Understanding Your Dog’s Silent Cues: The First Step to Relief

If you are reading this, you likely know that something “just isn't right” with your pup. Whether it's constant scratching, digestive issues, or just a lack of energy, our dogs have a way of telling us when they are in distress, even if they can't speak.

Below, we cover the top symptoms of intolerance. But first, if you are tired of guessing what's wrong, there is a faster way to know.

⚡ The Quick Answer (For Busy Pet Parents)

If you recognize the symptoms in this article, it is often due to a specific food or environmental trigger (like chicken, wheat, or grass pollen).

Don't guess with expensive food trials. We recommend using an at-home intolerance test to pinpoint the exact trigger immediately.

Our #1 Recommended Test: UCARI Pet Intolerance Test (Results in 48 Hours)

The Top 8 Symptoms to Watch For

1. Ear Infections

Frequent ear infections can be a sign of underlying sensitivities, especially if they recur despite treatment. Dogs may shake their heads or scratch their ears excessively due to the discomfort.

2. Digestive Troubles

Sensitivities or intolerances to certain food ingredients can manifest as various digestive issues. Symptoms include vomiting, diarrhea, excessive gas, and even changes in appetite. These signs can indicate that your dog’s body is reacting negatively to something in their diet.

3. Itchy Skin (Pruritus)

Dogs with food or environmental sensitivities often experience relentless itching. This discomfort can lead to excessive scratching, biting, or licking, particularly around the ears, paws, belly, and rear. Itchy skin can escalate to more severe conditions, such as infections or hot spots, if not addressed promptly.

🛑 Stop the Itch, Don't Just Mask It.

Did you know that 90% of scratching is caused by a specific trigger? Shampoos and creams only hide the problem temporarily. To stop the itching for good, you need to identify exactly what your dog is reacting to.

4. Hot Spots

Also known as acute moist dermatitis, hot spots are areas of swollen, infected skin that appear suddenly and grow rapidly. These painful spots result from your dog’s over-grooming areas that itch due to allergies.

5. Respiratory Symptoms

While less common, sensitivities can lead to respiratory symptoms in dogs, such as sneezing, coughing, and wheezing. These symptoms are more often associated with environmental allergens like pollen, dust, or mold.

6. Paw Licking and Chewing

Excessive licking or chewing of the paws is a common sign of discomfort in dogs with sensitivities. This behavior can lead to irritation, infection, and further skin damage.

💡 Is it the Food or the Environment?

Stomach issues are often caused by food, but did you know laundry detergent or pollen can also be the culprit? The UCARI Test scans for both food and environmental factors in one simple test.

 

7. Gastrointestinal Upset

Chronic gastrointestinal issues, such as frequent bowel movements, straining to defecate, or gurgly gut noises, can indicate food sensitivities or intolerances.

8. Dull Coat and Skin Flaking

A dull coat and flaky skin can be signs of nutritional deficiencies or reactions to certain foods. A healthy coat is often a reflection of overall health and proper nutrition.

The Hardest Part is Knowing What is Causing It

You’ve recognized the symptoms above, but now comes the difficult question: Is it the Chicken? The Wheat? Or maybe the pollen in the grass?

Traditionally, vets recommend an “Elimination Diet.” This involves weeks of changing foods, strictly monitoring every treat, and waiting to see if symptoms improve. It is expensive, time-consuming, and frustrating for a hungry dog.

There is a faster, easier way.

Modern at-home testing technology allows you to use a small hair sample to identify up to 1,000+ potential triggers. No needles, no vet visits, and no guessing.
