At a glance
- Labradors are genetically prone to allergies due to high immunoglobulin E production, with environmental and flea allergies being most common
- Watch for persistent scratching around ears, paws and face, plus recurrent ear infections as key warning signs

You might notice your Labrador scratching more than usual, especially around the ears and paws. Many Labradors initially dismiss this as normal dog behaviour, but persistent itching in Labradors often signals something more significant. These dogs are particularly susceptible to allergies due to their immune systems producing elevated levels of immunoglobulin E, which triggers histamine release and leads to the inflammation and irritation you're observing.
Understanding what you're seeing is the first step toward helping your dog find relief. Allergies in Labradors typically affect the skin, ears, and sometimes the respiratory system, creating a cycle of discomfort that can significantly impact their quality of life.
Recognising allergy symptoms in your Labrador
The signs of allergies in Labradors are often unmistakable once you know what to look for. Persistent itching, scratching, biting, or licking, particularly around the ears, paws, face, and groin area, represents the most common indicator. You'll likely notice your dog targeting these areas repeatedly throughout the day.
Red, inflamed skin often accompanies the scratching, sometimes progressing to hair loss and hot spots where your dog has focused their attention. Recurrent ear infections serve as a hallmark sign in many Labradors, often presenting as a musty odour, head shaking, or dark discharge from the ears.
While less common, some dogs develop respiratory symptoms including runny nose, watery eyes, and sneezing. If food allergies are present, you might observe gastrointestinal signs such as vomiting or diarrhoea alongside the skin symptoms.
Watch for acute reactions that require immediate veterinary attention. Facial swelling, hives, or difficulty breathing represent emergency situations that need prompt professional care.
Understanding the types of allergies affecting Labradors
Environmental allergies, also called atopic allergies, rank as the second most common type in Labradors after flea allergies. These reactions to airborne allergens like pollen, dust, and mould often cause intense itching, especially on the legs, face, ears, groin, and armpits. The seasonal nature of some environmental allergies can help identify triggers, though dust and mould allergies persist year-round.
Flea allergy dermatitis represents the most frequent allergy type, triggered by an allergic reaction to flea saliva. Even a single flea can cause severe itching and skin inflammation in sensitive dogs. The reaction often extends beyond the immediate bite area, creating widespread discomfort.
Food allergies, whilst less common than environmental allergies, can cause itchy skin particularly around the ears and paws, along with gastrointestinal upset. Sometimes these allergies manifest as hives or facial swelling, making identification more straightforward.
Contact allergies develop from direct exposure to irritating substances like plastic bowls or certain fabrics, usually causing localised rashes where contact occurs. Secondary bacterial infections often develop from constant scratching and licking, requiring additional treatment beyond addressing the original allergy.
Getting an accurate diagnosis
Veterinary diagnosis typically relies on your dog's history, physical examination, and systematically ruling out other potential causes. Your vet will want to know when symptoms started, whether they're seasonal, what you've tried at home, and how your dog has responded to different treatments.
Allergy testing through skin or blood samples can identify specific environmental triggers, particularly useful for developing immunotherapy plans. However, these tests cannot definitively diagnose allergies on their own and work best as part of a comprehensive evaluation.
For suspected food allergies, an elimination diet supervised by your veterinarian represents the gold standard for diagnosis. This process requires feeding a novel protein or hydrolyzed diet for 8-12 weeks whilst strictly avoiding all other foods, including treats and table scraps.
Treatment approaches that work
Effective flea control forms the foundation of treatment for many allergic dogs. Modern flea preventatives like Frontline, Advantage, or NexGard must be used year-round, as even brief lapses can trigger reactions in sensitive dogs. Treating your home environment to eliminate flea eggs and larvae proves equally important.
For environmental allergies, reducing exposure to known triggers helps significantly. Frequent bathing with hypoallergenic shampoos removes allergens from your dog's coat, whilst HEPA filters and regular washing of bedding reduce household allergen levels.
Prescription medications offer targeted relief for moderate to severe cases. Apoquel and Cytopoint specifically target itch and inflammation, with Apoquel providing relief within 4-48 hours of administration. These medications require veterinary prescription and monitoring but can dramatically improve your dog's comfort.
Antihistamines like diphenhydramine work for mild cases, though they're generally less effective in dogs than in humans. Steroids such as prednisone provide powerful anti-inflammatory effects for severe flare-ups, but long-term use carries significant side effects and should be avoided when possible.
Fatty acid supplements, particularly omega-3s, reduce inflammation throughout the body and may lower the needed dose of other medications. These supplements work slowly, typically requiring 6-8 weeks to show full effects.
Managing food allergies effectively
Food allergy management centres on strict dietary control. The elimination diet process requires feeding only approved foods for the full 8-12 week period, avoiding all treats, table scraps, and flavoured medications that might contain triggering ingredients.
Commercial hypoallergenic diets like Royal Canin Hypoallergenic, Hill's Prescription Diet z/d, or Purina HA offer convenient options formulated specifically for allergic dogs. These diets use novel proteins or hydrolyzed proteins that are less likely to trigger reactions.
Home-cooked diets can be effective but must be nutritionally balanced and veterinarian-supervised to ensure your dog receives all necessary nutrients. Once trigger foods are identified, you can gradually expand the diet whilst avoiding known allergens.
Long-term management strategies
Immunotherapy, delivered through allergy shots or drops, offers a long-term solution for environmental allergies. Custom-made based on your dog's specific allergy test results, this treatment requires months to show improvement and represents a significant commitment, but can reduce reliance on medications over time.
Regular grooming helps remove environmental allergens before they can cause reactions. Brushing your dog frequently and wiping paws and coat after outdoor activities reduces allergen exposure. Pay particular attention to ear care, as Labradors with allergies are prone to recurrent ear infections.
Environmental modifications make a substantial difference in managing symptoms. Using ceramic or stainless steel food bowls instead of plastic, maintaining consistent humidity levels, and timing outdoor activities to avoid peak pollen periods all contribute to better allergy control.
Stress reduction plays an important role, as stress can exacerbate allergic reactions. Ensuring your dog has a calm, predictable environment with regular exercise and mental stimulation supports overall immune system health.
When professional help is essential
Persistent or severe symptoms that don't improve with initial home care warrant veterinary evaluation. Signs of secondary infection, including redness, pus, or unusual odours, require prompt professional treatment to prevent complications.
Acute allergic reactions involving facial swelling or difficulty breathing represent veterinary emergencies. These reactions can progress rapidly and require immediate medical intervention.
Before starting any new medication, particularly steroids or prescription diets, consult with your veterinarian. They can help you develop a comprehensive treatment plan tailored to your dog's specific needs and monitor for potential side effects.
Remember that allergies in dogs are typically lifelong conditions requiring ongoing management rather than one-time cures. With proper veterinary guidance and consistent care, most allergic Labradors can live comfortable, happy lives with well-controlled symptoms.
