Old English Sheepdog Care Guide — Coat, Health & Exercise

The Old English Sheepdog — affectionately called the OES or Bobtail — is a large, shaggy herding breed weighing 27-45 kg. Behind that iconic floor-length coat is a powerful, athletic dog with a gentle temperament and a surprisingly clownish personality. But owning an OES is not casual. The coat alone is a part-time job, and the breed carries several health conditions that require informed management. This guide covers the essentials of Old English Sheepdog care from grooming to exercise to the health issues you need to know about.

Coat Maintenance — The Defining Challenge

There is no way around it: the Old English Sheepdog coat is the most demanding aspect of owning this breed. The double coat consists of a dense, waterproof undercoat and a long, shaggy outer coat that mats easily if not maintained. Prospective owners who are not prepared for this commitment should seriously reconsider.

The brushing technique matters as much as the frequency. You must brush down to the skin using a pin brush or slicker brush, layer by layer (called "line brushing"). Simply brushing the surface of the coat leaves the undercoat to mat against the skin, which causes pain, skin irritation, and can hide infections or parasites.

Health Conditions Every OES Owner Should Know

Hip Dysplasia

Hip dysplasia is one of the most common orthopedic conditions in Old English Sheepdogs. The OFA (Orthopedic Foundation for Animals) reports that approximately 19% of evaluated OES have dysplastic hips. At 27-45 kg, the breed is large enough that dysplasia causes significant mobility issues.

• Controlled growth: OES puppies should not be overfed. Rapid weight gain in puppyhood stresses developing joints. Use a large-breed puppy formula with controlled calcium.
• Joint supplements: Glucosamine and chondroitin starting from young adulthood (2-3 years) can support cartilage maintenance.
• Weight management: Keeping your OES lean is the single most impactful thing you can do for their joints. Under that massive coat, it is difficult to assess body condition visually — use hands-on rib checks regularly.
• Low-impact exercise: Swimming is excellent for OES with joint concerns. Avoid repetitive jumping or running on hard surfaces.

Autoimmune Thyroiditis

OES are predisposed to autoimmune thyroiditis, where the immune system attacks the thyroid gland. This leads to hypothyroidism — slow metabolism, weight gain, lethargy, skin problems, and coat changes. Given how much coat the OES has, coat changes from thyroid disease can be dramatic and alarming.

Symptoms to watch for include unexplained weight gain despite normal feeding, a coat that becomes dry and brittle, excessive shedding, cold intolerance, and lethargy that goes beyond the breed's normal calm demeanor. Diagnosis requires a full thyroid panel (not just T4), and treatment with levothyroxine is typically lifelong but very effective.

Exercise-Induced Collapse (EIC)

EIC is a genetic condition found in several breeds including the OES. Affected dogs experience weakness and collapse after 5-25 minutes of strenuous exercise, particularly in warm or humid conditions. The dog may appear wobbly, drag their hind legs, or collapse entirely. Episodes are typically not painful and the dog recovers within 5-30 minutes, but the condition can be life-threatening in extreme cases.

A DNA test can identify carriers and affected dogs. If your OES tests positive for EIC, exercise must be carefully managed — moderate activity is fine, but intense or prolonged exercise should be avoided, particularly in warm weather.

Primary Ciliary Dyskinesia (PCD)

PCD is a rare but serious condition in which the cilia (tiny hair-like structures lining the respiratory tract) do not function properly. This impairs the dog's ability to clear mucus from the airways, leading to chronic respiratory infections, nasal discharge, and recurring pneumonia. OES are one of the breeds with a known genetic predisposition.

There is no cure for PCD, but management includes prompt treatment of respiratory infections, keeping the dog in a clean environment with minimal dust and irritants, and ensuring good overall nutrition to support immune function. If your OES has chronic nasal discharge or cough that does not resolve with standard treatment, ask your vet about PCD testing.

Heat Sensitivity — The Hidden Danger

The OES coat is designed for cool, damp British weather. In warm climates or during summer, the massive double coat can cause dangerous overheating. This is not just a comfort issue — it is a genuine health risk.

• Exercise timing: Walk and exercise your OES early in the morning or after sunset during warm months. Midday exercise in summer is risky even in moderate climates.
• Never shave to the skin: While shorter clips are fine, shaving an OES to the skin removes the insulating layer that actually protects against both cold and heat. The coat also protects against sunburn. A 3-5 cm trim is ideal for warm weather.
• Provide cooling options: Cooling mats, kiddie pools, air conditioning, and access to shade are necessities, not luxuries, for OES owners in warm climates.
• Know the signs of heatstroke: Excessive panting, drooling, bright red tongue, glazed eyes, vomiting, or collapse. OES owners should learn to take a rectal temperature — anything above 39.5 degrees C warrants immediate cooling measures, and above 41 degrees C is a veterinary emergency.

Exercise Needs

Despite their large, shaggy appearance, Old English Sheepdogs are not couch potatoes. They are a working herding breed with moderate-to-high exercise needs — typically 60-90 minutes per day for adults. They are more adaptable than some herding breeds (they will not destroy your house if they miss a single walk), but consistent daily exercise is important for both physical and mental health.

• Daily walks: Two walks of 30-45 minutes each, at a brisk pace rather than an amble.
• Off-leash play: OES enjoy off-leash time in secure areas. They have a playful, clownish character and often invent their own games.
• Swimming: Many OES enjoy water, and swimming is ideal exercise for this breed given their joint predispositions.
• Herding and agility: The OES herding instinct is still present. Herding balls or low-level agility provide excellent mental and physical outlets.
• Puppy exercise: Follow the "5 minutes per month of age" guideline. OES grow rapidly and their joints are vulnerable during the growth period.

Nutrition Essentials

A full nutrition guide could fill its own article, but the essentials for OES owners:

• Calories: 1,300-2,000 per day for adults depending on weight and activity. Err on the lower side for less active or spayed/neutered dogs.
• Joint support: Foods with added glucosamine, chondroitin, and omega-3 fatty acids. Given the hip dysplasia predisposition, joint nutrition should start early.
• Coat support: Omega-3 and omega-6 fatty acids, zinc, and biotin. The OES coat is metabolically expensive to maintain — poor nutrition shows quickly in coat quality.
• Thyroid support: Adequate iodine and selenium for thyroid function.
• Large-breed puppy formula: Controlled calcium and calorie levels for steady, healthy growth. OES puppies should not grow too fast.
