Most pet owners would admit they have at one point or another felt the temptation to reach out to their medicine pack to treat their dogs without any supervision from a vet and this can be very dangerous. In this article, we would be giving you everything you need to know about benadryl for dogs.

Just like how humans react differently to medications, dogs are no exception and that is why a vet would always caution a pet owner to not make independent decisions when it comes to their pets medications. Regardless, there are some human medications that are safe to use for dogs as long as they are used in the right way.


Veterinarians make use of benadryl for dogs on a regular basis in treating dog allergies and sometimes travel anxiety as well as motion sickness in some cases. Even though you need to consult your vet before giving your dog medications meant for humans here are still a few things you need to know about the use of benadryl for dogs.


What is Benadryl?


Benadryl is also the brand name for an active ingredient called diphenhydramine HCL. Diphenhydraime is also considered as part of the first generation ethanolamine-derivative antihistamine which is also a scientific way of classifying antihistamines that are capable of crossing the blood brain barrier from the ones that cannot. Benadryl is also an over-the-counter antihistamine that is used to calm allergic reactions to environmental allergens, insects stings and also bites as well as some vaccine reactions.

This drug is a human drug and it is not approved for dogs and other animals by the FDA but you can also give it to your dog only with approval from your vet. Benadryl is not the only drug that can be used to treat allergies. There are other brands that make drugs that you can use to treat allergies and there are also some drugs under the Benadryl brand you must also avoid if you have no knowledge about it.


Before giving a medication to your dog, you should always read the ingredients of the medication. Diphenhydraime is the ingredient active in Benadryl that is considered safe for canines. You could also see certizine as well and it is safe for dogs as well but while it may be safe, there is really no need to expose your dog to it if it is not necessary.


Products that contain ingredients like acetaminophen and pseudophedrine should not be used for your dogs because they are not safe for them as they are very toxic to canines. Benadryl can also be used for other animals like cats and it is used by many vets across the United States Of America.


How does Benadyrl work?


Diphenhydramine is considered to be a receptor antagonist which also means that the drug works by blocking the receptors that receives histamines in the body. This process helps relieves many of the symptoms associated with certain allergies like itching, sneezing and many more.

Mind you, you should not ignore the fact that the body still produces histamines but the receptor antagonist will block the receptors from registering the histamines. An example to better understand this process is taking a basket of food for example, imagine a full basket of food that more food is being added, the excess food just falls out because there is no room for it anymore.


When to ask your vet about benadyrl for your dog


Before going ahead to get the Benadryl, first you should consult your vet about the symptoms your dog is exhibiting. Some allergy symptoms like itching and red eyes can also be signs of a very serious condition. Giving your dog Benadryl in some cases can worsen the dogs condition especially in some cases like glaucoma.


As much as red and goopy eyes can be a symptom of allergies, it would also be a sign of an eye disease like glaucoma mentioned earlier and Benadryl cannot help treat the disease. Also when your dog is itching it could signify an allergy and it could also be because of a skin condition. Make sure you always consult your vet before making any moves on medicating your dog so as to make sure you are doing what is best for your dog.


In some cases your vet might recommend you bring your dog in for checkup from time to time and if you choose to go against the vets advice and not bring your dog in or if you try to administer Benadryl to your dog without the vets consent just make sure you are keeping a close eye on your dog. Make sure you also call your vet if your dog’s condition worsens.


Dosage


The ideal dosage of the Benadryl for dogs is 1mg for every pound of body weight of the dog. However, before you even administer any drug to your dog make sure you are consulting your vet first as so many factors can change the dosage recommendation for your dog.


The average dosage a tablet contains is about 25mg so by calculations a 25 pound dog would only need one tablet of Benadryl. But any precaution you should take is also by checking the dosage on the package because not every product would have the same dosage on a tablet.


Make sure you are using the tablets for your dog and not the liquid form of it because the liquid form may contain alcohol and alcohol is not good for your dog.


When you want to give a smaller dog the Benadryl make sure you use the children’s formula as it has less of the active ingredient and it is always easy to measure. Also, the children’s formula of the liquid Benadryl has no alcohol.


The Benadryl also has a tropical form that can help with your dog’s itching. For this you should also consult your vet before using any cream or gel on your dog.


Ideally, you can administer the Benadryl to your dog every 8 to 12 hours so that is about 2 to 3 times every day. Also, watch out, if you use the product frequently your dog’s body will build resistance to it and it would start to lose effectiveness overtime.

In most cases, the best option is to use to use the drug before your dog is exposed to allergens. You should also follow your vets guidelines and if they recommend a regimen make sure you stick to it for the duration proposed by your vet even if the symptoms go away.


Initially, Benadryl takes about 30 minutes before it starts working so when you want to use it for your dog, plan accordingly especially when you want to use it to treat anxiety or mild motion sickness. For dogs that have very serious allergies or even conditions that would require them having daily doses of Benadryl, make sure you consult your vet about the appropriate dosage as it is subject to change.


If your dog is pregnant also consult your vet before giving Benadryl to them as they are not recommended for use in these animals.
