Dog Allergies
What’s Causing Your Dog’s Itchy Skin
If your dog is constantly licking, chewing, or scratching— you understand the misery.
It’s one of the most common concerns I hear from pet parents. Whether the symptoms seem seasonal or constant, the label “allergies” is often thrown around. But here’s the truth:
Not all itchy skin is caused by true allergies.
And the real root might be hiding in your dog’s gut, food bowl, or detox pathways.
Let’s break it down—what allergies are, how they differ from intolerances, and what might be making your dog miserable.
Allergies vs. Intolerances in Dogs
These terms get used interchangeably—but they mean very different things in the body.
Dog Allergies
An allergy is an immune system reaction. The body sees something harmless (like pollen or chicken) as a threat and overreacts with inflammation. This can involve histamine release and can show up on the skin, in the gut, or even behaviorally.
Often involve the skin (itching, swelling, hives, hot spots)
May include chronic ear issues or respiratory reactions
Typically appear suddenly or seasonally
Dog Intolerances
An intolerance is typically a digestive issue—where the body lacks the ability to properly break down or absorb a certain food, supplement, or additive.
Often shows up as loose stools, gurgly stomach, or gas
May trigger skin flare-ups secondarily (from gut inflammation)
Symptoms are dose-dependent and may be more subtle
Often related to food sensitivities, poor-quality ingredients, or synthetic nutrients
Why the Confusion Happens
Many dogs with food intolerances show the same red, itchy skin or inflamed ears we associate with allergies. That’s because the gut is inflamed—and when the gut is leaky, the immune system is always on high alert.
So what may look like a seasonal allergy could actually be a food response... or even a reaction to chemical exposure.
That’s why we don’t just chase symptoms—we look for root causes.
Common Triggers: Compared & Explained
1. Seasonal Allergies (Pollen, Mold, Grasses)
Timing: Often show up in spring or fall, but can occur year-round in some climates
Symptoms: Itchy paws, watery eyes, sneezing, red belly or chest
Connection: Linked to histamine response; worse after outdoor exposure
Support Approach: Reduce histamine load through food, herbs, homeopathy, and support detox and lymph flow

2. Food Intolerances or Sensitivities
Timing: Can be year-round; symptoms often worsen over time
Symptoms: Itchy skin, inflamed ears, loose stools, chronic gas, belly discomfort
Connection: Often related to protein type, grain fillers, additives, or poor digestion
Support Approach: Use an elimination diet, gut healing protocol, digestive enzymes, and avoid synthetic additives
3. Environmental Allergies (Indoor & Outdoor)
Triggers: Dust mites, cleaning products, mold, yard chemicals, flea meds
Symptoms: Itchy skin, redness on contact points (paws, belly), chronic sneezing or coughing
Connection: Often overlooked but common; worsened by a burdened detox system
Support Approach: Reduce toxin exposure, switch to non-toxic products, support detox organs, and consider Raindrop for immune balance
The Role of the Gut, Liver & Lymph
No matter the trigger, all roads eventually lead to the gut and immune system.
If the gut is leaky or inflamed, your dog’s immune system may react to nearly everything. And if the liver can’t keep up with the toxins and waste, the skin becomes the backup detox organ—which is why so many dogs with allergy symptoms also have chronic skin issues.
That’s why we focus on:
Binders to mop up waste
Mineral balancing
Detox drainage support
Essential oil protocols like Raindrop
Homeopathy or herbs to calm inflammation naturally
What About Yeast?
Yeast is a common secondary issue in dogs with itchy skin—especially those on repeated rounds of antibiotics, steroids, or processed food.
You might notice:
A cheesy or stinky odor
Greasy, flaky skin
Blackened skin or redness between toes
Excessive licking of paws or groin
Yeast thrives when the gut is out of balance and sugar/starch intake is high. It’s not just a skin issue—it’s a microbiome imbalance.
Is It Really As Simple As a Probiotic or a Protein Change?
A lot of well-meaning advice online will tell you to "just try a new protein" or "add a probiotic" if your dog has allergy symptoms. And while those can absolutely help—in some cases—they’re rarely the full solution.
Here’s why that one-size-fits-all approach often fails:
You can rotate proteins, but if your dog’s gut is inflamed or leaky, even novel proteins may trigger reactions.
You can add probiotics, but if your dog’s liver is congested or the microbiome is out of balance, those beneficial bacteria may never survive long enough to help. If your dog cannot tolerate a probiotic - it’s a big clue to gut health issues.
You can give supplements, but if they’re synthetic or poorly absorbed, they may do more harm than good.
So while yes—a probiotic and a food change might be part of the picture—what your dog needs most is a strategy tailored to what’s actually going on in their body.
Let’s Break Down Some of the Most Common Supplements Used for “Dog Allergies”
Probiotics
Often the first thing people try—and sometimes it helps!
The right strain and form matters. Soil-based or spore-forming probiotics tend to do better in inflamed guts.
If yeast is present, probiotics alone may not be enough. You may need binders or antifungal herbs to create space for healing.
Omega-3 Fatty Acids
Can be helpful to cool inflammation—but not all omega supplements are equal.
Dogs need the right balance of EPA/DHA from quality sources (not just fish oil off the shelf).
Oxidized oils can worsen inflammation, so freshness matters. (We prefer certain trusted brands—see affiliate list.)
Digestive Enzymes
Help break down proteins and fats, reducing the burden on the gut.
Especially useful if your dog shows food sensitivity symptoms but still struggles with nutrient absorption.
Enzymes also support pancreatic function and may reduce bloat or gas.
Colostrum
Naturally rich in immune-supporting factors
Can help modulate the immune system when symptoms suggest chronic overreaction
Works well when combined with gut repair and diet changes
Zinc, Quercetin, and Nettles
These are often called "natural antihistamines"—and while they can be part of a support plan, they aren't cure-alls.
Zinc is essential for skin healing and immune function—but must be given in balance
Quercetin can support histamine regulation but needs a healthy liver and gut to work effectively
What About Protein Changes? Does That Really Help?
Protein changes can be useful, especially if your dog has developed a sensitivity to a commonly fed source like chicken or beef. But again, if we just rotate through proteins without healing the gut, you’ll eventually run out of novel proteins.
What works better?
Use a cooling protein (according to TCVM) for dogs with red, inflamed skin
Pair with a simplified ingredient list for a short time—just long enough to reduce the inflammatory load
Add in gut repair supplements, food energetics, and calming herbs
Consider lightly cooked instead of raw during this phase if your dog is depleted or runs cold
The Real Question Isn’t “What Supplement?” — It’s “What System Needs Support?”
That’s the mindset shift I guide pet parents through. We’re not chasing symptoms—we’re asking:
Is the gut inflamed or damaged?
Is the liver congested or sluggish?
Is the immune system overreactive due to past exposures or imbalance?
Is there stored trauma affecting the nervous system and skin?
Are we feeding the yeast without realizing it?
From there, we build a protocol that may include:
Nutrition (fresh, cooling foods, gut-supportive herbs)
Digestive support (enzymes, probiotics, prebiotics)
Detoxification (binders, drainage remedies, essential oils)
Immune regulation (homeopathy, functional mushrooms, fulvic/humic minerals)
Emotional support (Reiki, Raindrop Technique, The Emotion Code)
This Is Why I Build Custom Plans for My Clients
Because your dog isn’t a statistic.
She’s not just a “yeasty dog” or an “allergy case”—she’s a living, breathing being with unique history, genetics, exposures, emotions, and needs.
Some dogs recover quickly with just food changes and minor gut support. Others need deeper healing work that includes lymphatic drainage, mineral rebalancing, or essential oil detox.
You don’t have to guess your way through it.
Top 5 Things to Do Today
Consider an elimination diet to identify food-based intolerances
Replace harsh shampoos and cleaning products with gentle, natural alternatives
Use Epsom salt soaks , herbal teas, or vinegar rinses to calm itchy paws
Focus on gut healing and detox—not just symptom control
