About ZYMOX Enzymes for Healthy Ears and Skin

Antimicrobial and Antifungal Care

ZYMOX empowers pet parents with patented formulations of natural enzymes to help treat chronic infections in dogs, cats and horses. Their products are formulated to be safe to use on any age pet. ZYMOX packs a potent antimicrobial punch that targets the source of infections—bacteria and fungus(including yeast) to provide therapeutic relief, care, protection and prevention, without any antibiotics or harsh chemicals. Proudly made in the USA and endorsed by TICA (The International Cat Association).

Committed to Healthy Ears, Skin and Coat, and Smiles

To ensure overall health from snout to tail on all four-legged pals, Zymox has developed products that are specially formulated for all the areas that commonly need infection relief, like the ears, teeth and gums, and skin and coat.

Ear Care Solutions

Effective, non-toxic solutions with special enzymes and mild cleansers to keep ears clean and fresh, and combat microbes that can cause ear infections.

Oral Care Solutions

Brushless solutions with unique enzymes to dissolve plaque and prevent its buildup, boost natural "good bacteria," and protect against gum disease to keep kitty and doggy smiles healthy.

Skin and Coat Health

Topical sprays and shampoos for dogs, cats and horses that form a powerful protective barrier against minor skin inflammations from bacteria and fungi, while cleaning and conditioning the coat—with some formulas utilizing hydrocortisone.

100% Safe, Gentle and Easy

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.


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.

Questions & Answers

15 Customer Questions

What is the difference between this product and the regular Zymox Ear Cleanser?
Answer by ChewyNov 09, 2017
Zymox Veterinary Strength Dog & Cat Ear Cleanser contains Coco-Glucoside while Zymox Ear Cleanser for Dogs & Cats contains Sodium Lauryl Sarcosinate.

Can I use this before use with the Zymox Plus or the original zymox Otic enzymatic solution? Will it affect the way the other products work?
Answer by ChewyDec 11, 2019
Zymox Ear Cleanser is the only ear cleaner recommended for use with Zymox Otic Enzymatic Solution because it will not interfere with the activity of the Zymox Three Point Enzyme System.

My Vet recommended I purchase an ear wash with a drying agent for my Pug. Does this have that drying agent?
Answer by ChewySep 14, 2019
This cleanser does not contain drying agents.

Is this product safe to use if my cat has an open cut on the outer edge of his ear?
Answer by ChewyJan 02, 2019
While this product contains no harsh chemicals, added artificial cleansers or other irritants and is safe for use on even the most sensitive of ears, it's not advised to use on irritated ears. We recommend avoiding the cut if possible.

Great Product!

My older shiba had a bad ear infection and my vet prescribed another med along with the ear wash. As the infection cleared, she requested we discontinue the med, but continue with the ear wash. Very happy my pup is feeling much better and the infection continues to clear. YEA!

Finally she stopped scratching her ear.

My Siberian Husky had been scratching her ear for a month, even after a visit to her Vet Office, a course of ear drops to cure her yeast infection and another brand of ear cleaner. Needless to say she runs away from me when she sees me approaching with a bottle and cotton balls. The first application of Zymox she gave me the usual reaction of trying to hide under the couch (she's too large), burying her head in a chair cushion ( I found her) and scooting across the rug on her left ear (I laughed) . I was able to use the Zymox as directed, much to her disgust, and after a gentle massage of both ears, she shook her head and shared some of the Zymox with me, although not in my ears. BUT, she stopped scratching her left ear and didn't start fussing with her right ear. Now she lets me use the Zymox on a regular basis and her ears both look clean and the fur in her left ear she had scratched off is growing back as clean and white as her right ear.

Zymox ear cleaner

Seems to work about the same as some other products I have used on my dogs ears. They look clean and smell better after using.

Ear Cleanser

Leaves a very sticky residue on the fir and hands. The stuff I got from the vet wasn't sticky at all. So if it runs out of the ear use a wet cloth to wipe down your hand and the fir of the dog.

Works amazingly

My dog Lily has small ears that seem to get dirty and infected alot. The Vet recommended this to help with her ears and voila no more head shaking or sore ears.

Goopy Ooky Ears

Used it one time and it totally cleaned all the goop out of his ear. He is feeling much better but I still use the Zymox drops daily until he is completely free of the ick.

Works for our Vizsla and Boxer

We live on a lake and our dogs are always swimming in it and their ears get stinky so with the advice of our vet we tried this. It’s easy to use and it stops their ears from being stinky. We don’t have to use it every time they get a bath just every so often.

Worked wonders!

My pitty Odin needed this ear cleaner like no one’s business after a day at the lake and an ear infection that followed. Super easy, works great, and provided the relief he badly needed!

I need a “cat burrito bag”

Product works well IF I can get it in Tucker’s ears. He’s like wrestling with a greased pig. LOL I’m going to get out the sewing machine & make a padded “cat sack” for him. Weird, but he stays still when the vet cleans his ears!
