5 Home Remedies for Your Dog’s Itchy Skin

Some cases of itchy skin in dogs can be managed at home with supportive care, but the right treatment depends on the underlying cause.

Home remedies such as flea prevention, fish oil, medicated shampoos, topical skin products, and proper nutrition may help relieve mild itching or support skin health.

If your dog’s itching is severe or accompanied by skin changes, veterinary care is important because infections, allergies, or parasites may require prescription treatment.

1. Keep Flea and Tick Prevention Up to Date

Keeping your dog on year-round flea and tick prevention is one of the most effective ways to help prevent itchy skin caused by parasites.

Parasites are one of the most common reasons dogs develop itchy skin. Fleas are especially problematic because many dogs are allergic to flea saliva and can develop significant itching after just a single bite.

If your dog has itchy skin, the first step is to make sure they—and all other pets in the household—are current on their flea and tick prevention.

Regular grooming alone is not enough to prevent fleas or mites, as these parasites readily infest clean, healthy coats.

Several types of flea and tick preventatives are available. For example:

• Topical products such as Advantix II™ and Seresto® collars may help repel fleas, which can be especially beneficial for dogs with flea allergies.
• Long-acting oral preventatives such as Bravecto® help maintain continuous protection throughout the flea life cycle.
• Bravecto® and other isoxazoline products also treat certain mite infestations, including demodectic and sarcoptic mange.

Because every dog has different health needs and risk factors, ask your veterinarian which flea and tick prevention is most appropriate for your pet.

2. Add Omega-3 Fish Oil (When Recommended)

Omega-3 fish oil supplements may help improve skin health and reduce inflammation in some dogs with itchy skin.

Fish oil is an excellent source of omega-3 fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which have been shown to support skin health and reduce inflammation in certain canine skin conditions.

While most commercial dog foods already contain omega-6 fatty acids such as linoleic acid and arachidonic acid, they are not required to contain omega-3 fatty acids like EPA and DHA.

Many veterinarians recommend fish oil products made from anchovies or sardines, as these are generally considered high-quality and more sustainable sources than farmed salmon.

If your dog doesn't tolerate capsules well, many fish oil products are also available in liquid formulations that can be mixed directly into food.

Fish oil should be used carefully, especially in dogs with sensitive stomachs or when higher doses are given, as gastrointestinal upset and pancreatitis can occur.

Before starting any supplement, talk with your veterinarian to determine the appropriate product and dosage for your dog.

3. Bathe With Oatmeal or Medicated Shampoo

Oatmeal shampoos formulated for dogs may help soothe itchy skin, support the skin barrier, and reduce irritation.

Colloidal oatmeal has antioxidant and anti-inflammatory properties that may help moisturize the skin, strengthen the skin barrier, and provide additional protective benefits when applied topically. It may also offer mild antifungal and UV-protective effects.

Colloidal oatmeal is produced by finely grinding oats and processing them to concentrate these beneficial compounds, making it a popular home remedy for mild itchy skin in dogs.

For the best results, choose shampoos specifically formulated for dogs. Human shampoos—even those containing oatmeal—can disrupt your dog's skin barrier and may worsen irritation.

If your dog's itching is more severe or caused by an underlying skin condition, your veterinarian may recommend a medicated shampoo as part of their treatment plan.

4. Use Veterinary-Recommended Topical Products

Topical skin-care products can help support dogs with itchy skin, especially when frequent bathing isn't practical.

Mousses, spot-on products, and topical sprays can help maintain the skin barrier and provide targeted relief for irritated areas without requiring frequent baths.

Depending on your dog's needs, your veterinarian may recommend products such as:

• Moisturizing mousses to support the skin barrier and treat the entire body or localized areas like the armpits and lower belly.
• Spot-on therapies, such as Dermoscent®, to moisturize dry, flaky skin and help support the skin's natural defenses against bacterial infections.
• Topical sprays, such as Vetericyn® Plus, to help soothe hot spots and irritated skin while your dog recovers alongside any medications prescribed by your veterinarian.

Topical products often work best as part of a broader treatment plan, so talk with your veterinarian about which option is most appropriate for your dog's specific skin condition.

5. Feed a Skin-Supportive Diet

A balanced diet plays an important role in maintaining healthy skin and may help support dogs with itchy skin.

Choose a dog food that is complete and balanced and meets the nutritional standards established by the Association of American Feed Control Officials (AAFCO). Nutritional deficiencies can contribute to poor skin and coat health.

If your dog is already eating a balanced diet but still experiences itchy skin, your veterinarian may recommend switching to a formula designed for sensitive skin and sensitive stomachs.

These diets often contain increased levels of omega-3 fatty acids and antioxidants that support skin health.

In some dogs, persistent itching may be related to a food allergy. The most common food allergies involve animal proteins such as:

• Chicken
• Beef
• Pork

If a food allergy is suspected, your veterinarian may recommend trying a limited-ingredient diet or a diet made with a novel protein your dog has not eaten before.

In some cases, a prescription elimination diet may be necessary to properly diagnose and manage food allergies. Your veterinarian can help determine the most appropriate nutritional plan for your dog.

When Should You See a Vet for an Itchy Dog?

Home remedies may help mild itching, but dogs with severe or worsening skin problems should be examined by a veterinarian.

If your dog's skin becomes red, scabby, painful, develops an odor, or appears infected, schedule a veterinary appointment as soon as possible.

These signs may indicate a bacterial or yeast infection that requires prescription treatment, such as antibiotics or antifungal medications.

Contact your veterinarian promptly if your dog has:

• Red or inflamed skin
• Scabs or sores
• A foul or unusual skin odor
• Painful skin
• Persistent or severe itching

Dogs with significant itching may also require prescription medications to reduce inflammation and allow the skin to heal.

Depending on the underlying cause, your veterinarian may prescribe treatments such as Apoquel®, Cytopoint®, corticosteroids, antibiotics, or antifungal medications.

The sooner the underlying cause of your dog's itching is identified, the sooner they can begin receiving the most effective treatment and find relief.
