The Root Causes of Dog Itching

Dec 09,2024 | puaintapets

A dog's itching can be a sign of various underlying issues that range from external factors to internal imbalances. Itching is not just an annoyance for the dog but can also be a cause for concern for the pet owner. External factors play a significant role. Parasites are a prime example. Fleas, those tiny yet pesky insects, can infest a dog's fur and skin, causing intense itching as they move around and bite. Simple factors like dry skin can be a cause. This can be due to over - bathing with harsh shampoos that strip the skin of its natural oils, or a diet lacking in essential fatty acids that are necessary for maintaining healthy skin. Understanding these causes is the first step in helping a dog with an itching problem.

What Are the Causes of a Dog’s Itching?

Itching, also known as pruritus, is one of the most common reasons pet owners visit the vet. While occasional scratching is normal, persistent itching can indicate an underlying issue. This guide explains the common causes of itching in dogs and how to address them.

1. Allergies

Allergies are a common cause of itching in dogs.

  • Food Allergies: Certain ingredients in a dog's diet can trigger an allergic reaction. Common culprits include beef, dairy, wheat, and chicken. For example, a dog may develop itchy skin, redness, and rashes after consuming a food containing a particular protein it is allergic to.
  • Environmental Allergies: Dogs can be allergic to pollen, dust mites, mold, or grass, leading to seasonal or year-round itching. Symptoms may include scratching, licking, and redness, especially around the paws, face, and belly.
  • Flea Allergy Dermatitis: Even a single flea bite can cause a severe allergic reaction in some dogs. The saliva of the flea is what usually triggers the immune system response, leading to intense itching, especially around the base of the tail, groin, and belly.

2. Parasites

Parasites can also make a dog itchy.

  • Fleas: Fleas are small, wingless insects that live on the dog's skin and fur. They move quickly and can be difficult to spot, but their presence is often indicated by excessive scratching, especially on the back, neck, and tail areas.
  • Ticks: Ticks attach themselves to the dog's skin and feed on its blood. In addition to causing itching, ticks can transmit diseases. The itching may be localized around the area where the tick is attached.
  • Mites: There are different types of mites that can affect dogs. For example, Demodex mites live in the hair follicles and sebaceous glands, while Sarcoptes mites burrow into the skin. Mite infestations can lead to intense itching, hair loss, and skin lesions.

3. Skin Infections

  • Bacterial Infections: Bacteria can infect the skin, especially if there are cuts, abrasions, or other skin irritations. Staphylococcus bacteria are a common cause of skin infections in dogs. The infected area may become red, swollen, and itchy.
  • Fungal Infections: Fungal infections like ringworm can also cause itching. Ringworm is highly contagious and can spread to other animals or even humans. It typically presents as circular, scaly patches on the skin.

4. Hormonal Imbalances

  • Hypothyroidism: This occurs when the thyroid gland does not produce enough thyroid hormone. One of the symptoms can be dry, itchy skin. The skin may also become thick and scaly.
  • Cushing's Disease: In this condition, there is an overproduction of cortisol in the body. It can lead to thinning of the skin, hair loss, and itching.

5. Hormonal Imbalances

Conditions like hypothyroidism or Cushing’s disease can disrupt the skin’s health, leading to itching, hair loss, or skin infections.

6. Behavioral Issues

Anxiety or boredom may cause your dog to lick or scratch excessively, even in the absence of a physical problem.

In conclusion, if your dog is experiencing itching, it is important to identify the underlying cause. A visit to the veterinarian is often necessary for a proper diagnosis and treatment plan. Early detection and treatment can help relieve your dog's discomfort and improve its quality of life.

How to Relieve Itching in Dogs?

1. Parasitic infection

If your dog's itching is caused by parasites (e.g. fleas, mites), it can be treated with appropriate  deworming medication.  

2. Bacterial or fungal infections

Itchy skin caused by bacterial or fungal infections is usually treated with antibiotics or antifungal medications. These medications can be taken orally or as topical ointments or sprays. 

3. Allergic dermatitis

If your dog's itching is caused by allergies, antihistamines or steroids can be used to reduce inflammation and itching. Also, allergens need to be identified and avoided.

4. Dry skin

If your dog's dry skin is causing the itching, moisturizers or specific skin care products can be used to improve the skin condition.

5. Anti-itch medications

In some cases, anti-itch medications can be used to relieve your dog's itchiness. For example, Epocrine (Olatinib maleate tablets) is a hormone-free anti-itch medication that can effectively control itching in about 4 hours. 

6. Medicated baths

Medicinal baths can help relieve itchy skin in dogs, especially for generalized skin problems. Using a medicated bath can help reduce inflammation and kill parasites. 

7. Environmental Improvement

Keeping your dog's living environment clean and regularly disinfecting and washing your dog's supplies can help prevent and treat itchy skin.

8. Diet adjustment

Choosing a dog food that is healthy for your dog's skin or adding some skin-friendly nutritional supplements, such as fatty acids and vitamins, can help improve skin conditions. 

When treating itchy skin in dogs, it is recommended to consult your veterinarian to determine the exact cause of the itching before choosing the appropriate treatment. At the same time, it is important to avoid using medications that contain hormones, which can adversely affect your dog's health. 

How to Prevent Itching in Dogs?

In order to prevent dog itching, you can start from the following aspects.

  • Regular deworming

Do external deworming on time to prevent parasitic infections such as fleas and mites, as parasites are one of the common causes of itchy skin in dogs. 

  • Keep skin clean

Bathe on time and use dog-specific body shampoo. Avoid using human bathing products as their pH level may not be suitable for dog's skin and may easily lead to skin problems. Dry thoroughly after bathing, especially in the skin folds, to prevent moisture from triggering skin diseases. 

  • Maintain balanced nutrition

Make sure there are no allergens in your dog's diet and choose a diet plan that is suitable for your dog to avoid food allergies. For dogs with allergies, consult your veterinarian for a special diet plan. 

  • Environmental cleanliness

Keep your dog's living environment hygienic, regularly wash and dry your dog's household items, such as kennels and toys, to reduce the growth of dust mites, mold and other allergens. 

  • Avoid contact with allergens

If your dog is allergic to certain substances, such as pollen and dust mites, try to minimize your dog's exposure to these allergens. For example, spend less time outside during pollen season and keep the house clean to minimize dust mites. 

  • Use air purifiers and humidifiers

Especially in environments with dry or polluted air, air purifiers can help remove allergens and irritants from the air, and humidifiers can keep the air humid and prevent dry skin. 

  • Supplement Omega fatty acids

Omega fatty acids help improve your dog's skin and coat health and can be supplemented by feeding fish oil or supplements containing Omega fatty acids. 

  • Regular Grooming

Brushing the coat removes dead skin and hair and encourages new hair growth, as well as removing allergens from the skin and coat.

When to Consult a Veterinarian

If your dog’s itching is persistent, intense, or accompanied by other symptoms like redness, swelling, or hair loss, consult your vet. They may perform tests to identify the cause and recommend a tailored treatment plan.
