What is Benadryl?

Now let’s talk about Benadryl specifically.
Benadryl is a common name for diphenhydramine. Diphenhydramine is an over-the-counter (OTC) drug often used to treat allergies, hay fever, and other conditions that cause symptoms of sneezing and congestion. It can also be used to help with insomnia or the itching caused by hives. Benadryl is a type of allergy medication that has been used in dogs for the last few decades. It’s typically used to help with allergies and as an anti-inflammatory, but it can also be used as a sleep aid.

Can Dogs Take Benadryl for Anxiety? Can Benadryl be used for dog allergies?

Benadryl is often prescribed for allergies, itching (e.g., atopic dermatitis), motion sickness and nausea (e.g., from car rides). The drug may also help with anxiety-related problems such as thunderstorms and fireworks displays because Benadryl works to reduce both physical symptoms such as excessive drooling or shaking but more importantly the mental ones like fearfulness or aggression which are closely related to anxiety disorders in humans.

Benadryl Safety: Which Dogs Can’t Have It?

Certain dogs can’t have Benadryl, the active ingredient in medication for humans. A dog’s age and size are important factors when determining whether or not they should take Benadryl, as well as how much are taken at one time. These are some of the breeds that shouldn’t be given Benadryl: Akitas, Alaskan Malamutes, Bull Terriers, Doberman Pinschers, Great Danes and Irish Setters. In addition to these breeds, it is always best to consult with your vet before giving any human medication to your pet. If you do decide to give them a human medicine, make sure you understand all of its potential side effects on pets before administering it.

What’s the Benadryl Dosage for Dogs?

Benadryl is not a cure-all medication but it can help treat symptoms associated with all types of allergic reactions in both cats and dogs. The recommended dosage depends on your dog’s weight:
Dogs weighing less than 15 pounds: 1 millilitre (ml) or 5 drops every 6 hours
Dogs weighing between 15 and 49 pounds: 2 ml or 10 drops every 6 hours
Dogs weighing more than 50 pounds: 3ml or 15 drops every 6 hours
The dosage of Benadryl will depend on the weight of your dog and its condition.
The average dose for dogs may start at 1mg per pound given orally every 8 hours as needed but some dogs may need more than 2mg per pound if they are experiencing significant itching or discomfort from any allergic reactions.

Benadryl Tablets or Liquid Benadryl?

It’s available as tablets and liquid. Usually given orally, it can also be given by injection if the dog cannot swallow it. Liquid Benadryl comes in a dropper bottle and the dosage can be measured by eye drop measurements on the side of the bottle. The same medication is found in Benadryl tablets which are capsules that come in various strengths such as 12.5mg or 25mg.

How many Benadryl tablets should I give my dog?

It’s important to know how many milligrams of the drug you’re giving your pet, so it can be accurately dosed. To find out how many milligrams are in each tablet size, divide the weight (in milligrams) by the number of tablets per pound. So if there are 10 tablets per pound and you have a 25-pound dog, that means every 2.5 pounds counts for one pill size. That would mean five pills total as an initial dose for your pup! If this dosage doesn’t help with allergy relief after two weeks, talk to your vet.

How much liquid Benadryl should I give my dog?

It’s important to understand how much liquid Benadryl you should give your dog in order to avoid giving too little or too much. If you are unsure, contact your vet for advice on administering the correct dosage. Here is some information about the right amount of liquid Benadryl for dogs: -A typical 10-pound dog needs 1 teaspoon (5ml) every 12 hours, a 20-pound dog needs 2 teaspoons (10 ml) every 12 hours, and a 40-pound dog needs 4 teaspoons (20 ml) every 12 hours. -Most veterinarians recommend that dogs under ten pounds receive half of the recommended dose from this chart. These amounts can be adjusted depending on the severity and duration of symptoms as recommended by your veterinarian.

What are the side effects of Benadryl?

Some side effects include drowsiness, dry mouth, nose congestion, and urinating less than normal. These are all common side effects that go away after stopping a treatment or if you reduce the dosage. They may also vary depending on how many other medications your pet takes or what type of food they eat. If you’re concerned about these you should first consult with your vet.


Benadryl is one way to help combat allergy symptoms without having to use prescription drugs or steroids. One thing is for sure though-Benadryl will not harm your pup! We hope you find this information helpful in determining what would work best for your furry friend!
