Why Your Dog May Be Constantly Scratching?

If your dog is constantly scratching, licking their paws, or rubbing their face, allergies may be the cause. One of the most common allergic skin conditions in dogs is atopic dermatitis, sometimes called environmental allergies.

Atopic dermatitis occurs when a dog’s immune system overreacts to substances in the environment such as pollen, dust mites or mold. These allergens are normally harmless, but in sensitive dogs they trigger intense itching and skin inflammation.

This condition is very common and often begins when dogs are between one and three years of age.

What Is Atopic Dermatitis in Dogs?

Atopic dermatitis is a type of allergic skin disease caused by environmental allergens.

Common triggers include:

• Grass and plant pollens

• House dust mites

• Mould spores

• Other airborne allergens

  
  

When a dog with allergies comes into contact with these substances, their immune system reacts excessively, leading to itchy and inflamed skin.

Unlike flea allergies, environmental allergies often occur year-round or seasonally depending on the allergen.

Signs of Dog Skin Allergies - Itch skin

The most common symptom of atopic dermatitis is persistent itching.

Dogs with allergies may:

• Scratch constantly

• Chew or lick their paws

• Rub their face on the carpet or furniture

• Bite at their skin

• Shake their head or develop ear infections

  
  

Common areas affected include:

• paws

• ears

• face

• armpits

• belly

Because the skin becomes irritated, dogs can also develop secondary bacterial or yeast infections, which make the itching even worse. Some dogs with allergies also develop recurring ear infections or anal gland problems.

Dog Breeds More Prone to Atopic Dermatitis

Although any dog can develop allergies, some breeds appear to be more predisposed.

These include:

• Golden Retrievers

• Labrador Retrievers

• West Highland White Terriers

• Bulldogs

• Other terrier breeds

  
  

Mixed breed dogs can also develop atopic dermatitis.

How Veterinarians Diagnose Dog Allergies?

If your dog has ongoing itching, your veterinarian will first rule out other causes such as:

• fleas

• mites

• skin infections

  
  

Once other causes are excluded, allergy testing may be recommended.

Two main types of tests are used.

1. Intradermal Allergy Testing - Small amounts of allergens are injected into the skin and the veterinarian observes whether a reaction occurs.

2. Blood Allergy Testing - A blood sample is collected and sent to a laboratory to measure antibodies against environmental allergens.

Allergy testing helps identify the substances that trigger your dog’s symptoms

Treatment for Atopic Dermatitis in Dogs

Atopic dermatitis cannot usually be cured completely, but it can often be managed successfully.

Treatment plans usually involve a combination of strategies

1. Reducing Allergen Exposure. Although it is difficult to remove all allergens from a dog’s environment, some steps can help:

   1. regular bathing to remove allergens from the skin. Bathing can be especially helpful during high pollen seasons.

   2. medicated or hypoallergenic shampoos

   3. moisturising sprays or rinses

      
      

2. Anti-Allergy Medications

   Several medications may be used to control itching and inflammation.

   These may include:

   1. antihistamines

   2. corticosteroids

   3. cyclosporine

   4. Apoquel

   5. Cytopoint

      
      

3. Allergy Immunotherapy

   Some dogs benefit from allergy immunotherapy, commonly called allergy shots. This treatment gradually exposes the dog to small amounts of the allergens they react to. Over time, the immune system becomes less sensitive.

   
   

   Approximately 60–80% of dogs improve with immunotherapy, although it may take several months before improvement is seen.

Long-Term Management of Dog Allergies

Most dogs with atopic dermatitis require long-term management.

This may include:

• regular bathing

• allergy medications

• controlling secondary infections

• seasonal treatment during allergy flare-ups

With the right management plan, many dogs with allergies can live comfortable, active lives.
