Overview
["This 4 oz Zymox Ear Cleanser is a liquid, unflavored formula labeled for adult dogs of all breed sizes. It's built around three named ingredients, lactoperoxidase, lactoferrin, and lysozyme, and the label describes it as additive-free.", "It's recommended for ear cleaning and maintenance, including use during post-infection management, meaning it's positioned as an upkeep step rather than a stand-alone treatment for a new problem. That makes it a fit for owners keeping ears clean between vet visits or continuing care once a vet has already addressed an issue.", "At $16.99 for 4 oz, it lands in the middle of this category on price, and with roughly 6,000 reviews at a 4.6 star average and about 200 units bought in the past month, it has a long track record within Amazon's dog ear care listings."]

Performance notes
The enzyme trio here, lactoperoxidase, lactoferrin, and lysozyme, is the same active system Zymox uses across its ear care line, positioned to help support a balanced ear environment during regular cleaning rather than to aggressively strip the ear canal. That fits it for upkeep and for the maintenance phase once a vet has already addressed an ear issue, rather than for a first-line response to a new problem.
What buyers say
Roughly 6,000 reviews at a 4.6 star average, with about 200 units bought in the past month, points to a steady base of repeat buyers who use this as an ongoing maintenance cleanser rather than a one-time purchase.
Is this meant to be used on its own for an active ear problem?
It's formulated as a cleaning and maintenance product, including for use once an ear issue has already been addressed by your vet, rather than as a stand-alone product for a new, active problem. If you suspect something is wrong, check with a vet first.
Is this cleanser scented?
No, it's labeled unflavored and additive-free, so there's no added fragrance or flavor in the formula.
Is it suitable for puppies?
The label lists this as an adult formula, so if you have a puppy, it's worth asking your vet whether this cleanser is appropriate before starting regular use.
