Frequently asked questions

Probiotics promote gut health and a healthy immune system in dogs to target seasonal allergies at the source. A balanced gut can optimize the immune response, support a dog’s normal defenses, and help maintain normal histamine levels to keep occasional discomfort at bay.

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 a high-quality 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.

Seasonal dog allergy soft chews formulated with probiotics can be a helpful tool for pet parents whose dogs experience discomfort from occasional allergies. These health supplements support a dog’s immune response and help to maintain normal histamine levels. You should consult your veterinarian before using any seasonal dog allergy supplement if you are unsure.

As you may know, it may take time for supplements to show benefits. In an internal survey that we conducted, we found that 84% of PetlabCo. subscribers surveyed saw benefits within 3 months of daily use.* That shows the power of consistency!


*Results based on PetLabCo. Probiotic Chews, Joint Care Chews, and Dental Formula subscriber feedback survey conducted in March/April 2022 (n=615).

Our research-backed seasonal dog allergy supplement offers a triple-action probiotic formula that supports a dog’s immune system and their digestive health. Plus, other powerhouse ingredients like colostrum, borage oil, krill oil, and vitamin E all work synergistically to support your dog’s skin and coat. PetLabCo. Allergy & Immune is tailored to small, medium, and large dogs, so you can select the size and quantity based on their weight.

PetLabCo.’s Allergy & Immune soft chews are suitable for all dogs 12 weeks and older. If you have any questions about giving these seasonal dog allergy soft chews to your puppy, please contact your veterinarian.

Yes, dogs can (and do!) develop seasonal allergies – just like people do. Certain environmental triggers can lead to occasional allergies in our canine companions. Signs of seasonal allergies in dogs may include occasional watery eyes, tear stains, itching, paw licking, skin sensitivities, and sneezing. We recommend reaching out to your veterinarian if you suspect your dog has seasonal allergies.

Our delicious Allergy & Immune soft chews are pork flavored, and dogs love the taste! 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.

Colostrum is a protein-rich fluid produced by mammary glands. When added to supplements for dogs, this ingredient can support good gut microbes and healthy skin. The colostrum in PetLabCo. Allergy & Immune seasonal dog allergy supplement is bovine colostrum — meaning it comes from cows. 

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.

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.

Our Allergy & Immune soft chews were specifically formulated for dogs and should not be given to cats. If you are looking for something to support your feline’s gut health, our newly launched Cat Probiotic is a great option!

Our Allergy & Immune Chews have a shelf-life of 12 months.

Products may be returned for a full refund within 30 days. Your return must be unopened and in the same condition that you received it.

Our inventory system ensures we maintain a ready supply of our Allergy & Immune Chews to meet demand, even during peak seasons.
