Why Food Isn’t Always the Enemy — and How to Spot the Difference
Introduction: When “Allergies” Aren’t Allergies
If your dog licks their paws, scratches constantly, or battles ear infections, you might hear:
“It’s food allergies.”
But here’s the truth: most dogs don’t have true food allergies.
What they have are intolerances — and the difference matters more than you think.
Because when you mislabel the problem, you miss the solution.
Allergy vs. Intolerance: What’s the Difference?
Food Allergies (Rare)
Caused by an immune system reaction.
The body mistakes a protein (like chicken or beef) as an “invader.”
Triggers an immediate or strong response — swelling, hives, vomiting, or severe itching.
True allergies are uncommon (less than 10% of canine cases).
Food Intolerances (Common)
Caused by poor digestion or gut imbalance.
The body struggles to break down certain proteins or additives.
Shows up as paw licking, itchy skin, soft stool, smelly ears.
Not life-threatening, but chronic and frustrating.
👉 Put simply: allergies are immune-based, intolerances are digestion-based.
Why the Confusion?
Symptom overlap. Both can look like itching, licking, or digestive issues.
Convenient labels. It’s easier (and faster) for a vet to call it “allergies.”
Marketing. “Hypoallergenic kibble” sells bags — but doesn’t heal the gut.
How Kibble Makes Both Worse
Even if your dog reacts to one protein, kibble isn’t the fix. Why?
High starch = feeds yeast and inflammation.
Additives and preservatives = irritate digestion.
Limited, processed proteins = harder to digest than fresh ones.
Kibble doesn’t solve allergies or intolerances — it fuels them.
The Role of the Gut
Most “allergy” symptoms actually start in the gut. When the microbiome is unbalanced (see: Gut Health and the Microbiome), the gut lining weakens.
This “leaky gut” lets undigested proteins slip through, triggering reactions. Fix the gut, and many “allergies” fade away.
My Story: What I Saw With Smitten
When I switched Smitten off kibble to save his life, I noticed something else: his itchy paws and ear issues improved too.
It wasn’t a “new miracle food.” It was removing kibble, healing the gut, and respecting his biology as a carnivore.
Marley and Dreamer never had the chance. But Smitten showed me that what looks like an allergy can often be an intolerance made worse by kibble.
What Paw Parents Should Watch For
You don’t need to run expensive tests right away. Start by noticing patterns:
Does itching flare after certain proteins?
Does stool change with new treats?
Do symptoms improve when fresh toppers are added?
Observation is your most powerful tool.
The Danger of the “One Protein Fix”
Many Paw Parents turn to “limited ingredient diets” or “novel proteins.” These might help short term — but they don’t address the underlying problem: gut imbalance.
That’s why some dogs bounce from chicken to lamb to salmon to kangaroo, never finding lasting relief.

Conclusion: The First Step Isn’t Elimination — It’s Education
If your dog is itching, scratching, or reacting, don’t panic. And don’t assume the only answer is to eliminate proteins endlessly.
The first step is understanding the difference between allergies and intolerances. The second is supporting the gut and feeding food your dog was designed to digest.
Because when you do that, symptoms don’t just get masked — they get better.
Love them. Nourish them. Respect their nature.
