Benadryl for Dogs: The Do’s & Don’ts, Dosage, Side Effects, And More

Benadryl for Dogs If your dog or emotional support animal suffers from severe allergies or allergic reactions to things around them, then you know how hard it is to watch them go through that pain. However, there is a solution: Benadryl for dogs.

“What, you say?! This ‘human drug’ can be used on dogs?! I’m not sure about that…”

Benadryl is an over-the-counter drug, most commonly known as an antihistamine, and helps alleviate the symptoms that your dog may have in regards to allergies, allergic reactions, insect bites, itching, and more.

First Things First, Is Benadryl for Dogs Safe?

YES!

Benadryl contains an active ingredient called diphenhydramine that is safe for your pet to ingest, unlike other cold, sinus, and antihistamine drugs.

Its purpose is to help alleviate the symptoms of allergies, allergic reactions, anxiety, motion sickness, bites, and much more to give your dog a more relaxed and stress-free lifestyle.

As with any new medication, however, it always pays to observe your dog closely after the dosage has been given for the first hour. The reason being is that they may suffer from symptoms that occur with the medication, or it may, in fact, irritate the dog’s skin and cause their allergic reaction to get worse.

If you are unsure that Benadryl is safe for your dog to take or they have conflicting conditions, then please consult your local veterinarian before exposing them to the medication.

Diphenhydramine: Benadryl’s Most Active Ingredient

Diphenhydramine is an active ingredient that is found in Benadryl. It acts as an antihistamine that reduces the effects of chemical histamine that is found in your dog’s body.

Diphenhydramine works to reduce and target runny noses, skin rashes, sneezing, watery eyes, itching, allergic reactions, motion sickness, and other allergy symptoms.

It also helps to induce sleep to give your pet some relief at night and is one of the reasons why it is prescribed a lot to help your dog with anxiety and the symptoms that come with it.

Benadryl for Dogs: What’s Its Purpose?

Benadryl for dogs is a medication that helps to alleviate mild-to-moderate allergies in your dog. The active ingredient of diphenhydramine targets a range of different conditions and symptoms that your pet may be suffering.

These include:

Allergies + Common Cold for dogs

Diphenhydramine’s purpose is to eliminate allergy symptoms that your dog may be suffering. These can include:

  • Hives
  • Itching
  • Coughing
  • Sneezing
  • Swelling + inflammation
  • Redness
  • A runny nose + eyes

Bites

If your dog has been bitten by something that has caused the area to swell up or inflame, then Benadryl can help alleviate that. Diphenhydramine is also useful if your dog is experiencing an anaphylactic reaction from the bite as it targets the chemical reaction that causes this to happen.

Anxiety

One of the side effects of giving your dog Benadryl is drowsiness. This is because of the active ingredient of diphenhydramine and can be used for dogs that suffer from anxiety as it helps to calm them.

Other Purposes

Benadryl is an all-around type of medication and can be also used for a number of different conditions and symptoms. If your dog suffers from motion sickness during car and plane rides, Benadryl can help to alleviate that.

It is also used as therapy medication to other conditions such as tumors. Benadryl has been known to help mitigate the effects of the massive histamine release that is caused by mast cell degranulation. In some cases, veterinarians can also prescribe diphenhydramine to help treat heartworm.

  1. My dog is post-surgery. He is on antibiotics and Trazodone (for sedation). He is still agitated with the E-collar and has been neurotic about chewing and licking the incision. This is the second time he has had surgery. First time to remove a tumor and the second to re-suture the incision after he removed the stitches from the first surgery. He now has staples but is still trying to remove them. I would like to give him Benadryl along with the Trazodone. Do you know if it is safe to mix Trazodone and Benadryl in dogs? I don’t want to increase his dosage of Trazodone, but his neurotic licking and chewing is tearing up the incision. I would like to add the calming effects of Benadryl.

  2. How much Benadryl should I give?
    The standard dosage for oral Benadryl is 1 mg per pound of body weight, given 2-3 times a day. Most drug store diphenhydramine tablets are 25 mg, which is the size used for a 25 pound dog. Always double check the dosage before giving an over the counter medication. In addition, many formulations are combined with other medications such as Tylenol so make sure Benadryl tablets contain only diphenhydramine.

  3. Good grief…. I thought I was reading an article that would benefit my pet, not a freakin English lesson… give me a break… where is your article so it can be critiqued Ms. Pomeroy?

  4. Proofread. It degrades your credibility when there are grammatical errors. Otherwise, very helpful. Thank you!
