Benadryl is a common over-the-counter medicine that you can occasionally find in your medicine cabinet. The active ingredient in Benadryl is Diphenhydramine Hydrogen Chloride, an antihistamine that is intended to relieve humans from allergies or allergy-like symptoms. However, numerous veterinary doctors have been prescribing a certain dosage of Benadryl for dogs and cats alike. It is a readily available over-the-counter drug that has been noted to calm down health concerns pet parents have when proper dosage and care are being taken.
The question remains when and how much Benadryl you can give to your dog. Let us walk you through the process.
It should be noted that Benadryl is simply the name of the company that sells the drug and not the actual drug. Thus, while purchasing Benadryl for your dog, the composition of the tablet must be checked first.
The general rule applies; the dosage for your dog is determined by the weight of your dog. That said, according to Pet MD, for every pound your dog is allowed 1 mg of the medicine. It is always best to remain on the safe side and start with a smaller dose. The frequency should always be with a gap of 6 – 8 hours between the administered doses.
Here’s the dog benadryl dosage chart to keep things simple.
And a table keeping track of all the different forms of Benadryl:

Benadryl, although not FDA-approved for animals, has been known to cure a variety of symptoms in dogs and even cats.
Veterinary doctors prescribe it for the following symptoms:
Seasonal allergies or even bee stings can be treated with Benadryl. It reduces the effects of allergic reactions by preventing the uptake of histamine in the body. Thus, it can be used to relieve symptoms of watery eyes, inflammation, and certain rashes on the skin.
Certain dogs tend to get agitated or overwhelmed by loud noises. The calming properties of Benadryl come in handy in situations like these; thunderstorms or firework season i.e. the fourth of July.
Reaction to insect bites and discomfort may be cured by a dose of Benadryl
One of the common side effects of Benadryl is drowsiness, the Nytol present in the compound can help put your dog to ease and eventually fall asleep.
During travel or any sort of trip, motion sickness can be avoided by Benadryl. The active ingredient Diphenhydramine treats nausea and thus, blocks the part of the brain that could cause your dog to experience motion sickness.
One tablet of Benadryl is usually 25 mg. If you’re trying to give it to your dog in the form of a tablet, it would be wise to hide it in his food, or a treat, so that he takes it willingly and swallows. Saving you the struggle.
This form is essentially the easiest way to administer to canines. The children’s formula version contains zero alcohol hence making it safe for your dogs as well. The low composition of Benadryl in the formula also makes it easier to measure dosage for puppies and convenient to administer.
Restricted use of topical Benadryl can be applied directly to your dog’s rash on the skin. It will relieve discomfort. However, prolonged use is not recommended for canines.
Under emergency circumstances, veterinary doctors may administer an injection of Benadryl to your pet dog.
Benadryl in liquid form is not safe for dogs as it contains alcohol. Avoid it at all costs.
