If your dog has been scratching, biting, or licking their skin more than usual, you’re not alone. Itchy skin is one of the most common issues dog owners face — and it can drive both you and your pup crazy.
The good news? Once you know the cause, you can usually find a solution that brings quick relief.
In this guide, we’ll look at the most common reasons dogs scratch, and the best products and remedies to help.
Common Causes of Dog Scratching
Fleas & Ticks
Even one flea bite can make a dog itch like mad. If you see black specks (flea dirt) or notice your dog chewing their tail, fleas might be the culprit.
Allergies (Food or Environmental)
Dogs can be allergic to pollen, grass, dust mites — or even their food. Itching around the paws, ears, and belly often signals allergies.
Dry Skin
Low humidity, harsh shampoos, or poor diet can leave your dog’s skin flaky and itchy.
Skin Infections
Constant scratching can lead to bacterial or yeast infections, making the problem worse.
Parasites Beyond Fleas
Mites (mange) and lice are less common but can cause severe itching.
Best Solutions for Itchy Dogs
Here are vet-recommended ways to help your dog stop scratching — with product suggestions that you can easily find online.
1. Flea & Tick Control
Fleas and ticks are one of the most common reasons dogs scratch nonstop. Even a single flea bite can make their skin itch like crazy. The good news is that with regular flea and tick prevention, you can stop the itching before it starts. A good prevention routine also protects against skin infections, allergies, and other secondary issues that parasites can cause.

2. Anti-Itch Shampoos
A gentle, medicated, or oatmeal-based shampoo can provide instant relief for dogs with itchy skin. These shampoos soothe inflammation, wash away allergens, and restore moisture to dry, irritated skin. Bathing your dog regularly (but not too often) helps keep their coat healthy and prevents buildup of dust, pollen, or flea dirt that can trigger scratching.
Recommended Options:
Earthbath Oatmeal & Aloe Shampoo — A natural, soap-free shampoo that calms dry and sensitive skin. Perfect for dogs that need gentle care.
Vet’s Best Itch Relief Dog Shampoo — Contains tea tree oil and oatmeal to relieve itching, while cleaning and deodorizing the coat.

3. Skin & Coat Supplements
Sometimes the cause of itchy skin starts from the inside. Omega-3 fatty acids and other skin-healthy supplements help moisturize the skin and support a shiny, healthy coat. These are especially useful if your dog’s itching is due to dry skin, allergies, or seasonal changes. Regular use can noticeably reduce flakiness and scratching.
Recommended Options:
Zesty Paws Salmon Oil — A high-quality omega-3 supplement made from wild Alaskan salmon. Supports skin hydration and reduces inflammation.
PAW Dermega Skin Support Oil — An Australian favorite that nourishes the skin and coat with essential fatty acids.

4. Calming Relief for Allergies
Seasonal or environmental allergies are a huge culprit behind chronic itching. If your dog gets itchy paws, belly rashes, or ear problems during certain times of the year, allergy support can help. Mild cases often respond well to over-the-counter allergy chews or antihistamines, but persistent symptoms should always be discussed with a vet.
Recommended Options:
NaturVet Aller-911 Allergy Aid — Tasty soft chews that support the immune system and help reduce allergy-related itching. A good first step for mild seasonal allergies.

5. Keep Your Home Clean
Sometimes the problem isn’t your dog — it’s their environment. Allergens, flea eggs, and dust can accumulate in your home, especially in bedding, carpets, and furniture. A regular cleaning routine removes these triggers and creates a healthier space for your dog. This is especially important if your pup has allergies or sensitive skin.
Recommended Options:

High-Quality Vacuum Cleaner — A strong vacuum designed to pick up pet hair, dander, and microscopic allergens from carpets and couches.
