In this episode of Pet Health Unlocked, Alex Pearson and Dr. Keith Weingart discuss one of the most common and frustrating issues they hear about from pet owners: allergies. The conversation was sparked by Alex’s own dog, March, who came home from a walk and began sneezing uncontrollably for several minutes. What started as something almost funny quickly turned into a reminder of how sudden and unsettling allergy symptoms can be.
Allergies in pets rarely have a single, simple cause. Dr. Keith describes them as an overreaction of the immune system to things that should normally be tolerated, such as pollen, dust, molds, grasses, and other environmental elements. In dogs and cats, these reactions most often show up on the skin rather than as the sneezing and watery eyes people typically experience.

Why Allergies Develop
There is often a genetic component. Some dogs are born with a predisposition (called atopy) that makes their immune systems more reactive to everyday substances in the environment. Symptoms frequently become more noticeable around two years of age as the immune system matures.
At the same time, gut health plays a major role. When the intestinal barrier is compromised (sometimes called leaky gut), food particles and other substances can trigger broader immune responses. This can lead to itching, ear issues, paw licking, and anal gland problems even when the primary trigger is not a specific food. Many younger dogs with allergy-like symptoms are actually dealing with gut imbalances and food sensitivities first.
Over time, ongoing immune stress from any source can make the system more reactive, which is why some pets seem to develop new sensitivities later in life.
The Limits of Suppression
Conventional treatments have grown stronger at turning off symptoms, but they often do not address why the immune system became overreactive in the first place. While these medications can be necessary for comfort and quality of life, Dr. Keith notes that the goal in an integrative approach is to calm and rebalance the immune response rather than simply suppress it.
Where to Start
The foundation remains the same as with most health concerns. Fresh, whole, real food is the most important daily input. Highly processed diets can contribute to gut inflammation and make allergic tendencies worse. When a pet is showing clear allergic symptoms, one of the first steps is often to evaluate and improve the diet, sometimes by rotating to a novel protein in fresh form.
From there, supporting gut health becomes a priority. Even when a dog or cat is not showing obvious digestive issues, reducing gut inflammation and strengthening the intestinal barrier can lower the overall immune burden. The Gut Health Formula is frequently used as a foundational support in these cases because it helps calm inflammation, support tight junctions, and encourage a healthier microbial balance.
Targeted Support for the Immune Response
Once the gut is being addressed, additional tools can help modulate the overactive parts of the immune system. Ingredients such as quercetin and curcumin (found in the Longevity Complex) are helpful for calming histamine responses and supporting a more balanced inflammatory state. Omega-3 fatty acids from Super EPA Vet support skin integrity, which is especially relevant since allergies so often manifest in the skin.
Moducare Vet, a simple combination of plant sterols, is one of Dr. Keith’s preferred options for helping tone down an overreactive immune system while also supporting areas where it may be deficient. Colostrum has also become a useful addition for many allergic pets because it provides immunoglobulins and other compounds that support both gut health and mucosal immune balance on the skin and respiratory surfaces.
The emphasis throughout is on being specific rather than giving every supplement at once. A targeted approach tends to be more effective and easier for the body to respond to.
Advanced Options and Realistic Expectations
Testing has improved. Serum allergy testing and skin testing can help identify specific environmental triggers, which then allows for allergen-specific immunotherapy. This approach gradually retrains the immune system over months or years and is often one of the most effective long-term strategies available.
Dr. Keith is also clear that there does not have to be an all-or-nothing philosophy. When symptoms are severe, conventional medications may still be needed for comfort. Supplements can be used alongside them to help mitigate side effects and support the body more broadly. The priority is always the individual animal’s quality of life.
Moving Forward
Allergies remain one of the most challenging conditions to manage because they are so visible and persistent. Pet owners often feel the effects as much as their animals do, since constant itching and discomfort affect everyone in the household.
The encouraging part is that there are now more thoughtful ways to approach the problem than simply suppressing symptoms. Starting with diet and gut health, then layering in targeted immune and skin support, gives many pets meaningful relief while working toward longer-term balance.
We are currently developing a dedicated allergy support formula that will combine several of these principles into one product. We will share more as it becomes available.
In the meantime, our Gut Health Formula, Longevity Complex, Moducare Vet, and Super EPA Vet are among the products frequently discussed for allergic pets. You can explore them here on our website.
If your dog or cat is struggling with allergies, we encourage you to work with an integrative veterinarian who can help tailor a plan. We are also happy to help answer questions. Feel free to reach out through email or social media with your specific situations.
Pets are the best.
