Managing Allergic Skin Disease in Dogs
Signs, Causes and Long Term Management
Allergic skin disease is one of the most common chronic skin conditions affecting dogs in the UK. It is often linked to an inappropriate immune response to environmental allergens such as pollen, dust mites, mould spores or other substances in the dog’s surroundings.
This immune response causes inflammation within the skin, leading to itching, licking, chewing, redness and recurrent skin or ear problems. Many dogs require long term management rather than a single short course of treatment.
Clinical signs commonly include persistent scratching, paw licking, recurrent ear infections, skin inflammation, hair loss and discomfort.
Common Signs of Allergic Skin Disease
- Persistent scratching
- Paw licking or chewing
- Red or inflamed skin
- Recurrent ear infections
- Hair loss
- Scabs or sores
- Greasy or flaky skin
- Rubbing the face or body
- Skin odour
- Recurrent bacterial or yeast infections
Signs may be seasonal in some dogs, while others are affected all year round. The pattern can depend on the underlying triggers and whether secondary infection is present.
What Causes Allergic Skin Disease?
Allergic skin disease can have several underlying causes. Some dogs are affected by one main trigger, while others have multiple contributing factors.
Environmental Allergens
Pollens, dust mites, mould spores and other environmental allergens can trigger skin inflammation in susceptible dogs.
Food Related Triggers
Some dogs may have adverse food reactions that contribute to itching, skin inflammation or recurrent ear problems.
Parasites
Fleas and other parasites can cause intense itching and may worsen existing allergic skin disease.
Secondary Infection
Bacterial and yeast overgrowth are common complications and can make itching and inflammation significantly worse.
How Allergic Skin Disease is Diagnosed
Diagnosis usually involves a combination of clinical history, physical examination and investigation for common causes of itching and skin inflammation.
Your veterinary surgeon may assess for parasites, infection, food related triggers and environmental allergy. In some cases, further testing may be recommended to help guide long term management.
Approaches to Managing Allergic Skin Disease
Management is usually multimodal. This may involve reducing exposure to triggers where possible, controlling itch and inflammation, treating secondary infection and supporting the skin barrier.
The most appropriate plan depends on the individual dog, the severity of signs, the presence of infection and the dog’s response to previous treatments.
Prescription Treatment Options
Veterinary surgeons may prescribe medicines from several different treatment classes to help manage allergic skin disease. The most appropriate option depends on the individual patient, the severity of disease, concurrent health conditions and treatment response.
Commonly Used Active Substances and Treatment Classes
- Lokivetmab is a monoclonal antibody used in some dogs to help reduce itch associated with allergic skin disease.
- Oclacitinib, ilunocitinib and atinvicitinib are JAK inhibitors that may be prescribed to help reduce itch and inflammation.
- Ciclosporin is an immunomodulatory medicine that may be used in selected dogs with chronic allergic skin disease.
- Prednisolone is a corticosteroid that may be used to help control inflammation and itching, particularly during flare ups.
- Hydrocortisone aceponate is a topical corticosteroid that may be used in selected cases where localised skin inflammation is present.
All prescription treatments require veterinary assessment, prescription and ongoing monitoring where appropriate.
Topical Therapy and Skin Care
Topical therapy can be an important part of managing allergic skin disease, particularly where secondary infection, greasy skin, dryness or barrier dysfunction are present.
Medicated Shampoos
- May help manage bacterial or yeast overgrowth
- Can support skin cleanliness and comfort
- Should be selected based on veterinary advice
Skin Barrier Support
Many dogs with allergic skin disease have a weakened skin barrier. Supporting the skin barrier may help improve skin hydration, resilience and comfort.
- Helps support the natural skin barrier
- May improve hydration and skin resilience
- Can be used alongside veterinary treatment plans
Examples include skin barrier support products such as Allerderm Spot On.

Nutritional Support
Nutritional support may form part of a long term management plan for some dogs with allergic skin disease, particularly where skin barrier function, coat quality or food related triggers are involved.
- Omega 3 and omega 6 fatty acids may help support skin health
- Skin support supplements may help maintain skin barrier function
- Diet trials may be recommended where food allergy is suspected
Examples of nutritional and skin support products include Allgeze and YuMOVE Itchy Skin and Coat Care.

Long Term Management
Allergic skin disease is often a long term condition. The aim is usually to reduce itching, minimise flare ups, treat secondary infections promptly and maintain a comfortable quality of life.
Some dogs need seasonal support, while others require year round management. Regular reassessment helps ensure the plan remains appropriate as the dog’s condition changes over time.
When Should You Speak to Your Vet?
If your dog is persistently scratching, licking their paws, developing recurrent ear infections, losing hair or showing signs of skin discomfort, veterinary assessment is recommended.
Early investigation can help identify underlying causes, manage secondary infection and create a long term plan tailored to your dog.
