Packed With High Quality Ingredients


A Proprietary Blend of Probiotics

This specific fusion of spore-forming probiotics can help maintain healthy canine gut flora, as well as support digestive and immune health.


Colostrum (Bovine)

Colostrum is a protein-rich fluid produced from mammary glands. This hugely beneficial ingredient can help support good gut microbes and healthy skin.

krill oil

Krill Oil (Omega 3, EPA, DHA)

Our Krill Oil features a mega source of omega-3 fatty acids, which directly help to support skin and coat health in dogs.


Prebiotics (FOS & GOS)

Prebiotics are just as important as probiotics! This powerful addition can help promote the growth of beneficial bacteria in the digestive system, and also acts as "food” for the probiotics. Together, FOS & GOS can also support your dog’s immune system, and help with occasional allergy discomfort.

borage oil

Borage Oil

Bursting with omega fatty acids, Borage oil can help to support skin and coat health.


Synergistic Yeast Postbiotic Blend

Lastly, we have postbiotics! Ours is a synergistic Yeast Postbiotic Blend, a multiple-strain postbiotic that can support your pet’s normal immune defenses.

Frequently Asked Questions

The probiotic blend included in our soft chew is made up of prebiotics, probiotics, and postbiotics — all of which come together to support your dog’s gut. Considering about 70% of your dog’s immune cells live in their gut, this in turn supports their immune system. 

Our Allergy & Immune soft chews offer a unique, triple-action formula that targets your seasonal dog allergies while also supporting gut and immune health, as well as promoting a healthy skin and coat. Unlike standard supplements, these soft chews include a blend that includes probiotics for dogs, formulated to support your dog's gut health, which is fundamental to their immune response. This advanced formula integrates prebiotics, postbiotics, potent antioxidants, omega fatty acids, and colostrum, offering a simple approach to managing occasional dog allergies.

These soft chews are designed to target occasional discomforts associated with seasonal and occasional allergies. They support a healthy immune response, maintain gut health, and contribute to a lustrous skin and coat. By providing the best dog probiotic blend for your pup, this multi-faceted approach ensures your dog receives a broad spectrum of health benefits in one daily soft chew.

Currently, our Allergy & Immune soft chews are available in a pork flavor that's a hit with dogs. We're always looking to enhance our product line, so additional flavors may be introduced in the future.

Our soft chews are made to accommodate a variety of dietary preferences. However, if your dog has specific allergies or dietary restrictions, please consult with your veterinarian before adding new supplements to their diet to ensure safety and compatibility.

As you may know, it may take time for supplements to produce results. In an internal survey that we conducted, we found that 83% of Probiotic Chew subscribers surveyed saw benefits within 3 months of daily use1. That shows the power of consistency!

Benadryl, the brand name for diphenhydramine, is a drug and should only be administered under veterinary supervision. Please consult your vet before giving your dog Benadryl.

We recommend introducing Allergy & Immune Probiotic soft chews to your pup’s daily routine slowly when they are over 12 weeks old. If you have any questions, please speak to your veterinarian.

If you accidentally give your dog too many soft chews, see a veterinarian as soon as possible. If you’re unsure how many soft chews to give your dog, please see the Directions for Use on the product label.
