7 Best Dog Allergy Supplements to Beat The Itch

Dog allergies are a common issue many pet owners face, causing symptoms like itching, redness, and discomfort in dogs. Supplements designed for dog allergies aim to support the immune system and improve skin health by addressing these symptoms internally. These products typically contain ingredients such as omega fatty acids, vitamins, and natural anti-inflammatories.

Choosing the right dog allergy supplement involves looking closely at ingredient quality and efficacy. It’s important to avoid fillers and allergens in the supplement itself, as well as to check for the right dosages that match the severity of your dog’s symptoms. Transparency in sourcing and manufacturing is also a key factor.

We evaluated multiple dog allergy supplements to find options that can reliably support dogs dealing with allergies and promote healthier skin and coat.

#1 – Native Pet Allergy Chews

These chews offer a natural approach that can noticeably reduce itching for many dogs, making them a solid choice if you want to avoid harsh chemicals.

Pros

• Natural ingredients reduce itching without fillers
• Supports immune health with probiotics and colostrum
• Dogs generally enjoy the chicken flavor

Cons

• Takes a couple of weeks to see full effects
• Can be pricey compared to other supplements
• Some dogs may still itch despite use

We found these chews to work steadily over time rather than providing immediate relief. Our dog gradually scratched less after a couple of weeks, which felt encouraging. The natural formulation and lack of artificial additives stood out to us.

The flavor was a clear win. Giving the chews didn’t turn into a struggle since our dog accepted them readily. This made daily administration easy, which is important for consistent use.

While the itch reduction was noticeable, it didn’t completely stop scratching in more severe cases. We’d recommend them as part of a longer-term allergy management plan rather than a quick fix.

#2 – PetLab Co. Allergy Probiotics

This supplement is a solid option for managing seasonal allergies and yeast issues in small dogs, though some pups may be picky about the chew size or flavor.

Pros

• Helps reduce itchiness and paw licking in many dogs
• Combines probiotics and omega oils for gut and skin support
• Made in the USA with carefully chosen ingredients

Cons

• Chew size may be too large for very small breeds
• Some dogs initially reject the flavor or texture
• Results can vary; not effective for all allergy types

We noticed a calming effect on itchiness after giving this to our dogs for a couple of weeks. The blend of probiotics and omega fatty acids seemed to support their gut and skin health without upsetting their stomachs.

The bonus is that it targets yeast overgrowth, which helped with paw licking and ear odors in some cases. However, it’s clear the product isn’t a quick fix—consistent daily use is necessary to see improvement.

While most of our small dogs accepted the pork-flavored chews easily, a few needed the pieces broken down or offered in a treat to get used to the taste. Overall, it’s a well-rounded supplement worth trying if your dog struggles with seasonal or yeast-related allergies.

#3 – iHeartDogs Allergy Relief Chews

If you want a supplement that targets itching and supports immune health, this is a reasonable option to consider.

Pros

• Noticeable reduction in itching after a few days
• Supports immune and digestive systems
• Easy to give as a bacon-flavored chew

Cons

• Some dogs need multiple chews daily
• Mixed results on long-term itch control
• A few dogs may reject the taste

We found these chews started easing our dog’s irritation quickly, which was a positive surprise. They do a good job addressing various allergy symptoms including paw chewing and redness. The bacon flavor made it simple to include in daily treats.

The immune support and probiotics are a big plus for dogs prone to allergies that flare seasonally or due to food. However, it’s clear that the product doesn’t work equally well for every dog over time, and some need three chews a day to maintain effects.

Overall, this supplement can be helpful for managing mild to moderate allergic reactions, but it might not fully eliminate intense itching in all cases.

#4 – Natural Dog Company Aller Immune Chews

These chews offer a strong formula for allergy relief but may not appeal to every dog’s taste or work quickly for all pets.

Pros

• Contains high doses of salmon oil, colostrum, and turmeric for multi-layered support
• Supports immune, skin, coat, and gut health simultaneously
• Vet trusted quality with NASC Preferred Seal

Cons

• Some dogs strongly dislike the smell and taste
• Results can take weeks to appear, not immediate
• Must manage dosage carefully by dog size

We noticed these chews give solid immune and skin support over time, especially for dogs with persistent itching. The mix of ingredients feels well thought out for overall allergy and gut health.

Taste was a challenge for us; our dogs were reluctant to eat them without hiding them in strong-flavored foods. This could make daily administration tough for picky eaters.

Patience matters with this one. It took several weeks before we saw meaningful changes, so it’s not a fast fix. Still, it delivered slow but steady relief once our dogs adapted to the chews.

#5 – Pawsential Allergy Relief Chews

This supplement is a solid choice for managing dog allergy symptoms with natural ingredients and gut health support.

Pros

• Noticeable reduction in itching within a week
• Small, easy-to-administer chew size for all breeds
• Supports skin, coat, immune, and gut health

Cons

• Some dogs may initially dislike the chicken flavor
• Results can vary depending on severity of allergies
• Contains chicken, which is a common allergen for some dogs

We found these chews helpful in calming our dog’s scratching and licking fairly quickly. The smaller bite size made it easy for our smaller breed to chew without any struggle.

The combination of omega fatty acids and probiotics seems to contribute not only to itch relief but also to a shinier coat and improved digestion. It felt like a comprehensive approach rather than just a quick fix.

However, a few dogs took some time to accept the flavor, so patience may be necessary when starting. Also, some allergy symptoms didn’t disappear entirely, indicating this may work best as part of a broader allergy management plan.

#6 – iHeartDogs Salmon Oil

This salmon oil supplement is a solid choice for supporting your dog’s skin and coat health while easing allergy symptoms.

Pros

• Rich in omega fatty acids that promote a healthy coat and reduce itching
• Easy to dose with the built-in pump dispenser
• Supports overall immune system, joint, and heart health

Cons

• Some dogs may not like the fishy taste
• Results on itching can be gradual, not immediate
• Larger bottle size may be too much for single small dogs

We’ve seen this product bring noticeable improvement in dogs with dry, itchy skin after consistent use. Adding it to meals is simple, and the pump makes measuring straightforward compared to messy oils.

The fish oil itself has a mild smell and taste, but a few dogs showed little initial interest, so we recommend trying a small serving first. Over weeks, coats looked softer and the scratching eased for most of our dogs.

This formula also feels good to support joints and heart health at the same time, making it a practical supplement to daily care. It’s especially useful if your dog suffers from seasonal allergies or flaky skin problems.

#7 – iHeartDogs Allergy & Itch Relief Balm

This balm offers natural, gentle relief for common dog skin allergies and dry, irritated spots.

Pros

• Easy, mess-free stick applicator
• Combines multiple soothing ingredients
• Nourishes and hydrates sensitive areas

Cons

• Small size runs out quickly
• Results vary depending on severity
• Dogs may lick it off immediately

The stick format made applying the balm straightforward without the residue mess we expected. Its blend, including Manuka honey and shea butter, genuinely calmed our dog’s hot spots and dry paws after a few days.

However, the product quantity is limited. We found the balm drained quickly with daily use on multiple spots, so frequent repurchasing may be necessary.

Some dogs might lick it off before it absorbs, reducing effectiveness. Applying when pets are calmer helps, but it’s not foolproof. Overall, this balm is worth trying for mild to moderate allergy irritation.
