Hydrogen Peroxide

I had bought a new Chihuahua puppy and within the first few days home, he developed a deep hacking cough (kennel cough), so bad he could not sleep. He only weighed 1.9 pounds so I did not want him vaccinated or put on antibiotics, but needed to stop the cough so he could sleep. I went on the internet and found many recommedations of hydrogen peroxide in water for it. I put about 3 drops of hydrogen peroxide in about a glass of water with some honey for sweetener and to coat his throat and immediately after drinking this he stopped coughing and slept. He only hacked once or twice after that, but not near as bad as before and by the next day he was well. One of my other dogs got it the next day and I tried it with her and it did the same thing, so I put it in my dogs water for a few days and my other 2 dogs never even got it. My daughter tried it too after having her dogs to a doggy daycare for a weekend and they came home coughing. It worked just as fast for her and has not returned. It was an absolute miracle. Now she puts it in their water for about 2 weeks before going to the doggy daycare and it prevents the kennel cough. After reading your site, I now know why it works, not just that it works. Thank you.

Kennel cough cured! Thank you, thank you, thank you! I tried the food grade hydrogen peroxide remedy. Just to be safe I diluted it to an extreme. I put 3 drops of the mixture in Shelby's water bowl and immediately (within a 2 days) she was almost completely cured. I had gone to a vet and was prescribed some expensive medicine that did NOT work at all. This natural remedy was nothing short of amazing!

I was at a loss as to what to do for my little yorkie who was suffering from what I believed to' be kennel cough and I read others' feedback and the hydrogen peroxide really works! Within the first hour he showed a significant improvement. I also gave him a bit of honey to help ease the cough and the combination of the two have really been a life and a money saver!

Hi. My comment is to Anthony with Snoopy the rescued Beagle. We have 2 Beagles (Copper and Bailey). Snoopy may also be experiencing the 'reversed sneeze'. Both of my Beagles do this every once in a awhile - it's looks like kennel cough. It's almost like they're about to vomit (heeving and coughing). As directed by a vet, you just have to hold their nose closed, making them breathe through their mouth. Sometimes I have to help Bailey open his mouth. Copper is an old pro at it. This opens the air passage that is causing the heeving by releasing the pallet that is caught in the throat. It's hard to do, but it works every time.

I have a 14 year old white boxer who developed kennel cough and after 2 vet visits and over 400 dollars later he was getting worse. I found info about food grade hydrogen peroxide curing kennel cough so my father in law got a bottle of it at a nature store and 3 days into giving it to my dog he is 50 percent better!!! I highly recommend it but do be careful on how much you give to much can be harmful. My dog weighs about 65 pounds and I give him 3 drops in 8 tablespoons of milk 3 times a day. Good Luck!!!!

My 12 year old dog has had an intermittant cough for some months now. It may not be a cough but an irritated throat (which is what the vet saw). Every so often he would get up from his bed making a sound as though something were stuck in his throat. This happened several times a day. I solved this problem by adding 2 drops of food grade hydrogen peroxide to his water bowl. This choking/cough stopped within a day. If I forget it comes back the next day.

I have a Chihuahua and half Corgi. He's about 10 years old he has his cough and gagging and clear foamy spit around another dog that has kennel cough so I just need to know what to do right now.
EC: Please read the posts on this pets/cough page. The most effective remedy reported is 3% hydrogen peroxide drops on a piece of bread or food.

I have used honey lemon and Peroxide mixture and it worked so good for my 13 1/2 year old Retriever. I was just wondering how long I can continue using Peroxide on her for since I have seen a huge improvement since using it.

Hi, I'm very interested in trying this home remedy for my 11 lb doggie. he's 14yo has an enlarged heart and taking "vetmedin" for this. this has caused another problem (gagging cough )for which he has been on "tussigon". IT works! However it is too expensive so Id like the exact portions or proportions of water, honey and food grade hydrogen peroxide so that I can try it out. Thanks so much!

Hello, I have 2 dogs on Tussegon and you are right. It is very expensive.
I did find that if you get the GoodRx app and sign up it will cut the cost in half. All pharmacies honor the GoodRx card and the app will tell you where you can get the medicine the cheapest.
It does work great with our maltese who has a cough due to heart disease.

I noticed that this post was originally started by an individual in British Columbia. The original post made reference to Food Grade Peroxide. From this I make the assumption there is a difference between H2O2 I would find in on the drug store isle and grocery store isle. Is this true in USA as well? If not, what isle at my local grocery should I look for Food Grade Peroxide or should I be planning a trip to health food store?

YES! When I adopted my 2nd Bichon from the pound, she had kennel cough. The vet was wanting to charge me 200 bucks for a medicine and told me that it usually doesn't work the first time around. I told him I would try myself and then bring her back if my rememdy didn't work. I found a chewable supplement for kids and gave her 1 wafer. She ate it without problem. A few hours later, she stopped coughing altogether. I even gave it to my first dog so that she wouldn't get sick. It works and it is cheap! Anytime I use any kind of human supplement on my dogs, I use a child formula as it helps with taking the guessing out for dosage because children's medicine/vitamins usually give dosages according to weight.
P.S. Even though kennel cough presents itself to dogs who are under stress and have compromised their immune system because of the stress, it is contagious- be sure that you lysol your pet's kennels and wash their linens while you are treating them. Good luck!

Please tell me you don't use Lysol. Do you understand what each ingredient does to your lungs as well as your fur baby health? clean with unscented lavender sugar soap, unscented castile soap etc...

Yes three drops from an eye dropper. Worked for my pup.. I did it whenever I filled her bowl up with fresh water; which was morning and night.

It will if you use it at 6% I believe but not 3%. just by adding 3 drops to their water bowl is fine- I do it all the time whenever they're looking sick- dogs, cats, chickens- all. (including myself) ;)
Maple Syrup

My dog was diagnosed last year with kennel coughing, whatever stopped within cough. I knew this was wrong because Kennel Cough is higly contagious, so the experts say. I have three other dogs that lives in the same house and they have never caught it. The vet gave my dog an atibiotic which never worked and a year later she is still couging and still no other dogs in the house coughing.
Tonight I tried 1 tbsp. Of Organic maple syrup only and within 10 minutes her hacking, gagging, coughing stopped. I am going to try the lemon juice and 3% peroxide with the maple syrup if this coughing starts again tomorrow.
I will not spend another 200.00 for bloodwork etc.or antibiotics again. That expensive therapy did nothing for my dog. Just 1 TBSP has done the job for now. Maybe we all will have a quiet night and day tomorrow. I know she is miserable coughing all the time. It's defintely not a contagious disease whatever the cause.

The new 1year old yorkie I'm fostering seems to be exhibiting Kennel Cough symptoms. At day 2, he was having a hacking cough attack approx 10 min after eating (last only a few secons). Seemed to be okay during the day but definitely lethargic like other symptoms noted on this forum. in the evenings, he was prone to more frequent, but smaller hacking fits (which thankfully don't last long for his sake). I didn't want to go the traditional antibiotic route due to his size and unknown history.
After reading about the hydrogen peroxide option (I have the 35% grade), I diluted 3tsps of H2o2 in 8oz of water with a little bit of honey - cut a few small pieces of bread and soaked the bread in a few tsps of the mixture, then mixed the bread with his lunch. I was excited after all of the other reviews on here, but the poor little guy threw up his lunch shortly after eating. :(
I see one of the h202 uses is also an emetic, so perhaps the solution wasn't diluted enough? (Or maybe this mixture is not suitable for small dogs?)
A few hours later, he's been resting most of the day (and will get up for hugs and pets), but will go back to his blanket to rest. He had a few hacking spells but they didn't last long.
Any other suggestions? I'm aware of the pneumonia precautions with KC as well as trachea issues with Yorkies.
Since he travelled far (shelter/kennel in either GA or SC) to NYC, I want to be sure he's taken care of properly (and believe me, he's getting LOADS of TLC and Love :))
Thank you, all.

Three tsp of 35% food grade is way too much. Should have been three drops.

Something must be a typo - 35% HP should NEVER be ingested! HP is caustic. If you get it on your fingers it will make the skin go white. It will turn back to normal in about 10 minutes but you wouldn't want to do that to the insides!!!! 35% food grade HP has to be diluted, 1 part to 11 parts water. And do not take the stuff you get in the brown bottles from the pharmacy/supermarket, that is not for consumption as it has toxic stabilizers in it. A little caution, please! HP is wonderful but one must be careful with doses in this especially. It really is a great thing to know about Hydrogen Peroxide - miraculous!

Thank you, Thank you, Thank you. Yesterday my dog woke up sooo sick. She was coughing and had terrible mucus in her nose and I could tell she was feeling very sick. I gave her the peroxide and honey and truthfully in 5 minutes, she went outside and ran around like the puppy that she is.I know it sounds unbelievable, but I am telling the truth. I mixed a few drops of peroxide and honey and some warm water and poured it down her throat. It is now in her water dish. Thank You !!

Ok we tried the peroxide and honey addition to the water when I had a rescue foster come into our household. I heard her sneeze and knew what was coming. I have my 4 dogs also and was really a bit worried. I added the peroxide and honey daily for a few weeks. My foster only had a mild bout with the kennel cough, my three eldest never got sick. Two had had K.C. before when I got them, one had never ever had it, she and the other two did not get it. BUT my youngest did. Sooo I guess it worked for 3 of mine and not the forth. I still would recommend giving it a try because I only had one get sick.

My Pomeranian, Holly, had kennel cough. WE used the 3% Hydrogen Peroxide, but the cough would just get weaker. We then tried no-dye Benadryl in the the morning and at night. It works great she has a lot of energy during the day and at night she can sleep. We are going to do this remedy for another week so she can get better.

I have a malshi (mix of maltese and shitzu) and he has been having that weird cough like he is chocking on something and then he stops..I dont know if that can be considered kennel cough or not. He doesn't sneeze but i did notice some nasal discharge. Should I just give him the hydrogen peroxide? and just to double check...the hydrogen peroxide has to be 3% or 35%?

Hydrogen peroxide - 3%!
Anything stronger could burn or cause other problems.
