Eczema in Dogs: Causes, Symptoms & Treatment

Eczema in dogs is a common skin condition that can cause discomfort and irritation. The condition can manifest in various ways, depending on the underlying cause and its severity. In this article, we discuss the symptoms, causes and treatment options for eczema in dogs.

Symptoms of Eczema in Dogs

Dogs with eczema often display a number of specific symptoms, which can vary in severity. It is important to recognise these symptoms early on to prevent further complications.

• Itching: Dogs with eczema often experience intense itching, causing them to scratch, bite or lick the affected areas excessively.
• Redness: The skin may look red, irritated and inflamed.
• Swelling: Swollen patches may develop as a result of inflammation in the skin.
• Scabs and rashes: Eczema can manifest as rashes or scabs on the skin, indicating prolonged skin irritation.
• Hair loss: Constant scratching or licking can lead to hair loss in the affected areas.
• Pus or blood: In severe cases, the skin may break open and discharge pus or blood, especially if the dog continues to scratch the affected areas.

Causes of Eczema

Eczema in dogs can be caused by various factors. Here are the main causes:

1. Food allergies

Allergies to certain foods, such as beef, chicken, dairy products or soya, can cause eczema. A dog may develop an allergic reaction, leading to skin inflammation and itching.

2. Infections

Bacterial, viral or parasitic infections can irritate the skin and cause eczema. For example, a flea allergy or fungal infection can lead to skin problems.

3. Environmental allergies

Dogs can be allergic to environmental factors such as pollen, house dust mites, mould or flea bites. These allergies can cause eczema, particularly in a seasonal pattern.

4. Medication

Some medications can cause eczema as a side effect. It is important to discuss the side effects of prescribed medications with your veterinarian.

5. Chronic health problems

Conditions such as liver disease, kidney problems or intestinal inflammation can lead to skin problems, including eczema. These underlying health issues can affect the overall health of the skin.

Types of Eczema

There are various types of eczema that can occur in dogs. The distinction between dry and wet eczema is the most common.

1. Dry Eczema

Dry eczema occurs when the skin becomes dehydrated, often due to a lack of natural oils in the skin. This leads to itching, flaking and irritation. Dry eczema is common in cold, dry climates or in dogs with sensitive skin.

2. Wet Eczema (Hotspots)

Wet eczema, also known as ‘hotspots’, occurs when the skin becomes moist and infected due to constant scratching, licking or biting. These moist patches can quickly worsen and tend to become pus-filled.

Treatment of Eczema

The treatment of eczema in dogs depends on the severity and the underlying cause. It is important to consult a veterinarian for a proper diagnosis and treatment. Here are some common treatment options:

1. Skin Care

Good skin care is essential for treating eczema. Using mild, hypoallergenic shampoos or shampoos containing corticosteroids can help relieve itching and irritation. Regularly cleaning the affected areas helps prevent infections.

2. Dietary changes

If food allergies are the cause, an elimination diet may be suggested to identify the allergens. Avoiding certain proteins or ingredients can help reduce skin problems.

3. Medication

In some cases, the veterinarian may prescribe antihistamines, corticosteroids or antibiotics to reduce inflammation and treat the infection. These medicines can help to relieve symptoms quickly.

4. Probiotics

Probiotics can support gut health, which can influence overall skin health. A balanced gut flora can reduce allergic reactions and help prevent eczema.

5. Hydration and Nutrition

It is important to ensure your dog drinks enough water and is fed a balanced diet rich in essential fatty acids, such as omega-3 and omega-6. These fatty acids support healthy skin and coat.

Prevention of Eczema

Preventing eczema in dogs often focuses on minimising the factors that can trigger the condition. Here are some preventive measures:

• Keep the skin clean and dry: Regular bathing with a mild shampoo and avoiding damp conditions can help keep the skin healthy.
• Control fleas and parasites: Preventing flea bites through regular flea treatment can reduce the risk of eczema.
• Dietary control: Monitor your dog’s diet and avoid potential allergens by choosing a hypoallergenic or elimination diet.
• Regular checks: Inspect your dog’s skin regularly, especially if they are prone to allergies, and consult a veterinarian at the first sign of symptoms.

Nutritional advice for dogs with eczema

Dogs with eczema often benefit from specific dietary adjustments to alleviate symptoms and support overall skin health. Eczema can be caused by allergies, impaired gut health or environmental factors. Here are the key dietary recommendations for dogs with eczema.

Elimination Diet: Identifying Allergies

A common cause of eczema in dogs is a food allergy. By following an elimination diet, you can determine which ingredients in the food are causing the skin reaction.

• Identifying Allergies: Common allergens in dog food include beef, chicken, dairy and grains such as wheat and maize.
• Special Food: An elimination diet involves temporarily feeding your dog hypoallergenic food that contains no known allergies. If the eczema symptoms improve, new ingredients can be gradually introduced to determine what is causing the allergies.

Example : Use food containing duck or lamb instead of beef or chicken, which can often trigger allergic reactions.

High-Fibre Nutrition: Supporting Digestion

High-fibre foods can improve gut health, which can have a direct impact on your dog’s skin health.

• Pumpkin and linseed: Pumpkin and linseed are natural sources of fibre that support bowel movements and can help balance the gut flora. This can help reduce inflammation, which is beneficial for dogs with eczema.
• Beet pulp: Beet pulp is often added to dog food due to its high-fibre content and its ability to support gut function.

Tip : Add a small amount of ground linseed or pumpkin to your dog’s daily diet.

Omega-3 Fatty Acid Supplements: Anti-inflammatory Properties

Omega-3 fatty acids have powerful anti-inflammatory properties and are highly effective in alleviating eczema-related inflammation.

• Fish Oil: Fish oil, rich in EPA and DHA (two types of omega-3 fatty acids), can support the skin by reducing inflammation and relieving itching.
• Flaxseed oil: A plant-based source of omega-3 fatty acids that is also beneficial for skin health.

Benefit : Omega-3 not only helps with eczema but also supports the overall health of the coat and the immune system.

High-Quality Proteins: The Importance of Quality in Dog Food

Dogs with eczema benefit from nutrition rich in high-quality protein. High-quality protein promotes muscle development and the repair of skin tissue.

• Meat as the Main Ingredient: Ensure your dog’s food contains high-quality meat as the main ingredient. Choose food that does not contain fillers such as maize, soya or wheat, which often cause allergic reactions.
• Protein Rotation: Vary the protein sources to minimise the risk of new food allergies.

Recommendation : Avoid cheap fillers and provide your dog with nutrition that contains a high amount of meat or fish.

Hydration: Adequate Water is Essential

Good hydration is crucial for dogs with eczema, as dehydration can exacerbate skin problems.

• Fresh water: Ensure your dog always has access to fresh, clean water.
• Wet food: If your dog isn’t drinking enough, wet food can be a good way to get extra fluids.

Pro Tip : Add a small amount of water to your dog’s dry food to encourage hydration.

Probiotics: Supporting Gut Health

Gut health plays a key role in your dog’s overall immune system, and probiotics can help maintain healthy gut flora.

• Probiotic Supplements: Probiotics can support gut flora, which is essential for a properly functioning immune system and the reduction of skin problems such as eczema.
• Fermented Food: Dog food containing fermented ingredients, such as kefir or sauerkraut, can be a natural source of probiotics.

Benefit : Probiotics can not only aid digestion but also contribute to healthier skin.

Avoid Chemical Irritants: Minimise Environmental Factors

Environmental factors can exacerbate eczema. Ensure your dog does not come into contact with chemicals that can irritate the skin.

• Natural Environment: Minimise exposure to pesticides, cleaning products and other chemicals.
• Hypoallergenic Nutrition: Avoid foods containing chemical preservatives or artificial colourings.

Tip : Choose natural, hypoallergenic cleaning products for your home and avoid strong smells near your dog.
