The smell was not terrible at first, and that is the part I want to be honest about. Early April 2025, I lifted Wally off the couch and caught something sour in his left ear. Not strong. Sour like a dish towel that sat too long in the sink. I told myself I would keep an eye on it.

Two weeks later it was still there, and he had started scratching at that ear with a back foot whenever he settled on the rug. I read about vinegar and water. I read about a dozen kitchen remedies posted by people certain of themselves. I did none of them. So I called Dr. Reyes and we went in on a Tuesday.

She looked in the ear, said infection, and sent us home with prescription drops for ten days. Then she said the part that mattered more. This will keep coming back, she told me, if the ear never gets cleaned in between. She wrote a name on the back of the visit summary. Virbac EpiOtic, a routine cleanser, not a medicine. Clean it once a week while the ear is healthy, she said, and stop guessing.

Wally is a 4-year-old Cavapoo, 16 pounds, apricot curls, and the long floppy ears that came with the Cavalier half. Those ears hang over the canal like a lid. Air does not move through there. Dr. Reyes said that is half the reason small floppy-eared dogs land in her exam room in the first place. I ordered the Virbac bottle in May 2025 and I have owned it about 18 months now.

Here is what the bottle actually is, because I did not know before I bought it. It is an 8 ounce ear cleanser made by Virbac with veterinary dermatologists, and the label describes it for routine cleansing of sensitive ears in dogs and cats. Neutral pH, sting free, and it is aimed at dogs with allergies, frequent swimmers, and dogs who need their ears kept clean rather than treated. It does not kill an infection. That was the drops' job in April, and it is the vet's job every time.

No ear infection since April 2025. I do not credit the cleanser alone for that, and I will not tell you it treats or cures anything.

EpiOtic Advanced is the routine ear cleanser for healthy ears, not a treatment for a sore one. One 8 ounce bottle lasts me about four months at one cleaning a week.

Our Sunday evening, in detail. After supper I take an old towel into the laundry room, because this is a wet business. The Virbac bottle lives on the shelf above the washer where I cannot miss it. I fill the ear with the solution the way the label says, which is more than I expected the first time I did it. Then I fold the ear over and massage the base of it for about twenty seconds. You can hear it working. Then I stand back and let him shake, and he shakes everything he has got onto the towel, the wall, and once the cabinet door. Last, a cotton ball around the outside of the ear. Never a swab down the canal. That is the one rule I do not bend. Four minutes an ear, start to finish.

We have had no ear infection since April 2025. I want to be careful with that sentence, because I am not a vet and I am not going to write like one. I do not credit the cleanser alone. He is on a food that suits him, Dana keeps the hair out of his ear canals every six weeks, and I put my nose near his ears more often than once a week now. What I can say is that the sour smell does not build up the way it did. If an ear ever came up red, hot to the touch or painful, I would be in Dr. Reyes's office that day and not reaching for a bottle.

Where it falls short. It is messy, and there is no polite way to put that. He shakes it onto the walls and I have wiped the same wall a hundred times. He also does not care for the first few seconds of it, and he backs up when he sees the towel come out, though he stands still once I start. If you want something your dog trots over and asks for, this is not that. It is a job you do on a schedule because the alternative is worse.

People ask me about Zymox. I have never owned it and I have never used it, so I will not pretend otherwise. I have read the label and I have asked Dr. Reyes what she thinks, and my understanding is that it is a different kind of product with a different purpose. Read both labels and decide for your own dog. What I can tell you is why I never switched once I had something that worked and that my vet had named out loud.

What I'd Tell You If We Were Sitting at My Kitchen Table

I would tell you that the smell is the signal and the scratching is the alarm, and that two weeks of waiting is two weeks too long. I would tell you to go to the vet first. Not because I get anything out of saying it, but because an infection needs a diagnosis and a cleanser cannot give you one. Then, once the ear is healthy again, I would tell you to buy one bottle and put it where you will actually see it, the way the Virbac bottle sits on my laundry shelf, and to pick a night. Sunday works for us because Tom has the ballgame on and I am not rushing anybody out the door. Four minutes, one ear at a time, an old towel, a cotton ball, done. I would tell you that one bottle covers about four months of Sundays and that I wish I had started in 2023 instead of waiting for a smell to get loud enough to notice. And I would tell you the other half plainly: if the ears are clean and the dog is comfortable, you can skip all of this. Not every dog needs a shelf of products. Wally needed this one.

Start with the vet. Then start the Sunday habit.

EpiOtic Advanced is the routine cleanser Dr. Reyes named for Wally's floppy ears. One 8 ounce bottle, once a week, about four months of Sundays. Red, swollen, painful or smelly ears are a vet visit, not a bottle.
