Old English Sheepdog Autoimmune Diseases: What Every Owner Should Know
Quick answer
Is this a common health issue in the breed?
No, true autoimmune skin disease is uncommon and isn't among this breed's documented common health issues.
Sores and hair loss around the nose, eyes, or footpads that don't respond to the usual allergy or infection treatment are the pattern that should raise the question of an autoimmune cause.
This is most relevant to owners who've already been through a round or two of allergy or infection treatment without improvement, and are starting to wonder if something else is going on.

When skin sores in this breed need urgent attention
Autoimmune skin disease itself rarely constitutes a sudden emergency, but its complications can. Widespread ulceration, sores that are actively oozing or bleeding significantly, a dog that seems systemically unwell with lethargy or fever alongside skin lesions, or rapid spread over a period of days rather than weeks should prompt an urgent vet visit rather than a routine appointment.
Because the nose, footpads, and areas around the eyes are common sites for autoimmune skin disease, and these areas are more exposed and less protected by this breed's dense body coat, watch specifically for crusting, depigmentation, or sores in those spots even if the rest of the coat looks completely normal.
If any of these apply, call your vet or an emergency clinic now. The rest of this page is for the cases that are not an emergency.
What this problem looks like
Autoimmune skin disease occurs when the immune system mistakenly attacks the body's own skin cells, producing sores, crusting, or hair loss, often in a symmetrical pattern around the nose, eyes, or footpads. It is uncommon in dogs generally and is not a documented predisposition in Old English Sheepdogs, but it is frequently mistaken for allergies until it's properly diagnosed.
Common triggers
- An underlying immune dysfunction with no single identifiable external cause
- Sometimes triggered or worsened by sun exposure on the nose and face
- Occasionally associated with certain medications or vaccines, though this link is not well established
- Genetic predisposition, though not one documented for this specific breed
- Middle-aged to older dogs are more commonly affected than puppies
Uncommon overall, and not among this breed's documented common health issues. It's included here because it is frequently confused with allergies, a genuinely common issue in this breed, and getting the distinction right changes the entire treatment path.
Why this happens
Breed factors
There is no documented breed-specific predisposition to autoimmune skin disease in Old English Sheepdogs. What is specific to the breed is how the condition tends to be discovered: exposed areas like the nose and footpads aren't hidden by the dense body coat, so lesions there tend to be noticed relatively early, even when body-coat symptoms would be missed for weeks.
Environment factors
Sun exposure can worsen lesions on the nose in some autoimmune skin conditions, and general skin barrier stress from over-bathing or harsh products can make any skin condition, autoimmune or not, look worse and harder to interpret.
What you can do at home (once it is not an emergency)
When to talk to your vet
Talk to your vet if skin sores or crusting don't improve after a proper course of allergy treatment, if lesions are symmetrical or concentrated around the nose, eyes, or footpads, or if depigmentation appears on the nose or lips.
At home, alongside your vet's plan
- Photograph any nose, eye-area, or footpad sores weekly to track whether they're spreading, shrinking, or changing shape.
- Avoid harsh or unnecessary bathing while a diagnosis is pending, since over-bathing can further irritate compromised skin.
- Limit unprotected midday sun exposure if your dog has any nose or facial lesions, since sunlight can worsen some autoimmune skin conditions.
- Keep a written timeline of what's been tried so far, including allergy treatments, so your vet or a dermatologist isn't starting from zero.
- Ask your vet directly whether a biopsy is warranted if allergy-focused treatment hasn't helped after several weeks.
Mistakes that delay an autoimmune diagnosis
Because autoimmune skin disease is uncommon, it's often the last thing considered, which can mean months of the wrong treatment.
- Repeating allergy treatment when it isn't working: if a well-run allergy protocol, including diet trial and environmental management, isn't improving symptoms after several weeks, it's time to ask about other causes, not simply try the same approach longer.
- Assuming symmetrical sores are 'just a hot spot': true autoimmune skin lesions are often symmetrical, appearing in the same pattern on both sides of the face or body, which single hot spots typically aren't.
- Skipping a skin biopsy because it feels invasive: a biopsy is often the only way to distinguish autoimmune disease from allergy or infection, and delaying it delays the right treatment.
- Using over-the-counter medicated shampoos indefinitely without a diagnosis: these can mask symptoms without addressing the underlying cause, especially if that cause is autoimmune.
- Not photographing lesions over time: autoimmune skin disease often has a specific look and pattern, and photos help a vet or dermatologist track whether an area is truly new, spreading, or changing shape.

What to expect, and how you know it is working
Diagnosis typically takes several weeks, since ruling out allergies and infection usually comes first, followed by a biopsy if symptoms persist. Once treatment starts, improvement is often seen within four to eight weeks, though full control can take longer.
Success looks like lesions healing or significantly improving on treatment, with a maintenance plan to keep flare-ups controlled, since most autoimmune skin conditions in dogs are managed long-term rather than cured outright.
The nose sores that weren't allergies after all
Gus, a nine-year-old Old English Sheepdog, developed crusty sores across the bridge of his nose that his vet initially treated as an allergic reaction. Two rounds of allergy medication over six weeks didn't help, and the sores had started to look symmetrical on both sides. A referral to a veterinary dermatologist and a skin biopsy confirmed an autoimmune skin condition. With the right prescription treatment, Gus's nose healed within about two months, and his owner now watches for any recurrence as part of routine grooming checks.
Key takeaway: When a skin problem doesn't respond to allergy treatment and follows a symmetrical pattern, it's worth asking specifically about autoimmune causes rather than repeating the same approach.
Frequently asked questions
Is autoimmune skin disease common in Old English Sheepdogs?
It's uncommon in this breed specifically and in dogs generally. It's not among the documented common health issues for Old English Sheepdogs, but it's worth knowing about because it's frequently mistaken for allergies.
How is autoimmune skin disease different from allergies?
Allergies typically cause itching first and lesions second, often widespread and seasonal or food-related. Autoimmune skin disease tends to cause more localized, often symmetrical sores, crusting, or depigmentation, especially around the nose, eyes, and footpads, and it usually doesn't respond to typical allergy treatment.
How is autoimmune skin disease diagnosed?
A skin biopsy is typically required for a definitive diagnosis, since the appearance alone can overlap with allergies or infection. Your vet may also run bloodwork to rule out other causes first.
Can autoimmune skin disease be cured?
Most autoimmune skin conditions in dogs are managed long-term with medication rather than cured outright, similar in concept to how chronic allergies are managed rather than eliminated.
What does treatment usually involve?
Treatment is prescribed and monitored by a vet, often a veterinary dermatologist, and is tailored to the specific autoimmune condition identified. It is not something to attempt to manage with over-the-counter products alone.
Why does my dog's nose look pale or crusty?
Nose depigmentation or crusting has several possible causes, from sunburn to allergies to autoimmune conditions. It's specific enough that a vet exam, and sometimes a biopsy, is the only reliable way to know which one you're dealing with.
Should I be worried if my vet mentions a biopsy?
A skin biopsy is a routine diagnostic step, not a sign of an inevitably serious outcome. It's the most reliable way to distinguish between several possible causes that can look similar on the surface.

What's the key difference from ordinary allergies?
Symmetrical sores or crusting around the nose, eyes, or footpads that don't respond to allergy treatment point toward an autoimmune cause.
Health
How is it diagnosed for certain?
A skin biopsy, often combined with bloodwork, is the standard way to confirm an autoimmune skin condition.
Costs
Is treatment expensive?
Diagnosis with a biopsy and dermatology referral, plus ongoing prescription treatment, can be a meaningful recurring cost, often more than routine allergy management.
Health
Can I treat this at home with shampoo?
No. Over-the-counter shampoos may soothe symptoms temporarily but won't address an autoimmune cause and can delay proper diagnosis.
