The Old English Sheepdog — the “Bobtail” — is one of Britain’s most iconic breeds. Their abundant shaggy grey-and-white coat, characteristic bear-like rolling gait, and gentle, clownish personality have made them a beloved image of British country life. Originally developed as drovers’ dogs for herding livestock to market, today they are primarily family companions — and they bring an enormous amount of character (and grooming requirement) to the role. They also carry a specific set of testable genetic conditions that responsible breeders should screen for.

Health — Key Conditions
Cerebellar Ataxia (HA)
A hereditary neurological disorder affecting the cerebellum (the brain region controlling coordination and balance):
- Caused by a mutation in the RAB24 gene
- Inheritance: autosomal recessive — DNA test available
- Symptoms onset between 5 months and 4 years: unsteady “drunken” gait, stumbling, head bobbing, difficulty with precise movements, falling
- Progressive — affected dogs deteriorate over time. There is no treatment
- Ask breeders for RAB24 DNA test certificates for both parents. Clear × carrier is safe; carrier × carrier must not be done
Progressive Retinal Atrophy (PRA)
Inherited retinal degeneration causing progressive vision loss:
- Clinical signs typically appear around 4 years: night blindness progressing to total blindness by approximately 8 years
- Annual eye tests recommended for all breeding dogs through the BVA/KC Eye Scheme
- No treatment — dogs adapt well to gradual vision loss in familiar environments
Exercise-Induced Collapse (EIC)
A genetic disorder (DNM1 gene mutation) causing collapse after intense exercise:
- Symptoms: hindlimb weakness, wobbling, incoordination, and sometimes full-body collapse after 5–15 minutes of vigorous activity — especially in warm weather or with high excitement
- Episodes typically resolve within 15–30 minutes; affected dogs are completely normal at rest
- Inheritance: autosomal recessive. DNA test available
- Management: avoid sustained vigorous exercise; moderate activity is well tolerated
Hip Dysplasia
BVA/KC hip scoring recommended for all breeding dogs. Maintain lean body weight and manage puppy exercise (avoiding high-impact activity until 18 months).
The Grooming Reality — The Most Important Practical Consideration
This is the section that determines whether an Old English Sheepdog is right for you:
- Full-coat maintenance: Daily brushing (30–60 minutes) to prevent matting. Neglected OES coats mat to the skin within weeks, causing painful skin infections, restricted movement, and welfare concerns
- Professional grooming: Every 6–8 weeks; sessions take 2–3 hours and cost £80–£120
- Many pet owners keep a “puppy clip” — a shorter manageable style that dramatically reduces daily maintenance while keeping the breed’s character. This is the practical compromise most pet homes adopt
- Annual grooming cost (full coat): £600–£1,000+
- If you are not prepared for either daily brushing commitment or regular professional grooming, this breed is not appropriate — neglected coats cause genuine suffering
FAQs
Is the Old English Sheepdog a rare breed now?
Increasingly so, unfortunately. KC registrations have declined significantly over recent decades — in 2026 fewer than 100 puppies were registered quarterly, placing the breed on the KC Vulnerable Native Breeds list at various points. The primary reason cited is the grooming commitment; as dog ownership demographics have shifted towards lower-maintenance breeds, OES numbers have fallen. This makes finding reputable, health-testing breeders even more important — and supporting the breed’s future through responsible ownership.
