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.
