What Ciccio Taught Me About Looking Beyond the Label
By Kate Beard, Certified Canine Nutritionist & Founder of The Barkery
If you've followed me for a while, you'll know that life with Ciccio is rarely boring.
He's my beautiful rescue dog, but over the years he's kept me on my toes with recurring ear infections, yeast overgrowth in his ears, itchy skin and the occasional digestive upset. We'd treat a flare-up, everything would settle down for a while… and then, a few months later, we'd find ourselves back at the vet asking the same questions all over again.
At one appointment, my veterinarian suggested something I hadn't seriously considered before.
"Why don't we try a grain-free food for a while and see if it helps?"
It sounded simple enough.
Switch the kibble.
Problem solved.
But if you know me, you'll know I rarely stop at the first answer. The vet described that I should try choosing a new ‘grain free’ dog food. Give it 2 months time and see if the flare ups continue. If yes, he may be allergic to the protein source, so try a different food. Uhhh, as the mom of 3 kids with the attention span of a caffeinated squirrel I knew my limitations, and was not optimistic that I could keep track of Ciccio’s symptoms.
But more than anything, I wanted to understand why. Were grains really the problem? Was grain-free genuinely healthier? Or had clever marketing convinced us to fear an ingredient that most dogs tolerate perfectly well? I really didn’t feel like such a blind hope was the best strategy for us.
So I started reading.
Research papers. Veterinary articles. Nutrition textbooks. Ingredient labels.
The deeper I went, the more I realised there wasn't a simple answer.
At the same time, I made another decision—one that, looking back, I believe had an even bigger impact than simply changing his kibble.
Instead of expecting one food to fix everything, I started looking at Ciccio's diet as a whole. (Read why dietary variety is so important for your dog's microbiome.)
I cut his kibble portion roughly in half and began building the rest of his bowl with fresh, whole foods. Most days that means adding vegetables and fruit, then rotating a small source of protein depending on what's already in my fridge—a hard-boiled egg, a spoonful of Greek yogurt, an espresso cup of kefir, sardines packed in water or a little tuna.
Nothing complicated.
Nothing expensive.
Nothing Instagram-worthy.
Just real food, more variety and a consistent focus on supporting his gut health.
That, perhaps more than anything else, changed the way I think about dog nutrition.
Because here's what I've learned:
Health is rarely transformed by one magical ingredient.
And it's rarely destroyed by one single ingredient either.
It's almost always the result of many small choices made consistently over time.
So... What Does "Grain-Free" Actually Mean?
One of the biggest surprises during my research was discovering how many people misunderstand the term grain-free.
Grain-free simply means the recipe doesn't contain grains such as wheat, corn, rice, oats or barley.
It doesn't mean the food is lower in carbohydrates.
It doesn't necessarily mean it's higher in meat.
And it certainly doesn't guarantee it's healthier.
Those grains are usually replaced by other carbohydrate sources like peas, lentils, chickpeas, potatoes, sweet potatoes or tapioca.
In other words, the carbohydrates haven't disappeared—they've simply changed.
That's why I always encourage people to look beyond the words printed on the front of the bag.
The ingredient list tells a much more interesting story.
Not All Grains Are Created Equal
One thing that frustrates me is seeing all grains grouped together as though they're nutritionally identical.
They're not.
Just like vegetables aren't all the same, neither are grains.
Oats
Oats are one of my favourite ingredients when they're used well. They're naturally rich in soluble fibre, particularly beta-glucans, which can help support a healthy gut microbiome. They're also highly digestible for many dogs and provide slow-release energy.
Brown Rice
Brown rice is often recommended for dogs with sensitive stomachs because it's gentle, digestible and provides fibre along with several important vitamins and minerals. It's a wholesome ingredient that has earned its place in many quality diets.
Barley
Barley is another excellent whole grain. It's high in fibre, contains valuable antioxidants and has a relatively low glycaemic index compared with more refined grains. It can also contribute to better digestive health by feeding beneficial gut bacteria.
Corn
Poor corn.
It may be one of the most misunderstood ingredients in pet food.
When properly processed, corn provides carbohydrates, essential fatty acids, antioxidants such as lutein, and important vitamins. The problem isn't corn itself—it's assuming that because it's inexpensive, it must automatically be bad.
Like every ingredient, quality and formulation matter far more than reputation.
Wheat
Wheat is probably the grain that receives the most criticism.
While some dogs genuinely don't tolerate wheat well, many others digest it perfectly without issue. Whole wheat can contribute fibre, protein and B vitamins to a balanced diet.
It's important to remember that a true sensitivity to wheat is very different from assuming every dog should avoid it.
So Should You Feed Grain-Free?
The honest answer is…
Maybe.
If your veterinarian recommends trialling a grain-free diet because of persistent skin issues, digestive concerns or a suspected sensitivity, it's certainly worth exploring.
That's exactly what we did with Ciccio.
But here's where I think many of us—including me, at first—can fall into a trap.
It's tempting to give all the credit to one change.
If your dog's ears improve after switching food, was it because the grains disappeared?
Maybe.
Or perhaps the new food contained a better protein source.
Perhaps it used higher-quality ingredients overall.
Perhaps you also started adding fresh foods, improving gut health and paying closer attention to your dog's nutrition—as I did.
Real life is messy.
Nutrition isn't a laboratory.
And dogs don't live inside controlled scientific studies.
That's why I think it's important to stay curious instead of becoming attached to one explanation.
The Marketing Trap
The pet food industry is very good at convincing us that one label tells us everything we need to know.
Grain-free.
Gluten-free.
Corn-free.
Soy-free.
Those words sound reassuring.
But they don't automatically tell us whether the food itself is well made.
I've seen grain-free foods where the first several ingredients are different forms of potatoes and legumes.
I've also seen recipes containing wholesome oats or brown rice alongside excellent-quality protein and thoughtfully selected whole-food ingredients.
One isn't automatically better simply because of the label.
This is why I always turn the bag over.
The front is marketing.
The back is information.
What I Look For Instead
Rather than asking whether a food contains grains, I ask a different set of questions.
- Is there a clearly named protein source?
- Are the ingredients recognisable?
- Are whole foods included where possible?
- Does the recipe contain a variety of nutrient-rich ingredients?
- Are several refined starches replacing one another?
- Does this look like a thoughtfully balanced recipe rather than a collection of trendy buzzwords?
One trick worth knowing is something called ingredient splitting.
Manufacturers can divide similar ingredients into separate components—such as pea protein, pea fibre and pea starch—so each appears lower on the ingredient list, even though together they may make up a significant portion of the recipe.
It's another reminder that reading beyond the headline is always worthwhile.
The Bigger Lesson Ciccio Taught Me
Looking back, I honestly can't tell you that grain-free food "fixed" Ciccio's ears.
I don't think that would be fair—or truthful.
What I can say is that around the same time we trialled a grain-free diet, I also committed to improving his nutrition in every way I reasonably could.
I added fresh vegetables.
Superfoods at every meal became non-negotiable.
I rotated whole-food protein sources.
I supported his gut microbiome.
I paid more attention to ingredient quality than clever packaging.
Most importantly, I stayed consistent.
That consistency mattered far more than chasing the next miracle ingredient.
Because that's the slightly frustrating truth about health.
Whether we're talking about dogs or ourselves, there is rarely one magic bullet waiting to solve everything overnight.
Likewise, there is rarely one "bad apple" responsible for every problem.
Health is built through countless small decisions repeated day after day.
A nutritious diet.
Regular exercise.
A healthy body weight.
Mental enrichment.
Good veterinary care.
Fresh water.
Quality sleep.
Less processed food.
A little more variety.
None of these things are dramatic on their own.
Together, they're incredibly powerful.
My Personal Conclusion
If there's one thing Ciccio has taught me, it's that keeping an open mind is one of the most valuable tools we have as dog owners.
Sometimes we become so focused on finding the one ingredient to eliminate that we forget to look at the bigger picture.
For me, improving Ciccio's health wasn't about declaring grains "good" or "bad."
It was about becoming more intentional.
Reading ingredient lists instead of marketing slogans.
Adding fresh foods wherever I could.
Supporting his gut health consistently.
Paying attention to his body instead of the latest trend.
Will grain-free be the right choice for some dogs?
Absolutely.
Will it be necessary for every dog?
Probably not.
And that's okay.
The goal isn't to find the perfect bag of kibble.
The goal is to build the healthiest bowl you can, one thoughtful choice at a time.
Because good health isn't created by one miracle ingredient.
It's created by consistency.
By staying curious.
By keeping an open mind.
And by remembering that the little things we do every single day almost always matter more than the dramatic changes we make once in a while.
That's the philosophy I try to follow with Ciccio.
And it's the same philosophy that guides everything we do here at The Barkery.
