Benadryl and Dog Anxiety

We’ve answered the questions, “How much Benadryl can I give my dog?” and “Can I give my dog Benadryl for allergies?” But there are some other instances where diphenhydramine HCL is used for dogs. Here’s what you need to know.

Due to its side effect of drowsiness, some pet parents use Benadryl as a mild sedative for anxious dogs in overwhelming situations like vet visits, car rides, fireworks, or thunderstorms. The Merck Veterinary Manual states that Benadryl may relieve symptoms of mild-to-moderate anxiety in dogs, especially during travel.

If you have a pooch with anxiety, you might also want to consider a natural calming supplement. Calming hemp-based chews, for example, can help make stressful situations less of an anxiety-inducing process. Look for a dog supplement that has soothing active ingredients such as chamomile, ginger root, passion flower, and hemp oil. These ingredients work together to curb your dog’s anxiety by creating a calming effect.

  • What Does Benadryl Do?

    Benadryl is an over-the-counter antihistamine that also goes by its generic name, diphenhydramine HCL (this is also its active ingredient). Benadryl can help alleviate allergy symptoms in both you and your dog that come from seasonal allergies, environmental allergies, food allergies, and insect bites.

    According to Catherine Barnette, DVM, and Ernest Ward, DVM of VCA Hospitals, the most common sign of a dog with an allergy is itching of the skin. Skin conditions can arise in conjunction with respiratory symptoms as well. “In some cases, the symptoms involve the respiratory system, with coughing, sneezing, and/or wheezing.”

    Both the brand-name Benadryl and other diphenhydramine medications typically come in tablets of 25 milligrams. Luckily, the math involved to determine the proper Benadryl dose for dogs is quite straightforward.
