There are natural oral options that work and won't leave your canine companion giving you the side-eye.

 

From essential fatty acids to gut-friendly goodies, you have choices that are safe and easy to sneak into dinner. Keep reading, and we'll explain it all in a way that makes sense for real-life dog parents like you.

 

 

Natural Oral Remedies for Itchy Dog Skin

 

Natural oral remedies help manage your dog's itchy skin by supporting their body from within. For example, options like omega-3 fatty acids and probiotics may help reduce skin irritation without relying on heavy meds.

 

These solutions can target common causes of itchy skin, including food allergies, flea allergies, fungal infections, seasonal changes, and skin diseases. You can add them to your dog's food or offer them as chewable treats. Many work by strengthening the skin, calming upset stomachs, or balancing immune responses that cause flare-ups. In the next sections, let's talk about these common natural remedies:

 

• Omega-3s To Soothe and Support Skin

• CBD for Calming and Comfort

• Quercetin for Allergic Dogs

• Probiotics for Gut-Skin Balance

• Herbs and Antioxidants for Skin Support

 

Omega-3 Fatty Acids (Fish Oil, Flaxseed Oil)

Omega-3 fatty acids support the skin barrier and may reduce puffiness and redness caused by skin allergies and food sensitivities. Fish and flaxseed oils are two easy ways to add omega-3s to your dog's diet. You can find them in liquid form, capsules, and treats.

 

These oils work by helping the skin hold moisture, which can then help reduce dry, flaky skin. They also support a balanced immune response, which is useful for pups dealing with seasonal allergies or environmental triggers.

 

Most pet owners start with fish oil because it's rich in EPA and DHA. Flaxseed oil is a good plant-based alternative. Always check with your vet before adjusting your dog's diet.

 

CBD for Dogs With Skin Irritation

 

CBD (cannabidiol) is another natural option many dog parents turn to for skin troubles. It may help calm irritated skin and support a more relaxed, balanced response to allergy symptoms without the heavy sedation.

 

HolistaPet's CBD Collection for Dogs includes oils, soft chews, and crunchy treats made with broad-spectrum CBD, meaning no mind-altering THC (tetrahydrocannabinol). Our products may help soothe discomfort, support healing, and help your pet stay calm during flare-ups. They're especially useful if your dog's itching gets worse during stressful situations like vet visits or thunderstorms.

 

Many pet parents use CBD daily to support skin health and keep scratching in check. It's easy to mix into food or give on its own. Start with a low dose and adjust as needed. Of course, consult your vet about it first.

 

Quercetin – Nature's Benadryl for Dogs

Quercetin is a plant-based compound that acts like a natural allergy medicine for dogs. It helps calm allergic reactions by supporting the immune system and easing itchy skin.

 

You'll often find quercetin in chewables or powdered products made for dogs. Some formulas combine it with bromelain, which helps the body absorb it better. It works best when given consistently and may be especially helpful for pets with environmental allergies or food triggers.

 

Always check the label to make sure it's safe for pets. Human versions sometimes include ingredients dogs shouldn't have. With your vet's approval, start with a small amount, and watch how your buddy responds.

 

Probiotics and Gut Health Support

Probiotics help balance your dog's gut, which can positively affect skin health. A lot of itchy skin problems actually start with upset stomachs, poor digestion, and food sensitivities. When your pup's gut is off, you'll notice that their skin often reacts.

 

Adding probiotics can support the gut microbiome, improve nutrient absorption, and calm the body's reaction to common allergens. Good news: HolistaPet's probiotic formula for dogs may support digestion, immune function, and skin comfort all in one daily chew.

 

Use probiotics every day for the best results (confirm with your vet first, of course). You might start to notice fewer flare-ups, better stool consistency, and less paw licking. Just be consistent and patient because gut health takes time to show on the outside.

Herbal Supplements and Antioxidants

Herbal supplements and antioxidants can help reduce skin irritation by calming the body's natural response to allergens. Ingredients like nettle leaf, licorice root, and turmeric are popular picks. These herbs may ease agitation and support overall skin comfort when added to your dog's routine.

 

Antioxidants like vitamin E and vitamin C also play a key role. They help protect skin cells and support the immune system, especially during allergy season. If your dog struggles with environmental allergies or dry, flaky, and itchy skin, these remedies can be a gentle option to consider.

 

You'll find many of these ingredients in soft chews or powder blends. Choose vet-approved, pet-safe products with clear dosing instructions. If your dog has sensitive skin or frequent flare-ups, this type of support may offer some daily relief.

 

 

Why Is My Dog So Itchy?

Some dogs react to pollen or dust. Others have sensitive stomachs that show up as skin problems. Itchy skin can also come from yeast or bacterial skin infections, especially if your pup licks or chews the same spots over and over. Even dry weather can mess with their skin barrier.

 

Start by watching when the itching flares up. Is it seasonal? After meals? After walks? The timing gives you clues.

 

Common Causes of Itchy Skin in Dogs

A little scratching here and there is normal, but constant licking, biting, or scooting is usually a sign that something's off. Here are the most common triggers behind your dog's itchy skin:

 

• Flea Allergy Dermatitis. One bite can lead to days of itching if your pup reacts to flea saliva.

• Environmental Allergies. Dust, pollen, grass, and mold can cause allergic reactions that affect your dog's skin.

• Food Allergies. Certain ingredients—like chicken, dairy, or grains—can lead to skin irritation and an upset stomach.

• Yeast or Bacterial Infections. Overgrowth of natural bacteria or yeast can lead to red, irritated skin, often with odor.

• Dry Skin. Low humidity, frequent baths, or harsh shampoos can strip natural oils and leave skin flaky.

 

Signs It's Time To Treat the Itching Internally

If the itching starts to mess with your pet's comfort, appetite, or mood, it may be time to treat it from the inside. Topical treatments and shampoos help in the short term, but internal support can target the root of the problem. Watch for these signs:

 

• Constant Licking or Chewing. Especially on paws, legs, or belly. This often means the skin feels irritated or itchy.

• Red or Inflamed Skin. Redness, puffiness, or visible discomfort could signal an allergic reaction.

• Hair Loss or Bald Spots. Scratching too much can lead to patches of missing fur or thinning coats.

• Frequent Ear Infections. Recurrent ear trouble can link to allergies, especially food-related ones.

• Unpleasant Odor or Greasy Skin. These may point to yeast or bacterial infections, both common in allergic dogs.

 

 

Vet-Approved Oral Medications for Dog Itching

 

If natural remedies aren't cutting it, vet-approved oral meds might be the next step. These medications help control allergy symptoms and give your dog real relief, especially if the itching is nonstop or getting worse.

 

Some meds work by calming your pet's immune response. Others block the itch signals directly. Your vet may recommend allergy medications, oral steroids, or newer drugs designed specifically for allergic dogs. Many of these start working fast, typically used for both short-term flare-ups and long-term plans.

 

Always follow your vet's instructions closely. Dosage, timing, and possible side effects vary depending on the medication. And if you're unsure, ask about combining meds with natural support like fish oils and probiotics for better skin health overall.

 

Over-The-Counter Antihistamines (Benadryl, Claritin)

Some over-the-counter antihistamines may help ease mild allergy symptoms in dogs. Options like Benadryl (diphenhydramine) or Claritin (loratadine) are often used to calm itching caused by seasonal allergies or mild food reactions. But dosing for dogs isn't the same as for people, so always check with your vet first.

 

These meds work by blocking histamines, which are chemicals the body releases during allergic reactions. If your dog's itching flares up during certain times of the year, antihistamines might help reduce scratching, licking, and even ear irritation.

 

Stick to plain versions with no added ingredients like decongestants. And monitor your pooch after giving a dose, as some dogs get drowsy, while others may not respond at all. It's a helpful option, but not a cure-all. Always use with caution and under veterinary guidance.

 

Prescription Medications and What To Know

For more severe allergies, your vet may suggest prescription meds. These are stronger than over-the-counter options and often work faster to help ease your pup's constant itching. Common choices include Apoquel, Cytopoint, and low-dose steroids.

 

Each medication works differently. Some target the immune system, while others block itch signals in the body. These can be helpful for dogs with atopic dermatitis, flea allergies, or year-round allergy symptoms that don't respond to natural options.

 

Talk to your vet about side effects and long-term use. Some prescriptions are for short-term relief only, while others are fine for daily use. Often, combining these with natural support can give even better results, so chat with your vet about it.

Probiotics for Gut Health

 

HolistaPet's Probiotic Soft Chews may also help calm skin issues caused by food allergies or immune flare-ups. Remember, a healthy gut supports a steady immune system, which plays a big role in responding to and managing allergies and irritation.

 

These chews feature ProbioSeb Multi™, a powerful blend of nine live strains (including L. acidophilus, L. rhamnosus, and Bifidobacterium bifidum) delivering 3 billion CFU per dose. This mix helps improve digestion, support nutrient absorption, and may reduce flare-ups linked to an unbalanced gut.

 

They're a great daily option for dogs with sensitive skin or upset stomachs. One chew a day helps to keep things balanced inside, so you see fewer signs of itching or discomfort on the outside.

HolistaPet's Multivitamin Soft Chews offer full-body support with extra love for the skin. These daily chews pack skin-friendly nutrients like vitamin E, vitamin C, and biotin. These are key players when it comes to supporting the skin barrier and calming dryness or irritation.

 

They're also great for pets dealing with food allergies, sensitive skin, or seasonal flare-ups. Each chew includes a blend of vitamins and minerals that support immune health, coat quality, and nutrient absorption. That's a solid base for managing skin issues from the inside.

 

Give one daily based on your dog's weight. It's an easy addition to their routine and helps maintain healthy skin while covering other wellness needs at the same time.

 

Skin, Coat, and Nail Soft Chews

HolistaPet’s Skin, Coat, and Nail Soft Chews help your canine companion look and feel their best, especially if itchy skin keeps coming back. These chews support the skin barrier with ingredients like fish oil, aloe vera, ascorbic acid, and biotin, which may help with dryness, flakiness, and redness.

 

They're a solid choice for pups dealing with seasonal allergies, food reactions, or year-round irritation. The formula also promotes stronger nails and a shinier coat, which often go hand in hand with better skin health.

 

Use them daily as part of your pet's routine. Over time, you may notice less scratching, fewer hot spots, and a healthier coat. 

 

 

External Options To Support Oral Remedies

Sometimes, your dog needs extra help on the outside, too, like soothing shampoos, gentle sprays, and smart grooming habits. Together, they help calm irritated skin while the internal stuff does its job. Here's what we'll talk about next: 

 

• Hypoallergenic and Medicated Shampoos To Clean Without Causing Irritation

• Topical Balms and Soaks for Quick Skin Relief

• Smart Grooming Habits To Keep Allergens Off and Skin Calm

 

Hypoallergenic and Medicated Dog Shampoos

 

Hypoallergenic and medicated shampoos can help clean the skin gently without drying it out or making things worse. Look for formulas made specifically for dogs.

 

HolistaPet's CBD Dog Shampoo includes broad-spectrum CBD to help keep the skin calm and moisturized. It's a good choice if your pooch deals with redness or tends to scratch after baths. It's free from harsh chemicals that can trigger more itching.

 

Use lukewarm water, rinse thoroughly, and avoid overbathing, as too many baths can strip natural oils. Once a week or every other week is usually enough for most dogs with skin issues. Always dry completely to avoid yeast buildup.

 

Topical Balms, Sprays, and Oatmeal Soaks

Balms, sprays, and soaks help soothe problem spots while your dog's oral remedies work behind the scenes. They're especially helpful for paws, bellies, and other areas that get red or inflamed during allergy season.

 

Oatmeal soaks are gentle and easy to make at home. Just add plain, ground oats to lukewarm bathwater and let your dog soak for 10–15 minutes. It can help calm dry, flaky skin. Always rinse thoroughly and pat dry carefully.

 

For smaller flare-ups, try dog-safe sprays or balms with ingredients like aloe, coconut oil, or hemp. Use on hot spots and between toes. These can help protect the skin barrier and lock in moisture.

 

Grooming, Bathing Frequency & Allergen Reduction

Regular brushing helps remove dirt, loose hair, and allergens that stick to the coat. This can reduce flare-ups from things like pollen, dust, or grass, especially for dogs with environmental allergies.

 

Bathing too often can dry out the skin, but not bathing enough can allow buildup and cause irritation. Aim for once every 2 to 4 weeks with a gentle, dog-safe shampoo. If your pet's outside a lot or rolls in the yard, you might need to rinse their paws or belly more often between full baths.

 

Keep bedding clean, vacuum weekly, and use air filters indoors if possible. Small changes in your cleaning routine can go a long way in reducing triggers that lead to itchy skin.

 

 

FAQs About Oral Remedies for Itchy Skin in Dogs

A lot of dog owners want to help their pups but aren't sure what's safe, what works, and how long it takes to see results. In the next few sections, we'll cover the most common questions pet parents ask about managing their dog's itchy skin, from daily options to what to try if you're out of Benadryl. Let's get into it.

 

What is the best supplement for itchy dogs?

There's no one-size-fits-all solution, but many dog owners see great results with omega-3 fatty acids, probiotics, and CBD. These natural options work from the inside to help support the skin, calm immune responses, and ease agitation tied to allergies or food triggers.

 

Fish oil is a top pick, as it helps support the skin barrier and may reduce dry, flaky skin. Probiotics balance the gut and immune system, which can cut down on skin flare-ups caused by food sensitivities. And CBD may help soothe discomfort and promote healthier skin overall.

 

Look for clean, dog-safe products with no fillers or artificial stuff. Start slow, follow the directions, and give it time. These options usually need a couple of weeks to show results.

 

Can I give my dog Benadryl every day?

Benadryl can help with mild allergy symptoms, but daily use isn't always the best long-term plan. It's safe for many dogs in small, vet-approved doses, but giving it every day could lead to drowsiness or reduced effectiveness over time. Always use plain Benadryl (no added cold meds or decongestants), and never guess the dose. Your vet can tell you how much is right.

 

If your pooch needs constant relief, talk to your vet first. They might suggest a different antihistamine, a prescription option, or combining Benadryl with other strategies like omega-3s or probiotics. 

 

How long do oral remedies take to work for itchy skin?

Most oral remedies don't work overnight, especially the natural ones. It often takes 1 to 3 weeks to see noticeable changes. That's because these remedies work gradually to support the skin, gut, and immune system.

 

Fish oils and probiotics, for example, need time to build up in your dog's system. You might notice less scratching, calmer skin, or softer fur by the second or third week. Prescription meds may act faster, but they're usually part of a bigger plan, not a standalone fix.

 

Stay consistent. Skipping doses or switching products too soon can slow progress. If nothing improves after a month, it's time to check in with your vet for next steps.

 

Are there side effects with natural supplements for dogs?

Most natural supplements are well-tolerated, but side effects can happen, especially if the dose is too high or your dog has sensitivities. Mild stomach troubles like gas or soft stool are the most common signs that something might not be sitting right.

 

Start with the lowest recommended dose and watch for any changes. If your dog seems off—less hungry, low energy, or has a change in bathroom habits—pause the intake and check with your vet. Sometimes, it's just a matter of adjusting the dose or switching to a different product.

 

Stick with trusted brands that list ingredients clearly (like HolistaPet). Look for products made for dogs, not people. And always introduce one new solution at a time so you know what's working and what's not.

 

What can I give my dog for itching if I don't have Benadryl?

If you're out of Benadryl, natural remedies like fish oil, CBD, and quercetin are easy to give and often help calm itching from the inside. These are especially useful if your pup scratches due to food or seasonal allergies.

 

You can also try coconut oil or apple cider vinegar mixed into your dog's food in small amounts. These may support skin comfort and the immune system. Just be sure not to overdo it. Stick to small servings and see how your buddy reacts.

 

If the itching is intense or doesn't improve, reach out to your vet. They may suggest an alternative antihistamine, allergy meds, or supplements that better fit your dog's needs. It's always better to treat the cause, not just the scratching.
