Anyway! Back to Benadryl.

Put in very plain words, Benadryl or diphenhydramine, as generically coined is an over counter drug that is kind of antihistamine.

Give me that Benadryl!

If so, what is the right Benadryl dosage for dogs?

Here is the deal! Let’s first tackle the very first part of your question:

Can I use it for dog?

Generally the answer to this question is YES! Considering all the health conditions mentioned above that this magical drug can rid your puppy of, we definitely recommend it.

But don’t take this as an invitation and use it on a daily basis.

No! That’s the sure fire way to get your puppy illnesses you won’t be so much happy about.

So, you need to pick up the right Benadryl product.

This is the very first thing you need to pay attention to! Not all products claiming to contain Benadryl are good!

Opt for products that contain nothing but Diphenhydramine. And stay away from products with Cetirizine, Pseudoephedrine and Acetaminophen. These are toxic substances and can do major damage to your dog.

Sometimes, they may lead to health conditions that will leave your dog with very serious conditions. They may lead to liver damage, blood pressure and worst of all, an increased heart rate!

Here is a complete guide to deepen your knowledge.

This video from YouTube further explains whether or not it is safe to give it to your dog. 

Now that you know that it is safe to use Benadryl for your dog, given that you know how to pick up the right Benadryl product, it is time to get into how much is enough and how much is too much.

In other words:

What Is The Right Benadryl Dosage For Dogs?

Easy! Easy, Mr. Vet!

Look! This is the very first thing you need to know. Don’t do anything on your own. The guidelines below are not to be taken as a substitute for your vet advice. No. Never do that. You are dealing with a creature. Slightest mistakes may lead to serious problems.

So, please take your vet advice first.

Here is what we suggest though.

You first need to check your dog weight. This way, you will know what you're doing.

Opt for 25 mg for a 25 pounds dog.

But there are situations where 25 mg dose can’t do much good to your dog body. Let’s say for instance, God forbids, your dog is bitten by a snake. That’s just an example. No need to panic. In this situation, a single tablet is really not going to help your dog's body recover.

You need to at least double it.

Now, off to the very last question:

How Often Should You Give The Drug To Your Dog?

Of course, opinions vary on that matter, depending on a variety of reasons. But generally, vets advise that you give it to your dog between 2 to 3 times, spread out between at least 8 hours.

Don’t fall to the trap of stopping the medication once you see your dog getting better. If your vet is the one prescribed the drug for your dog, stick to the period he told you about and complete the medication.


There you have it guys! Benadryl is a good drug if you use it the right way. Now, would you mind doing me a pleasure? See that comment box below? Give it a hard punch to the stomach and let me know what you think about Benadryl? What else can you suggest we add? Cheers!
