Benadryl is a brand name for the drug: diphenhydramine, which is an antihistamine. Antihistamines work by blocking the effects of the naturally occurring chemical histamine in the body. Histamine is often produced during an allergic reaction. Benadryl is used for many different reasons:

  • Decreases cold-like symptoms: sneezing, runny nose, watery eyes, or itching
  • Reduces hives and skin rashes
  • Prevents or treats allergic reactions and symptoms
  • Treats motion sickness or to induce sleep
  • Occasionally used for symptoms of Parkinson’s disease.

What Can Benadryl Be Used to Treat in Dogs?

Just like humans, antihistamines can be used to treat similar allergic reactions in dogs. The important aspect is to know whether your dog is having an allergic reaction or has chronic seasonal allergies. In addition, dogs may exhibit different symptoms that may not mimic those of humans, so it’s vital to know what to look for. In most cases, dogs who are having an allergic reaction may exhibit symptoms on the skin’s surface or have difficulty breathing.

Although your furry friend can show signs of allergies that are similar to those of humans, you’ll want to make sure that your pup doesn’t have a more serious condition at hand.

If you notice nasal discharge, coughing, or inflamed, reddened eyes, these can all be signs of a respiratory infection. Therefore, remember not to assume your pet’s allergies are causing these symptoms.

You may be thinking, “what is Benadryl for dogs?” and is it safe for you to give Benadryl to your pet?  It all comes down to getting a comprehensive evaluation from your vet. If your fur baby is indeed suffering from an allergic reaction, your vet may recommend daily doses of Benadryl for dogs.

Signs and Symptoms of Allergies in Dogs

As we mentioned, the below signs and symptoms of allergies in dogs can also be indications of more serious illnesses. Don’t automatically assume any of these are just signs of allergies. However, if your vet notices these common symptoms, they may recommend treating them with an antihistamine like Benadryl. Some of the signs and symptoms of allergic reactions in dogs include:

  • Sneezing
  • Red or watery eyes
  • Nasal congestion or drip
  • Coughing or hacking
  • Frequent awakening
  • Difficulty breathing
  • An audible whistling or wheezing sound when exhaling
  • Raised, red patches of skin known as hives
  • Eczema or itchy skin

Seasonal Allergies vs. Food Allergies in Dogs

There are many things in your home that may trigger an allergic reaction in your dog. Some of these may include:

  • Dog bed stuffing or other fabrics
  • Food allergies to treats, bones, or toys
  • Other pets in the household
  • Mold or dust mites
  • Doggy shampoo or conditioner
  • Indoor plants
  • Essential oil diffusers or fragrances in the air
  • Smoke from candles or cigarettes

It’s recommended to do a “trial and error” of what could be triggering your pet’s allergies. In addition to removing items from your house that might be causing allergies, the best advice is to clean thoroughly, wash the bedding often, and clean with all-natural products with no chemicals. Your vet may recommend Benadryl for dogs who have chronic allergic reactions to their environment.

On the other hand, food allergies will be dealt with by changing food brands or styles, not with Benadryl. This may include eliminating or adding grains, switching from different meats, or investigating other additives that could be in your pet’s regular food.

How Much Benadryl Should You Give Your Dog

The standard dosage for oral Benadryl for dogs is 1 mg per pound of body weight, given two to three times a day, or as needed. Most average diphenhydramine tablets found at the drugstore are 25 mg, which is the size used for a 25-pound dog. If you’re not sure how much Benadryl to give your dog or what kind of Benadryl is safe for dogs, make sure to contact your veterinarian. Below, we have included an easy to read, Benadryl for dogs dosage chart which can help you determine how much Benadryl to give your furry friend.

As one of the most enthusiastic dog lovers in the Chicagoland suburbs, Jenna spends her free-time snuggling and exploring the wilderness (many dog parks and forest preserves) with her best friend, Rudy. Rudy is an adopted Tibetan Terrier mix who enjoys lounging around the house, begging for table scraps, and receiving his daily butt rub. With his black and white coat, curly tail and smelly toots, Rudy is often referred to as our little skunk. Rudy’s favorite past-time is barking at the waves created by our paddle boat and chasing the pesky rabbits out of his yard. We are enamored with him and can’t believe how lucky we are to call Rudy our furbaby.
