      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.

      How long should I use it for to see benefits?

      *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.®’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.

      Can dogs have seasonal allergies?

      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.

      What flavor are PetLabCo. Allergy & Immune chews?

      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.

      Should I be aware of any dietary restrictions when giving my dog Allergy & Immune soft chews?

      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.

      What are the benefits of colostrum for dogs?

      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 inPetLabCo.®Allergy & Immune seasonal dog allergy supplement is bovine colostrum — meaning it comes from cows. 

      What happens if I accidentally give my dog too much Allergy & Immune Probiotic soft chews?

      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 for dogs? What is the recommended Benadryl dosage for dogs with seasonal allergies?

      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.

      Can PetLabCo. Allergy & Immune soft chews be given to cats?

      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!
