One of the most popular remedies in Earth Clinic's pet section is Ted's Hydrogen Peroxide and Borax treatment for mange. In addition to this effective treatment, our readers have also reported that borax is helpful as a rinse to treat other 'itchy skin' problems that their dogs are having.

Borax for Demodectic and Sarcoptic Mange

To date, thousands of people worldwide have used Ted's Mange Treatment on their dogs. Not only is this treatment safe and effective, it is also very inexpensive. The borax and peroxide remedy has also been used by our readers to treat ringworm and similar conditions.

Borax for Yeast Infections

Borax is effective for treating yeast infections because it prevents sugar from reaching the yeast, starving the yeast, or reducing the severity of the problem. A saturated borax solution is made with 1% hydrogen peroxide to use externally to kill the yeast. Ted has said that the saturated borax solution is even more effective if 1/2 teaspoon of manganese chloride and 1/4 teaspoon of zinc acetate is added per liter of water. Dietary changes are also necessary.

Borax Added to Drinking Water

For internal use, a tiny amount of borax, typically a pinch, is added to a dog's drinking water. This is another way that borax helps treat skin conditions and other issues, including ringworm, yeast overgrowth, parasites, and more. See Ted's post below for measurements.

Borax for Fleas

Borax sprinkled on carpets dries out flea eggs so that they can't hatch and perpetuate the flea infestation. Outside areas can also be treated for fleas with a mixture of 4 parts of borax, 1.5 parts of salt, and 1.5 parts of baking soda.

I have a 10 yr old boxer. I put a very small amount of borax in "our" bottled drinking water (He got sick from tap water $177 vet bill). Cheaper to give him bottled water. After 3 months he and I are doing better. So there you have it from two old bachelors. Parts are starting to work better. We don't look at the stairs and then look at each other, we just climb them.

Borax is very good for animals and humans alike in the right dose. It does help arthritis - joint problems. One word of CAUTION! I started taking a very small amount diluted in water ( 1 tbsp per gallon water) I took 1 tsp of water a day. Being 2 years into menopause, no periods, I had a "period from hell". It does affect your hormones. I stopped taking it. Will wait a year and try again.

I have used Borax in my RO water at a rate if 1/8 teaspoon per gallon and also add a pinch of grey salt. In my entire immediate family, there are 19 canines and 5 cats. All of them have been drinking this water for 21 months and we have not had any issues.

In fact, our older dogs seem to move less painfully. Hope this helps :)

You say borax is safe for dogs but everything I am reading on the internet says it very toxic and should seek a vet if ingested. I need a cure for yeast in a 4 year old chocolate lab but I'm afraid to use your suggested rinses of borax. Borax in the drinking water???? Am I missing something or is there a different borax than what is at the grocery store used for cleaning?

Hello Lisa --- google Walter Last

I needed education years ago. That was when I visited EC for the first time. This link has a few more pages of valuable info. Not what is in the media or gov't or what doctors tell you. You are lucky to get to know the truth.

Namaste, Om

Hey Lisa!

You are definitely missing something :-)

Borax has the same toxicity as table salt; take in too much table salt and you will get very sick. Same with water; drinking too much water *will* kill you.

If your dog ingests borax by licking it off it's coat, if it gets *too much* it might get diarrhea. 1/4 teaspoon borax in the drinking water - a common dose for humans and pets alike - may cause stomach upset if you take it all in one go in 8 ounces of water, but in a liter of water taken by a sip here or there throughout the day generally poses no upset.

I use borax both in my laundry - and orally and externally for me and my pets and all with good result.

I just want to make sure the borax is safe for a 5 month old yorkie pup that weighs 4lbs. before I put it in her drinking water or try on her skin with the peroxide to treat demodex?

Replied by Theresa
(Mpls., Mn)

Hey Lac806!

Borax is 100% safe to use on the skin of your puppy. If this were my puppy I would wait on adding borax to the *drinking water* until the mange was cleared to avoid over stressing her - just me.

Be careful of dosage. Dosing a German Shepherd vs a Yorkie is different. Start at lower dosage.

Also, NEVER confuse or use Boric Acid instead of Borax. Two completely different products. Boric acid is toxic.

Do your research!

My pug, Dottie, gets a "good rinse" with Warm Borax solution before she's done with her bath. No one fleas, no itching, And she smells good.

Do not confuse Boric Acid (which is very toxic) to Borax (find on laundry soap isles in Walmart)


Boric acid and Borax are the same thing, BUT boric acid is ground into powder, whereas Borax is more coarse. So it can't be measured the same. Both Borax and Boric Acid are used in eye washes and contact solution. So dangerous ha ha. You would get a lot more boric acid if you tried measuring it the same. Just like you get a stronger cup of coffee, if it is ground into powder. Stick with Borax, and you will know the correct measurements.

Yes it is 20 Mule Team Borax, and is safely used internally when properly diluted. We take 2 tsp. of the following solution daily:

mix 1 teaspoon borax with a quart of water. It's about as toxic as table salt, just use responsibly.

Hey Candice,

I use 1 tsp per liter of water [this is a high dose IMHO] for both my cats and dogs at certain times of the year.

Borax is the only safe element which a very small amount will interact with Fluoride and NEUTRALIZE IT. Why Fluoride is in are drinking water, who knows. Fluoride was NEVER SAFE for human consumption ever..... Read the warning on YOUR tube of fluoride toothpaste. "swallow ONE drop" "call poison control" I use Borax as part of water filtering process. They are adding chemicals in bottled water now. I couldn't find Absopure. and decided I'll just do my own.. and Fluoride free. Recipe on you tube

Small amounts are required in dogs and humans.. many people supplement this daily.. and the laundry borax is very commonly used.. it is a naturally mined mineral.. in large amounts it's an ant killer..huge amount of information online.. very beneficial to arthritis.. very popular

I add water to my dog's food - could I add the borax to this rather than the water bowl? She has several water sources but in her food I know how much she is ingesting each day.


Hi! How much Borax do you add when you bathe your dog?

Replied by Lydia

I've noticed everyone on the internet who says Borax is dangerous is trying to sell something. Also, what could be more dangerous than the poisons in flea and tick control products.

It's actually Boron that is needed in small amounts internally. Boron is in borax but in very small amounts.

HI I see someone asked if safe for cats but no reply; I use it as a cleaner and would really like to know if they walk on it or lick it they will not die!! Please respond..appreciate thank you

Hey Tisha,

Borax is a type of salt. You can bathe your cat in it if you so wish. I use it all the time for bathing my dogs and they splash and my cats have walked through it without harm. I do use Ted's Borax protocol for dogs now and then and so my cats drink the same spiked water as the dogs and myself. If for some reason your cat were to ingest a goodly amount it might get loose stools; licking off the feet here or there should not do that.

Borax Safety

Posted by Mark (Exeter, United Kingdom) on 08/22/2015 12 posts

Hi, I submitted a post that contained emails confirming safty of borax from a supplier named intralabs.

Could you also apply it to the PETS section of borax as little info seems to be in that section except for people thinking its toxic. Thanks, Mark


Below is my email to intralabs and their reply stating the safety of borax, the only toxic effects apply to unborn babies whose mother ingests. The 'powers that be' have left that bit out to make us think toxicity applies to all of us, hence shops removing borax and replacing with borax substitute (which really is toxic!! ). Email intralabs yourselves for reassurance. They are very cheap too. Label warnings of dangers and toxicity are put on Borax by law.


From: mark speed Sent: 24 October 2014 06:26 To: [email protected] Subject: Borax or Borax?

Hi, Im confused about 'Borax' mainly as my nan used to drink small amounts to rid herself from arthritus, also using it as shampoo then rinsing afterwards with citric acid, she fed her plants with it as every living organisms cells require borax! So I dont understand why yr Material Safety Data Sheet says it is toxic ingested and a skin irritant?

She is still alive & free from arthritus and swears by the stuff. When talking with a few oldies at my mums residential care home it became clear that a fair few in their generation used borax on skin and ingested with no problems, I think the borax product was called '20 mule' or similar.

Please could you tell me why yours is so toxic please?? Also...I always understood that borax and boric acid are the same substance apart from one of them has more water molecules than the other, any advice on this lol?

I want to purchase from you but not if you sell a toxic form as im removing all mainstream pollutant chemicals from my home, then just using borax, citris acid, soap flakes, soda crystals, bicarb of soda and white vinegar for everything from hardcore cleaning, laundry, personal hygiene, pet and my shampoo, insecticide etc (the oldies convinced me there is no need for the squillions of products poisoning us everyday just so some fat cat corporate ****rs can rake in the profits at our expense).

Hope you can help me aquire the borax I talk of if you dont supply the safe version, all I can find is a substitute which my gran says is not borax either!!

Thanks in advance Mark

Borax was reclassified 4 years ago as Repro-toxic by the EU which means that it could damage fertilitiy or an unborn child if eaten.

Borax is not toxic to your general health (other than that just stated) and is actually less toxic than table salt.

This is the reason why your relative is quite well and not ill. 20 mule team borax is the same as the borax we sell, the only difference is that it's not classed as repro-toxic by US law but is by EU law.

20 mule team is a brand of borax, it's all the same.

Just a note on the dosage of Borax added to the drinking water. Ted has posted that the size of the dog doesn't matter because of the amount of water intake but has specified 1/8 tsp per liter for females and 1/4 tsp per liter for males. This goes for human as well.

Hi, I'm just wondering if borax can be used to tackle blood parasites caused by ticks? My dog is presently on IV fighting for her life after contracting the E. Canis parasite from a tick. It wasn't picked up in the initial blood test they did, now it's in the critical advanced stages. She is lame and her body has developed large lumps where the parasites are literally eating her alive. The doxycylin is yet to make any improvement, any chance I could try borax?..Or any other ideas? Many thanks.

For tick born bacteria, I mixed liquid garlic extract, apple cider vinager and colloidal silver (no specific amounts) to kill the bacteria after my senior dog showed signs of dementia and slight paralysis. I found a tick on him and after removal, I continued to give the colloidal mixture every hour and within hours, he showed tremendous improvement! I have used this three times in four yesrs. For worms, I add Diatomaceous Earth, Food Grade to his food.

Borax Demodectic Mange Remedy for Skin Allergies

Any fears I had about Borax injuring my dog are eliminated after using this miracle treatment!

My 4.5 yr old Old English Sheepdog, Bentley, had been cranky and full of itchy skin since we got him at 9wks old. He's had multiple vet visits, being prescribed antibiotics and antibiotic ointment, and skin scrapings with no relief. His resting respirations would be very rapid and he was very aggressive and annoyed. He hated me grooming him and would require a muzzle, though I tried to be easy, any brush stroke or clipper pass would be uncomfortable for him. I had heard BORAX was bad for you and didn't want to further injure my dog, BUT THIS SOLUTION HAS CHANGED HIM!

He now after 2 treatments has a slower resting respiration rate (not laying in constant torture of being bit all the time, totally brushable fur—with a fine tooth comb—without a muzzle (never been done before- OBVIOUS SKIN HEALING! )

I'm sorry it took so long to find this remedy for my poor miserable doggy!
