What causes itching in dogs?

Itching in dogs can be caused by various factors. The most common causes are:

• Parasites: Fleas, mites and ticks cause skin irritation<1><3>.
• Allergies: Food allergies, environmental allergies (pollen, dust mites) or contact allergies (dog bed, cleaning products)<2><3>.
• Skin infections: Bacterial and fungal infections often occur following skin damage caused by scratching<3><5>.
• Dry skin: A deficiency in essential fatty acids can cause flaky, itchy skin<1>.
• Stress and behaviour: Dogs with separation anxiety or boredom may lick and scratch excessively<2>.

A veterinarian can determine the exact cause using skin scrapings, blood tests or allergy tests<3><5>.

How do you treat itching in dogs?

1. Medical treatments

Some conditions require a medical approach. Some effective treatments include:

• Parasite control: Flea treatments such as spot-on products (fipronil, selamectin), flea collars or medicated shampoos<1><3>.
• Treatment of infections: Antibiotics for bacterial infections, antifungal agents for skin infections<3><5>.
• Allergy treatment: Hypoallergenic diet (insect protein, grain-free), immunotherapy (desensitisation)<1><3>.
• Anti-itch treatments: Corticosteroids (in severe cases), antihistamines and cyclosporine reduce inflammation<1><3>.

2. Natural remedies for itching

Some home remedies can relieve mild itching and moisturise the skin:

• Coconut oil: Has antimicrobial properties and strengthens the skin<1><4>.
• Aloe vera gel: Relieves itching and soothes minor wounds<1><4>.
• Oatmeal baths: Soothes skin irritation and moisturises dry skin<4>.
• Chamomile tea: Apply lukewarm to the skin to reduce redness and itching<4>.
• Cottage cheese or yoghurt: Cools the skin and can reduce inflammation<1>.

3. Dietary changes for healthy skin

Nutrition plays a key role in managing itching. Consider:

• Hypoallergenic nutrition: Avoid grains; opt for insect proteins or fish-rich nutrition<1><2>.
• Essential fatty acids: Nutrition rich in omega-3 and omega-6 (salmon oil, linseed) supports skin repair<4><5>.
• Probiotics and vitamins: Vitamin E supplements and probiotic yoghurt help maintain healthy gut flora, which reduces allergies<4><5>.

What can you do to prevent itching?

Preventive measures help prevent recurring itching:

1. Regular coat care

A well-groomed coat prevents the build-up of allergens and parasites:

• Brushing: 2–3 times a week to remove loose hair and dirt<2><5>.
• Mild dog shampoos: Use a pH-neutral shampoo without fragrances<2>.
• Do not wash too often: No more than once a month to prevent dryness<2>.

2. Reducing stress

Some dogs scratch due to stress or boredom. Adjustments such as:

• More exercise: Long walks or playtime reduce stress and scratching behaviour<4>.
• Distractions: Chew toys, snuffle mats or brain teasers provide mental stimulation<1>.
• Calming supplements: Bach flower remedies or valerian for relaxation<2>.

3. Environmental control and allergy prevention

• Avoid dust mites and mould: Wash dog bedding at 60°C and vacuum regularly<3>.
• Hypoallergenic cleaning products: Use fragrance-free detergents for blankets and beds<3>.
• Avoid problematic food ingredients: Eliminate food allergens in consultation with a veterinarian<3>.

When should you visit a veterinarian?

Consult a veterinarian if:

Symptom	Possible cause	Action
Itching lasting longer than 2 weeks	Allergies, parasites	Examination required
Redness, bald patches, sores	Fungal or bacterial infection	Antibiotics or antifungal medication required
Excessive licking or biting of paws	Food allergy, stress	Dietary changes or behavioural adjustments
Blisters, pus or scabs	Serious infection or skin disease	Immediate medical treatment required

Persistent or worsening itching requires specialist diagnosis, such as a referral to a dermatologist<3><5>.

Conclusion

Dogs with itching may suffer from parasites, allergies, skin infections, nutritional deficiencies or stress. Treatments range from medication and natural remedies to dietary changes. Regular coat care, stress reduction and allergy prevention help to prevent recurring itching. Contact a veterinarian if the symptoms persist for longer than two weeks or if additional symptoms occur.
