The Bottom Line

Of all allergy and immunity supplements for dogs that we tested on the market, PetScy's Vet-Recommended Itch Relief Chews are the clear winner. It has a robust formula which can effectively protect your dog’s skin & coat from infections, irritation and prevent itching.

When compared to other brands on the market, PetScy's Vet-Recommended Itch Relief Chews  are one of the few products which had a complete formula which provides benefits for immunity, seasonal allergies and in reducing their accompanying symptoms.

Itch Relief Chews also includes other beneficial ingredients such as Vitamin C, E, Biotin, and Zinc It is truly a complete formula that targets all aspects of their immune system and reduces inflammation.

Our favorite aspect of this product is that it comes in a tasty flavored chew, which makes it easy to administer just like a treat for your dog.

Itch Relief Chews is Made in the USA and comes with a 30 Day Hassle-Free Guarantee + Free Shipping. This helps ensure the safety and accuracy of their ingredients and allows owners to try them risk free. Overall, we rank PetScy's Vet-Recommended Itch Relief Chews as the best product on the market in 2024.

The Bottom Line

These Probiotic Health Chews are a similarly high quality product, with stellar benefits for your dog.

Made with 8 strains of beneficial bacteria, this product can help relieve your dog’s allergies while preventing infection due to overgrowth of dangerous bacteria. This makes it a great complementary product to the Allergy chews from the same company or as a standalone product to boost your dog’s digestive health.

The highlight of this product is that it contains much stronger Probiotics than others on the market. It can therefore target certain causes of Allergy problems such as imbalance in gut bacteria and poor digestion.

Overall, we would recommend Probiotic Health Chews alongside their Itch Relief Chews if your dog needs some extra help in subduing those pesky allergies..

The Bottom Line

Zesty Paws is a well-known supplement on the market. It is a high quality formula, however, it does fall short on a couple of points.

Firstly, it has too low of a dose of Probiotics at just 250 Million CFU. We normally recommend at least 1 Billion CFU for effectiveness. In addition, it fails to include any prebiotic which is crucial for the Probiotics to have an impact.

In addition, it does not contain Quercetin or Turmeric, which is important to reduce inflammation and get to work on reducing sores, infections or irritations.

Lastly, as a generic formula which caters to both cats and dogs, there may be some lost effectiveness as both types of pets do have different nutritional needs. We recommend sticking to a supplement which is focused purely for dogs when it comes to something as important as their immune system.

The Bottom Line

Naturvet is a trusted brand, however, their allergy product does fall short on a few factors.

Firstly, it contains no Colostrum or Probiotics, two powerhouse ingredients which we believe to be essential in immune health and fighting allergies. In addition, it fails to include complimentary ingredients such as Apple Cider Vinegar or Apple Pectin.

Most importantly however, it includes Maltodextrin in their inactive ingredients, which while deemed safe generally speaking, may increase harmful bacteria in their gut. Finally, they do not appear to offer a clearly defined money back guarantee.

The Bottom Line

Chew + Heal is a relatively new brand and their allergy product is called Allergy Aid. Their formula is quite basic but reasonably priced.

They fail to include powerhouse ingredients such as Colostrum or Probiotics but they have included less effective ingredients such as Bromelain.

This formula would be recommended if you are on a budget, however its effectiveness may be dubious given the lack of essential ingredients.

Finally, we did not find any clearly defined Money Back Guarantee, which makes it higher risk to try if there is no improvement.
