My Vet advised us to use Childrens Benadryl(liquid).  I usually use it dose for allergic reactions to bee stings, etc.

I used the melting sheet kind of Benadryl for my 12 pound poodle. That way it was easy to dose, and easy to put into her mouth. She was attacked by a swarm of yellow jackets, and her eye got all swollen. I felt I didn't have time to consult with a doctor, and that I needed to get some antihistamine into her right away.

The dosage is actually 25mg per 25lbs so if you have a 4lb dog the dose would be less than half of what the previous advice, so it's really always best to call the vet, they will give you this info for free and may even calculate the exact dose for you.

From the Merck Veterinary Manual benedryl should be used at the following doses. The doses listed on your site are way low.



*Diphenhydramine: can, fel-4 mg/kg PO TID, 0.5 mg/kg IV, IM BID.  

Antihistamine.



Kg = weight of dog divided by 2.2.

So an 50# dog would get 90mg and 80# dog would get 145mg. And that would be 3 times a day.

Actual dose 4mg/kg

For a 4# dog that is 7.27mg TID

We just took our 60 pound Doberman to the vet for a bee sting reaction. She said we should give 50 mg to our dog. The site is correct according to the vet.

I have used liquid Benadryl for yrs. The Equate one and have had no adverse effects. Most of my babies are 10 lbs and under. I use very little and it does the job. Have such small babies nothing is out there really for their size. I have to pay big money because I can't use generic. When the item says for 25 lbs and under, forget it.

Alot of the new liquids do not have alcohol in them so  are safe. Childrens benadryl is what my Vet recommended for a hyper Sheltie. She said 1ml per pound is best.

Childrens Benadryl D contains NO Alcohol or sugars... Also, I think a dose of 2mg per kg is pretty safe....

It's IMPORTANT to know the difference between mL and mG.  If one is to give 25 mG, that would only be two teaspoons of Benadryl...don't make the mistake and give 25 mL which is 1/4 of the bottle!!!!  Thanks.

FYI - I read on the AVMA website that Benadryl should not be used for snakebite.  I would do more research before giving my dog an antihistamine for a snake bite.

According to a Vet, the dosage for Dogs is 1mg per pound.  Here is a link to that doseage information.

I WAS TOLD BY MY DOGS VET THAT LIKE WITH HUMANS IT CAN CAUSE SEIZURES, WHICH IT DID IN MY 16 LB COCKAPOO

SO BEWARE. I WAS TOLD BY MY VET TO GIVE BENEDRYL IN THE FIRST PLACE

Actually the dosage is 1 mg per pound as needed up to every 8 hours, so if your dog is 4 pounds, it's 4 mgs, NOT 10 mgs like was in the list.  That would be more than double the proper dosage.


LovesDogs wrote at 2010-03-26 11:02:11
The chart on here says 10 mg for dogs under 30 pounds. But 10 mg. is too much for a 4 pound Chihuahua, which is what the original poster asked about in her question. The dosage is 1 mg. per 1 pound of dog. So her Chihuahua should have no more than 4 mg. of Benadryl.

I noticed in the answer above that you shouldn't give your dog liquid Benadryl (Diphenhydramine). Our home has dogs and children in it, so of course we have Benadryl. You can get the medication without alcohol. Just read the label and the ingredients. The kind we get is Children's Benadryl. Still look for the alcohol free sign, just to be safe. Hope this helps someone.

I have to give one of my Chihuahuas' benedryl every day for his allergies (during the summer).  I use children's benedryl because it has no alcohol but be advised the dosage is much lower than adult benedryl, but the adult contains alcohol.  I experimented a bit, because the 1ml per pound just sounded excessive.  My dog is a standard Chihuahua and 16lbs.  I give him 5ml twice a day and his allergies stay at bay.  I would follow the 1ml per pound dosage recommendation in cases of stings etc.  I figure if less works, it's better on his system than introducing MORE chemicals his liver and kidneys have to filter.

I just wanted to add to a few bits of information that I feel are incorrect. benadryl for snake bites will most likely not work and could actually do harm. most common snake venom is somatic or neurotoxic, not histaminic. Also, even though much larger than a human dose, since metabolized differently, the dose for dogs is 1mg per pound three intervals daily.


Mattie wrote at 2010-08-28 06:02:42
Regarding Benadryl and snake bite. It is used a lot for venomous and nonvenomous snake bite. It is used to control the swelling that can be very severe. It is not used in place of an antivenin but along with antivenin. In instances of snake bite the Vet may give antivenin to counter act the venom, Benadryl to control the swelling, Clavamox to prevent infection and Tramadol to control pain. Venomous snake bite is not something you should attempt to treat on your own.


KK wrote at 2010-09-16 00:50:24
I would not suggest giving a 4 pound dog that is a breed prone to reactions, 25 mg of benadryl. A VET will tell you to give around 1/2 mg per pound up to 1.5 mg per pound. always start with the lowest dose in that benadryl is an anti cholinergic drug and can cause serious side effects if over dosed. It can cause rapid, shallow breathing, agitation, tachypnea (rapid breathing which is not effective) and tachycardia (an abnormally high resting heart rate). Always be careful when giving an animal medication in that their bodies do not react the same as ours. Give the lowest dose first just like you would a child. only give more after speaking to a vet or if you are experienced in pharmacology!


Jamie wrote at 2011-04-17 02:00:14
Venomous snake bites are an emergency and it is not recommended to treat snake bites with Diphenhydramine(aka: Benadryl)unless recommended by your pets veterinarian.

PLEASE PLEASE, GO BY YOUR INSTINCTS, MY ENGLISH BULLDOG WENT INTO SOME KIND OF RESPIRATORY DISTRESS. HE SOUNDED LIKE HE WAS HAVING TROUBLE BREATHING. SEME HAD TROUBLE WITH HAVING REACTIONS TO THINGS. (WE HAD BEEN OUTSIDE EARLIER AND HE ACTED LIKE HIS BACK WAS HURTING I GAVE HIM 1/2 OF RAMODYL FOR PAIN.) ABOUT AN HOUR OR 2 LATER. I THOUGHT HE WAS HAVING A REACTION TO THE PAIN PILL.  I GAVE HIM 50MG OF BENEDRYL, HIS VET HAD ORDERED 2 TO BE GIVEN AT A TIME. I ONLY GAVE HIM ONE! HE DID NOT RESPOND TO IT SO I GAVE HIM THE 2ND ONE. A TOTAL OF 100MG! I FELT LIKE THAT WAS TOO MUCH. BUT WENT BY THE DIRECTIONS ON THE BOTTLE FROM HIS VET. HE CONTINUED TO GET WORSE HAD TO TAKE HIM TO OUT OF TOWN ER VET HOSPITAL. THEY GAVE HIM ATROPINE HE CODED AND DIED WITHIN 20MINUTES. I WILL ALWAYS BLAME MYSELF FOR THIS. I FELT LIKE THAT WAS TOO MUCH BENEDRYL. HE WEIGHED 54 POUNDS AND WAS 7 YEARS AN 7MONTHS .. SEME HAS BEEN GONE ALMOST A YEAR. I MISS HIM SO MUCH. GOD BLESS YOU ALL. MAY Y0U NEVER EXPERIENCE THIS..NO ONE COULD EXPLAIN THE CAUSE OF HIS DEATH. ONLY THAT HIS HEART STOPPED. ONE VET THOUGHT AFTERWARDS THAT HE WAS HAVING A HEART ATTACK. THE OTHER THOUGHT IT WAS AN ALLERGIC REACTION TO SOMETHING  THAT SET OFF A SEVERE ASTHMATIC ATTACK WHICH RESULTED IN DEATH! EVEN THOUGH MY VET SAID HE GOT THE RIGHT DOSAGE. I STILL FEEL LIKE IT WAS TOO MUCH..

This was extremely helpful.  I have a small dog who weighs 35 pounds. His skin is so itchy and and he has taken the hair off in several places. Took to vet and she said Benadryl would be the best. She said could give something else but to save money Benadryl would be the best

I have owned dogs my whole life. I was a veterinarian assistant for several different vets, so I might be able to help out on health issues. Although I love all dogs, my favorites are the toy breed. I am not a breeder, so those type of questions should be directed to someone who is. I have three chinese crested, two chihuahuas and one yorkie/silky mix. I would be happy to answer any questions on these particular breeds,or just dogs in general. Please keep in mind,however, that I am NOT a Veterinarian. If you feel your dog is seriously ill, then please take your pet to a qualified professional. Although we "experts" try to help you with your questions, it is impossible to "see" or "touch" your dog through a computer. If you feel your dog's life is in danger, please call a Veterinarian immediately. Thank you!
