Description: PetArmor Antihistamine Tablets contain diphenhydramine HCl, the same active ingredient found in human Benadryl Allergy Ultratabs, formulated specifically for dogs at a lower cost than many name-brand alternatives. The tablets are intended to provide temporary relief from sensitive, itchy skin, insect bites and stings, and mild travel-related anxiety, making them a common first-line, at-home option before a vet visit is needed for non-urgent symptoms. Dosing is weight-based — the label recommends 1 tablet twice daily for dogs 14–30 lbs and 2 tablets twice daily for dogs over 30 lbs — and the manufacturer advises consulting a veterinarian first for dogs under 14 lbs. As with any antihistamine, individual dogs can react differently, and owners should read the full label and monitor their dog after the first dose. This is an over-the-counter product, but persistent, severe, or worsening allergy symptoms warrant a veterinary exam rather than repeated at-home dosing.
