🐶 Why Does My Dog Keep Getting Ear Infections?
Third round of drops this year. Same ear.
Here's why. And here's how to actually stop it happening again.
You have cleaned it properly, every time.
You have dried it after every walk in the rain.
You have switched to the "sensitive" food because the bag told you to.
You have added the apple cider vinegar rinse someone recommended in a Facebook group.
You have added, and added, and added.
None of it touched the real cause. Because none of it was ever aimed at the real cause.
Here is what nobody tells you at the vet.
Nobody tells you at the pet shop either...
And no stupid rating site will ever tell you.
A recurring ear infection is very rarely an ear problem.
The ear is just where you finally see it, not where it started.
Picture a greenhouse. Warm, sealed in, humid. Yeast and bacteria will always want to live somewhere like that, that part is completely normal biology.
What decides whether they behave themselves or take over is whether your dog's body has what it needs to keep them in check. That is nutrition. Not luck, not "just one of those ears," not a breed thing.
We have tracked this exact pattern since 2004. Dogs stuck in the infection, drops, infection again cycle almost always share the same handful of nutrient gaps underneath it, regardless of breed or age.
Dogs don't digest ingredients, they digest nutrients. That's the whole point, and it's the one thing almost nobody selling you a bag of food or a bucket of treats ever actually explains.
There are 49 of these nutrients your dog needs. Not one, not ten, forty nine. Ignored, or completely misunderstood, by the vast majority of owners, through absolutely no fault of their own.
Every single one of those 49 has an upper limit and a lower limit. A genuinely healthy dog needs each one sitting somewhere inside that range, not below it, not above it. Also ignored by the average owner, because marketing is far too busy distracting them, pushing the next best thing, getting louder, more exaggerated, wrestling biology to the ground and shoving it behind the curtain.
Because biology, and the actual solution, means less money for them. Highly likely bankruptcy if the truth ever really landed. So instead they look for weak minds, and they find them, with alarming volume and even more alarming accuracy.
Here is the timeline nobody warns you about either. This pattern usually took months, sometimes years, of small gaps quietly stacking up to build. Properly undoing it takes real time too, weeks, sometimes months, not one course of drops. Start today and that clock starts today. Ignore it and the cycle just keeps running, and every cycle is a genuinely uncomfortable few days for your dog, not a minor inconvenience you're managing around.
To understand why, you need to understand two completely different vitamin systems, plus a set of minerals that behave like one of them rather than the other.
Vitamin C and the B vitamins are water soluble. Your dog needs the B group topped up daily, they are not stored for later use, any excess simply gets urinated straight out. Vitamin C works differently again, your dog actually manufactures his own, so it is one of the rare nutrients that genuinely doesn't need topping up from outside.
Vitamins A, D, E and K are fat soluble, and they behave nothing like the water soluble group. Minerals like calcium, phosphorus, zinc, copper, iodine and selenium follow the same rules as this fat soluble group. All of them get laid down in fat, bone, liver and other organ tissue. They build up slowly. They clear slowly.
That slow storage is exactly why they matter so much here, and exactly why they can quietly become the cause rather than the cure. Every source adds to what's already stored, and almost nobody is keeping count of the total.
Not only does that overload become genuinely toxic in the wrong amounts. Long before it reaches that point, it is already the start of a low level discomfort that will not resolve on its own. It sits there, quietly, flaring the same ear again and again, until somebody actually addresses the total picture rather than the ear itself.
Zinc earns a specific mention here. It plays a direct role in immune response and skin integrity, both of which decide how well your dog's ears cope with the yeast and bacteria that live there regardless. Get zinc wrong in either direction, too little or too much, and ears are frequently one of the very first places it shows.
Here is where most owners get caught out completely, through absolutely no fault of their own.
You are being marketed at constantly. Some good information, but mostly, really bad information...
TikTok shops. Facebook groups full of confident "experts." Your mate at the park with strong opinions. The market stallholder selling treats out of a bucket. Your local pet shop. The high street chains too. Every single one of them pushing the next add on, and every single one of them reaching for the same two words, packed with.
Here's the bit worth understanding about all of them, and this genuinely isn't a dig. They can't afford to give you advice that's purely in your dog's interest. They have rent, energy bills, staff, their own cost of living to cover, same as anyone. That reality means the incentive is always to sell you the next thing, never to tell you your dog already has enough of something. It's not malicious. It's just not the same job as managing your dog's actual numbers.
Packed with vitamin A. Packed with zinc. Packed with goodness. Nobody ever asks packed with, on top of what exactly. That's the whole problem in three words.
(This is precisely where a nutritionist earns their keep, someone who can actually give you real numbers, grounded in NRC guidance. NRC stands for the National Research Council, the body behind the peer reviewed nutrient targets used across canine nutrition, built on decades of published science rather than a bag's marketing copy.)
(In practice that starts with a base food genuinely providing all 49 required nutrients in the correct ranges. From there you need to know what everything added on top actually does to those numbers. Four or five innocent looking chicken feet, does that tip your dog's calcium too high? Simple question. Most owners have no way of answering it. You should.)
Fed blindly, which is exactly what nearly everyone is doing without realising it, these nutrients stop helping and start working against your dog. They become the danger, not the fix.
The answer is almost never add more. More is simply more for organs that are already working overtime to process it.
More for the kidneys, whose job is to filter the bloodstream and clear out exactly this kind of excess, quietly, nutrient by nutrient, day after day, without ever once being asked if that's manageable.
More for the liver, which processes and stores a huge share of what those fat soluble vitamins and minerals bring in, and simply has to work harder the more it's handed.
More strain on the heart too, pumping a system that is carrying more than it should ever have to carry.
The list of jobs a dog's body quietly gets on with, without complaint, without a single day off, would look like modern day slavery if we were ever talking about a person.
Nobody tells you that either.
Because they build up in tissue, bone and organs rather than passing straight through, this is where the majority of the recurring illnesses we see genuinely start.
Whether a nutrient is running too low, or too high from months of well meaning extras, the ear is very often one of the first places it shows, right alongside the skin.
We hear from somewhere between 120 and 135 people a day describing exactly this. Roughly half of them mention skin, coat or ear symptoms as part of a wider pattern, not as one isolated issue.
That volume is exactly why we're confident about what actually resolves it. We see it fixed too often for it to be coincidence. Most dogs with recurring ear infections are not simply "prone to them." They are underfed in the nutrients that would protect those ears, or more often, overloaded on others entirely, or both at once.
It is very rarely one dramatic missing nutrient. It is usually several sitting slightly wrong at the same time, some low, some high, compounding on each other.
That is a genuinely different problem to solve than "he just gets ear infections."
Once you actually have the real numbers, and once you find a food that genuinely delivers them properly, the whole thing stops feeling like guesswork. Clarity arrives.

This is exactly why we built our nutrient tracking system the way we did. Dogs don't digest ingredients, they digest nutrients, and once that distinction actually clicks, recurring ear infections stop being a mystery and start being a nutrient equation you can genuinely solve.
Watch what's happening in the treat tin too, more than most owners ever realise. A dog eating a beautifully balanced main diet can still tip out of balance through treats alone, particularly anything heavy in omega 6 without omega 3 to match it. That imbalance actively drives inflammation, and inflammation is precisely what keeps an ear canal irritated enough to flare up again and again.
So next time it happens, before you book vet visit number four, ask a different question entirely. Not "what's wrong with his ear" but "what's actually going into him."
You might be thinking it right now. This clown keeps banging on about the same solution, whatever the blog title says.
You're right. We do. Here's exactly why...
Marketing needs you living in chaos. Different subject every day, different product every week, always the next best thing, always spending on hope, always waiting to see if something reacts. Thrashing about like a ship in a storm expecting calm, wanting heaven while quietly opening the doors to hell.
None of that chaos touches the bit that actually matters. Your dog's organs don't change because a new trend turned up. And the NRC data behind what those organs actually need doesn't shift an inch either, whatever symptom happens to be on the title of the blog you're reading.
Same organs. Same data. Same answer. That's why it repeats.
Please comment if you have enjoyed this blog, especially if you read it weeks or months ago and are already seeing changes in your dog, which you should. Or contact us through the contact us form. We get 120 to 135 plus of these enquiries a day, around half mentioning skin, coat or ear problems among other red flags, and we are confident this works simply because there are far too many dogs getting fixed to explain away.

Beyond that link you will find more than just dog food. Our food provides the 49 nutrients your dog needs, all in the right ranges.
There is also a free one to one nutritional page, which helps you track weight, hugely important, using guidance the NRC set out in their own peer reviewed, four hundred page body of data. There is nothing else quite like it. It is what elite dog owners do.
You can also get access to a free spreadsheet. It will show you all the NRC numbers behind the food, and it lets you add in over 40+ different treats, with quantities, so you can see exactly what is safe as those numbers change. There is nothing like it anywhere in the United Kingdom.
If you are serious about fixing this, if you want to be your own dog's personal nutritionist, click that link and watch the videos. It is a long read.
But it will improve your dog's chances of a longer, and definitely healthier, life.
