Because Zymox formulas are made with 100% naturally derived enzymes from dairy, they are safe for anytime use, both for immediate soothing relief and to prevent infections. The powerful enzymes work to eliminate problem single-celled organisms such as bacteria, fungi and yeast, while leaving healthy cells untouched. This means no irritations for your pal!

Enzyme-Based and Antibiotic-Free
Zymox products use a patented, gentle formulation that combines three potent, naturally occurring enzymes—lactoperoxidase, lysozyme and lactoferrin—that are sourced from milk products. These enzymes are proven to work together to eliminate the source of infection on your pet, without any toxins or antibiotics that can irritate or cause antibiotic resistance.
About ZYMOX
Zymox was founded in 1998 by Pamela Bosco, who sought to change the way that people treated and managed ear, oral and skin infections with a safer alternative to antibiotics. Enlisting the help of her brother—a scientist that developed the enzyme technology in Biotene—Bosco formulated a powerful enzyme-based solution to help treat infections in dogs, cats and horses with no toxins, chemicals or antibiotics. Committed to keeping all four-legged pals healthy, they offer USA-made and sourced products to treat, soothe and protect against bacterial and fungal infections gently and 100% naturally.

These products seem to always do the job
By Bassetmom on Sep 6, 2020
I have used Zymox in the past, purchased first from my vet a number of years ago. If I purchase something else, I just go right back to this brand because they work so much better. I decided to try this formulation without the hydrocortisone because my dog's ears aren't that bad so better not to overuse the hydrocort. I have a basset hound, they are prone to ear difficulties if you don't keep an eye on them. Long ears, loose skin, enough said. If you know your dog is headed in the direction of a bad ear episode, these Zymox products can keep it from becoming overblown. If you are past that point, they do wonders to clear the issue up.

I like it, it works really well

Seems to be working pretty well
By airdose91 on Jul 16, 2020
We had to switch to this product for our dogs ear infections. The other stuff we used straight from the vet cause him to go mostly deaf. This product definitely takes longer to clear up the problem but his ear is looking significantly better. We have a few more days of use before it should be 100% cleared up. Is a smaller bottle than what I expected but goes a long way.

Great product
By KarenJ on May 3, 2020
I first learned about this product from my holistic vet over 10 years ago. My dog had been suffering from chronic ear infections. Oral antibiotics only made her sick (I am not a fan anyway) and topical ones just weren't doing the trick (plus they mess with the natural flora in the ear. This product did the trick and my dog went without an ear issue for over 8 years. Recently, I had a dog in my care that moved from scratching his right ear to scratching both ears and shaking his head a LOT - clear indication of ear issue. I had been trying to treat with colloidal silver in the beginning, but did not catch this in time to nip it in the bud. 10 days on this product and a f/up check to the I first learned about this product from my holistic vet over 10 years ago.

Also, if there is any possibility of a ruptured ear drum, PLEASE see a vet first as ANY treatment introduced into the ear canal in the presence of a ruptured ear drum can lead to BIG BIG problems. … more
