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.

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.

Questions & Answers

10 Customer Questions

I understand I cannot clean ears while using Zymox, but can I use a cotton ball to clean out ‘gunk’ from the ears or should I leave it there?

Answer by Chewy • Nov 02, 2018
When flushing ear canal, it's recommended to clean excess with cotton ball.

Can it be used to treat ear mites?

Answer by Chewy • Nov 23, 2018
Zymox Ear Solution is meant for infected ears. We recommend consulting with a veterinarian to determine which is the best treatment for your pet.

This talks about bacteria, but what about yeast?

Answer by Chewy • Dec 13, 2021
This ear cleanser can help with yeast. However, if it is a yeast infection, it is recommended to use an ear solution.

Does this help dry up water in the ears from swimming, bathing, etc.?

Answer by Chewy • May 30, 2025
This ear cleanser is intended to clean dirty ears, and it is formulated to inhibit bacterial growth. It can help remove excess moisture.

The bottle says not for infected ears. Which I really didn't see until after I purchased. If your cats ears are perfect, I don't know why you'd need a cleaner. Most people clean their pets' ears if there is an issue. A cleaner for healthy ears doesn't really make sense. The cleaner itself leaves a sticky sweet residue and the cats are always licking it off of each other, which Zymox says is perfectly safe, but I'm still not completely fine with. Zymox's other products are much better for ears that tend to have wax build up and prone to ear infections. I was given a bottle with hydrocortisone, which works wonders for yeasty ears. I bought this because it was inexpensive for the volume, but it doesn't suit my needs.

Cat doesn't tolerate

Kitty did not have ear infection nor mites, but ears were always so itchy, she scratched bloody sores into them. After the very first treatment, scratching scaled back to maybe 5% to 10% of what it was, by next day the sores were healing and are now totally healed in one ear and just some little scarring left in the other. This is after just six uses. The other amazing thing is that she tolerates me putting it in. (I do not drip it directly in the ear per the instructions because she's never tolerated medication administered that way. I'm putting it on a cotton round, then combo swabbing the ear and canal whilst ringing the round out.)

Gentle, nonalcoholic rinse for routine cleaning

We apply this gentle rinse with massaging weekly in our GSD's ear canals. After he flings his head, we can wipe out excess and loosened dirt with a cotton pad

We apply this gentle rinse with massaging weekly in our GSD's ear canals. After he flings his head, we can wipe out excess and loosened dirt with a cotton pad. It doesn't contain alcohol, so it's not likely to suddenly sting and hurt if he has an open sore or bite -- which would make it much more difficult to clean or treat his ears in the future.

I have used several different ear cleaners and this one seems to work best both in the dogs reaction to it and the duration of time before they start trying to scratch

My toy poodle gets itchy ears from time to time. And not just an itch here and there. He will itch constantly for days sometimes. I use this stuff and it makes the itching go away. I believe it is an outdoor allergy happening but this works. If he is itching alot and I pick up the bottle, he will come to me cause as much as he doesn't like the feeling of it going into his ear, he knows what comes after. A Fetch Fry, a hug and RELIEF!
