Shetland Sheepdog Lifespan & Health Guide
The typical Shetland Sheepdog lives 12–14 years, with a median of 13 years.
The Shetland Sheepdog is a small, agile herding dog that originated in the Shetland Islands of Scotland, where they were bred to herd sheep on rough terrain and guard crofters' gardens. Despite their resemblance to a miniature Rough Collie, Shelties are a distinct breed with their own unique characteristics, including exceptional intelligence, sensitivity, and a strong desire to please. They are consistently ranked among the most trainable breeds and excel in obedience, agility, and herding trials.

Common Shetland Sheepdog Health Problems
Collie Eye Anomaly (CEA)
CEA is an inherited developmental defect affecting the choroid, retina, and sclera of the eye. It is prevalent in Shetland Sheepdogs and related Collie breeds. The condition ranges from mild choroidal hypoplasia, which may not affect vision, to severe colobomas and retinal detachment that can cause blindness. CEA is present from birth and does not progress, though complications such as retinal detachment can occur. A genetic test is available to identify affected dogs and carriers before breeding.
Typical onset: 0–0.5 years
Dermatomyositis (DMS)
Dermatomyositis is an inherited inflammatory disease affecting the skin and muscles, most commonly seen in Shelties and Collies. The condition causes skin lesions, hair loss, and in severe cases, muscle wasting. Lesions typically appear on the face, ear tips, tail tip, and bony prominences of the legs. The severity is highly variable — some dogs have mild, self-limiting skin changes while others develop debilitating muscle disease. Stress, sun exposure, and hormonal changes can trigger flare-ups.
Typical onset: 0.25–1 years
Hip Dysplasia
Although the Shetland Sheepdog is a small breed, hip dysplasia occurs at a notable rate in the breed. The condition involves malformation of the hip joint, leading to instability, cartilage damage, and progressive arthritis. In Shelties, the condition is often milder than in larger breeds but can still cause significant discomfort and reduced mobility, particularly impacting their performance in agility and other athletic activities. Small breed dogs may compensate for hip pain more effectively, masking symptoms until the disease is advanced.
Typical onset: 1–5 years
Von Willebrand Disease (Type III)
Von Willebrand disease is an inherited bleeding disorder caused by a deficiency of von Willebrand factor, a protein essential for platelet adhesion and blood clotting. Shelties can be affected by Type III, the most severe form, which causes spontaneous and prolonged bleeding episodes. Affected dogs are at risk during surgery, dental procedures, or any situation involving tissue damage. The condition is autosomal recessive, meaning both parents must carry the gene for offspring to be affected.
Typical onset: 0.5–2 years
Thyroid Disease (Hypothyroidism)
Hypothyroidism is relatively common in Shetland Sheepdogs, caused by autoimmune destruction of the thyroid gland that reduces thyroid hormone production. The condition affects metabolism throughout the body, leading to weight gain, coat changes, and lethargy. In a breed known for its energy and alertness, a Sheltie that becomes sluggish and gains weight despite normal feeding should be tested immediately. The condition is easily managed with daily hormone replacement once diagnosed.
Typical onset: 4–10 years
Recommended Health Screenings
Breed-specific tests and evaluations recommended for Shetland Sheepdogs:
- CEA DNA test
- CERF/OFA ophthalmologic exam
- Hip evaluation (OFA or PennHIP)
- Von Willebrand disease DNA test
- Thyroid panel (T4, free T4, TSH)
- DMS genetic risk test
Typical Veterinary Costs
Shetland Sheepdogs are generally rated medium on the annual veterinary cost scale, based on breed-specific health risks, known chronic conditions, and typical screening requirements. Routine wellness care plus budget for breed-specific screening tests.
When Is a Shetland Sheepdog Considered Senior?
Shetland Sheepdogs are generally considered senior at around 10 years of age. At this point, you should increase vet visits to twice yearly and watch for age-related health changes.

Adult Shetland Sheepdogs need 60–90 minutes of exercise per day. Adult Shelties are versatile athletes that excel in a wide variety of activities. They need daily physical exercise combined with mental stimulation to remain happy and well-behaved. Two sessions per day are ideal — a physical exercise session and a training or enrichment session. Under-exercised Shelties become barkers and develop anxious behaviors.
Cautions: avoid exercise in extreme heat due to heavy coat; check for burrs and debris in feathering after outdoor exercise; monitor for joint stiffness after intense agility sessions
Shetland Sheepdog Diet & Nutrition
Adult Shetland Sheepdogs typically eat 0.75–1.5 cups of adult formula (small breed or all-breed) per day, split into 2 meals. Shelties are generally moderate eaters that maintain good body condition. Their food requirements are modest for their apparent size due to their small actual body weight under all that coat. A diet rich in omega fatty acids supports their abundant coat. Adjust portions based on activity level, particularly for competition dogs versus house companions.
Key nutrients: high-quality protein for lean muscle maintenance, omega-3 and omega-6 fatty acids for coat health, fiber for digestive health, antioxidants for immune support
Shetland Sheepdogs have modest appetites relative to their energy levels and are not typically prone to obesity. However, their thick double coat can easily hide gradual weight gain, making regular hands-on body condition assessments essential. Run your hands along the ribs and spine — you should feel the bones easily with a thin layer of fat covering. An overweight Sheltie puts unnecessary stress on joints that may already be susceptible to dysplasia. Adjust portions whenever activity levels change, such as after spaying/neutering or during winter months.
Shetland Sheepdog Dental Care
Shetland Sheepdogs, like many small breeds, are more prone to dental disease due to their relatively small jaws and crowded teeth. Regular dental care is essential starting from puppyhood. Shelties are generally cooperative patients for tooth brushing once accustomed to the process, as their desire to please extends to tolerating grooming routines. Daily brushing combined with annual professional cleanings can prevent the tooth loss that commonly affects small breeds in their senior years.
