Skin allergies, also known as allergic dermatitis, are among the most frequent types of allergies affecting dogs. Your furry friend may react to a variety of irritants, leading to persistent itching, scratching, and discomfort.

Common Causes of Skin Allergies in Dogs

Several factors can trigger skin allergies in dogs. Here are three of the most common:

Flea Allergy Dermatitis

Some dogs develop an allergic reaction to flea saliva, resulting in flea allergy dermatitis. This condition causes severe itchiness, particularly around the base of the tail. You might notice red, inflamed skin, scabs, and other telltale signs of fleas like flea dirt (faeces) or even spotting fleas on your dog.

Environmental Allergens

Environmental triggers such as pollen, mold, or dust can lead to atopic dermatitis, an allergic reaction that causes skin issues. Dogs may develop seasonal allergies, manifesting during specific times of the year.

Food Allergies

Itchy skin may also point to food allergies or sensitivities in your dog. Keep an eye on your pet’s paws and ears, as scratching in these areas can be a sign, along with gastrointestinal issues like vomiting or diarrhea.

It’s essential to differentiate between food allergies and food sensitivities (intolerances). Food sensitivities develop gradually to specific ingredients like beef, chicken, wheat, or dairy, causing symptoms such as itchy skin or chronic ear infections. In contrast, true food allergies trigger an immune response that may lead to swelling, hives, or skin irritation.

Symptoms to watch for include irritation around the paws, ears, eyes, muzzle, wrists, underarms, and between the toes.

Recognising Skin Allergy Symptoms

Skin allergies in dogs can manifest in several ways, including:

• Excessive scratching or licking
• Biting or chewing the skin
• Rubbing the face or ears
• Rubbing or scooting against surfaces
• Red, irritated, or flaky skin
• Hair loss
• Sores

Severe cases can lead to secondary infections. Scratching and licking may introduce bacteria or yeast into open sores, requiring additional treatment to prevent further complications.

Treating Skin Allergies

If your dog is showing signs of skin allergies, the first step is to consult your veterinarian. They can perform allergy tests and determine the cause of the reaction. Based on the diagnosis, your vet will recommend a personalised treatment plan that may include medications, medicated baths, or other therapies.

Treatment varies depending on the underlying cause, the severity of the allergy, and its location on your dog’s body. Regardless of whether it’s an allergy, skin disease, or another condition, finding the root cause is key to providing relief and ensuring your dog feels comfortable again.
