Old English Sheepdog Allergies: What Every Owner Should Know
Quick answer
What's the most common sign of allergies in this breed?
Recurring ear infections are usually the first and most persistent sign, even before obvious skin symptoms appear.
If your Old English Sheepdog is shaking their head constantly, chewing at their paws, or back at the vet for another ear infection, chronic allergies are the most likely explanation.
This wears down owners who assumed one course of ear drops or one food switch would be the end of it. Because this breed's coat and ear structure both trap moisture and allergens, allergies here tend to be a long, low-grade management project rather than a one-time fix.

What this problem looks like
Chronic allergies in Old English Sheepdogs are usually a combination of environmental and food sensitivities that show up as recurring ear infections, paw licking, and skin irritation. Because the breed carries a dense double coat and heavy ear leather, symptoms tend to be persistent rather than a single flare that resolves and disappears.
Common triggers
- Seasonal pollen, grasses, and mold spores
- Dust mites in household bedding and carpet
- Specific food proteins or grains
- Trapped moisture under a long or matted coat
- Fleas and other external parasites
Allergies are one of the most frequently reported chronic issues across dog breeds generally, and this breed's grooming demands mean symptoms, once present, are often harder to fully resolve than in a short-coated dog.
Why this happens
Breed factors
There's no single gene or documented breed-wide allergy predisposition unique to Old English Sheepdogs, but the physical structure of the breed works against easy management: heavy ear leather traps warm, moist air against the ear canal, and a thick double coat holds allergens and moisture against the skin longer than a short coat would.
Environment factors
Seasonal pollen, indoor dust and mold, and flea exposure all act as environmental triggers. Because this breed needs frequent bathing to manage the coat, product buildup and incomplete drying after baths can also contribute to skin irritation if the undercoat isn't dried thoroughly.
What you can do at home (once it is not an emergency)
When to talk to your vet
See your vet if ear infections recur more than two to three times a year, if skin irritation doesn't improve with basic home care within a week or two, or if you notice hair loss, open sores, or a strong odor from the skin or ears.
At home, alongside your vet's plan
- Set a consistent ear-cleaning schedule with a vet-approved solution rather than only cleaning when infections flare.
- Keep the coat around the ears, paws, and skin folds trimmed and free of mats to reduce trapped moisture.
- Run an eight- to twelve-week elimination diet trial under vet guidance if food allergy is suspected, with zero treats or table scraps during the trial.
- Use a good undercoat rake after baths and dry the dog fully, including the undercoat, to avoid leaving damp skin under the topcoat.
- Keep a simple symptom log noting flare-ups against season, food changes, and grooming products to help your vet spot patterns.
Mistakes that make chronic allergies worse
Long-running allergy cases usually aren't caused by one big error, but by a handful of small, repeated ones.
- Treating each ear infection in isolation without addressing the allergy driving it: the infection clears, then returns in six to eight weeks because the underlying cause was never managed.
- Switching dog foods repeatedly without a real elimination trial: constant food changes make it impossible to identify an actual food trigger and can upset digestion on top of the allergy.
- Bathing too often with the wrong product in an attempt to 'wash away' allergens: over-bathing can strip natural oils and worsen the skin barrier, especially with a coat this dense.
- Letting the coat around the ears and paws grow matted: trapped moisture and debris under mats is a direct contributor to the skin and ear infections that come with allergies in this breed.
- Skipping the follow-up vet visit once symptoms improve: allergy management is about staying ahead of flare-ups, not stopping treatment the moment things look better.
- Assuming it's 'just allergies' without ever getting an actual diagnosis: some skin issues that look allergic are something else entirely, like a mite infestation or a hormonal skin condition tied to this breed's documented hypothyroidism risk.

What to expect, and how you know it is working
Expect a few weeks to see meaningful improvement after starting a management plan, and longer if a food trial is involved. Seasonal environmental allergies tend to flare and settle with the calendar rather than disappearing for good.
Success looks like ear infections dropping from several times a year to rare or none, calmer skin, and a maintenance routine that fits into normal grooming rather than feeling like a constant crisis.
What long-term allergy management actually looks like
Chronic allergies in this breed are rarely solved outright; they're managed. That means a maintenance routine rather than a single treatment. For environmental allergies, this often includes regular ear cleaning, keeping the coat around the ears trimmed short enough to allow airflow, and using a vet-recommended skin or ear product on a schedule rather than only when symptoms flare.
For suspected food allergies, a proper elimination diet trial run under veterinary guidance, using a single novel or hydrolyzed protein source for eight to twelve weeks, is the only reliable way to confirm a food trigger. Random food switching without a structured trial almost never gives a clear answer.
Because this breed's ear canals and facial coat trap moisture particularly well, ear infections are often the first and most persistent sign of an allergy flare, even when the skin elsewhere looks fine. Owners who treat recurring ear infections as a standalone problem, rather than a symptom of allergies, tend to end up back at the vet every few months without ever getting ahead of it.
Winston's fourth ear infection in a year
Winston, a seven-year-old Old English Sheepdog, had been treated for ear infections four times in twelve months, each time with drops that cleared things up for a few weeks before the head-shaking started again. His owner finally asked for a referral to a vet dermatologist, who pointed out that no one had ever addressed why the infections kept coming back. An elimination diet trial identified a food sensitivity, and a revised grooming routine kept the hair around his ears trimmed and dry. Combined with a regular ear-cleaning schedule, Winston went from four infections a year to one mild flare the following season.
Key takeaway: Treating the ear infection without addressing the allergy behind it just resets the clock until the next flare. Long-term management, not repeated one-off treatment, is what actually breaks the cycle.
Frequently asked questions
Why does my Old English Sheepdog keep getting ear infections?
Recurring ear infections are one of the most common signs of an underlying allergy in this breed. The ear canal and the hair around it trap moisture and allergens, creating conditions where yeast and bacteria thrive, and each infection tends to return until the allergy itself is managed.
How do I know if it's a food allergy or an environmental one?
Environmental allergies tend to be seasonal or tied to specific settings, while food allergies usually cause year-round symptoms regardless of season. A structured elimination diet trial under your vet's guidance is the most reliable way to tell the two apart.
Can allergies in this breed be cured?
Most chronic allergies are managed rather than cured. The realistic goal is fewer, milder flare-ups and longer stretches of comfortable skin and ears, not permanent elimination of the underlying sensitivity.
Is grooming really connected to allergy symptoms?
Yes. A matted or overly long coat around the ears, paws, and skin folds traps moisture and allergens against the skin, which can turn a mild allergy into a persistent infection. Keeping the coat maintained is part of allergy management, not separate from it.
What does a vet-recommended allergy elimination diet involve?
It typically means feeding a single protein and carbohydrate source the dog has never eaten before, or a hydrolyzed prescription diet, with absolutely no other treats or table food, for eight to twelve weeks to see whether symptoms resolve.
Are Old English Sheepdogs more prone to allergies than other breeds?
There's no strong documented breed-wide predisposition specifically to allergies in this breed, but the combination of a dense double coat and heavy ear leather means allergy symptoms, once present, tend to be harder to keep under control than in a short-coated dog.
Could my dog's skin problem be something other than allergies?
Yes. Mite infestations, ringworm, and hormonal conditions like hypothyroidism, which is a documented issue in this breed, can all look similar to allergic skin disease. A vet visit with skin scraping or bloodwork rules these out before you commit to long-term allergy management.
How often should I clean my Old English Sheepdog's ears if they have allergies?
This varies by dog and should be set with your vet, but many allergy-prone dogs in this breed do well with a weekly cleaning schedule using a vet-recommended solution, more often during an active flare.
Quick answers

How often should I groom an allergy-prone Old English Sheepdog?
Weekly brushing at minimum, with particular attention to the ears, paws, and any skin folds where moisture and allergens can get trapped.
Health
Are chicken and grain the main food allergy culprits?
They're common culprits across dogs generally, but the only way to know for a specific dog is a structured elimination trial, not guessing based on general lists.
Costs
What should I budget for ongoing allergy management?
Expect recurring costs for ear cleaning solutions, vet rechecks, and possibly a prescription diet, which together often run more over a year than a single acute treatment would.
Behavior
Can allergies affect my dog's behavior?
Chronic itchiness and ear discomfort can make a dog more irritable, less tolerant of handling around the ears and face, and more restless at night.
