Seasonal Puppy Allergies: Signs, Support & When To Call The Vet 

Are you concerned that your puppy may have seasonal allergies? In this article, vet Liza Cahn DVM advises puppy parents on what seasonal puppy allergies look like, how the immune system and skin barrier work together, how to support your puppy at home, and when it’s time to call the vet. 

What Might Seasonal Puppy Allergies Look Like? 

As the seasons change, so do the allergens floating through the air, like pollen, dust, and mold spores. Seasonal sensitivities most commonly begin in dogs between six months and two years of age, and can result in paw licking, itching, scratching, sneezing, and watery eyes. Seeking veterinary guidance is always recommended when your dog shows signs of seasonal allergies; however, supplements and environmental modifications may also be helpful in managing mild skin sensitivities. 

Seasonal Allergy Support for Puppies: What Early Care Can Do

If your puppy is affected by seasonal changes, such as mild itching due to increased pollen levels or mild skin discomfort associated with the cooler months, they may benefit from a holistic care routine. This can include regular grooming, a complete and balanced diet, and vet-reviewed supplements such as PetLabCo.’s Allergy & Immune Chews, which are suitable for puppies aged 12 weeks and older. Supplements may play a supportive role in a broader wellness routine, but veterinary care is often essential for managing allergy-related discomfort.

How the Immune System and Skin Barrier Work Together

A dog’s immune system is the network of specialized cells and pathways throughout the body that identify and defend against foreign invaders like bacteria and viruses. The skin barrier is the outermost layer of the skin, composed of cells, lipids, and a community of beneficial microorganisms, which all function as a physical shield to block external substances from entering the skin. The immune system and skin barrier both have important roles in keeping your dog healthy, and in the case of seasonal or occasional allergies, they must both work together. 

A dog’s skin barrier is the first line of defense against the environment and physically blocks allergens, bacteria, and irritants from getting inside the body. It’s made of skin cells sealed together by a mixture of fats (lipids), including molecules called ceramides. The skin is also home to the skin microbiome, a balanced community of beneficial microorganisms. These good microbes help maintain a healthy environment on the skin’s surface. Within the skin, specialized immune system cells constantly monitor for any substances that have managed to get past the barrier. 

Dogs may be susceptible to seasonal or occasional allergies when this protective partnership fails. They may have a less-effective skin barrier, allowing environmental allergens to easily pass through the skin’s outer defenses. Once allergens make contact with the skin, a sensitive immune system may respond inappropriately, leading to itching that can result in further discomfort from repeated scratching.

PetLabCo.’s Allergy & Immune Chew – A Supportive Daily Supplement

Allergy & Immune Chews are a vet-reviewed supplement for dogs aged 12 weeks and older which may help support immune health and seasonal comfort. The soft chews are packed with high-quality ingredients, including:

• Quercetin – A natural plant-based compound with antioxidant properties, quercetin may help support a normal histamine response, which is a key part of maintaining seasonal skin comfort.
• Probiotics – These are the “good bacteria” that support a healthy gut microbiome, which in turn helps promote a balanced and appropriate immune response.
• Postbiotics – These are beneficial compounds produced by probiotics. They provide direct support to the gut and immune system.
• Krill and borage oil – This powerful blend of omega-3, 6, and 9 fatty acids helps support normal immune and inflammatory responses. They also strengthen the skin barrier to promote healthy and hydrated skin.

Can Supplements Help Support Seasonal Puppy Allergies?

Some pet owners choose to include vet-reviewed supplements in their puppy’s wellness routine. While these products aren’t a treatment for allergies, they can be part of a broader approach that includes nutrition, grooming, environmental management, regular check-ups, and veterinary treatments if needed. These supplements

• May help maintain immune balance
• May support healthy skin function
• Include probiotics to support gut health and immune response
• Promote seasonal comfort without being a medical product

At-Home Care For Seasonal Skin Discomfort in Puppies

In addition to supplements, the following vet-approved tips may help manage mild discomfort associated with seasonal changes: 

• Wipe off paws after coming inside – After every walk or time spent outside, wipe your dog’s paws, belly, and face with a damp cloth or unscented hypoallergenic wipe. This physically removes pollen and other allergens from their coat and skin before they can cause a reaction or be tracked into the house.
• Clean air – Keep windows closed during high-pollen seasons and use an air purifier with a HEPA filter in the room where your dog sleeps to minimize airborne allergens. 
• Clean floors and bedding – Vacuum carpets/rugs and wash your dog’s bedding (as well as your own if they sleep with you) frequently to remove allergens like dander, and pollen.

• Staying up-to-date with preventative care – visiting your vet regularly will ensure your dog always receives the requisite preventative care to help protect them from allergens that can cause reactions in sensitive dogs. 
• Consistent grooming – Regular grooming is a key part of managing allergies and maintaining a healthy skin barrier. Brushing removes loose hair, dander, and surface allergens, and prevents matting. Bathing with a canine-specific hypoallergenic shampoo helps wash away allergens and soothe the skin. Most dogs with healthy skin should not be bathed more than once a month, as it can result in dryness.

When Should I Take My Puppy to the Vet for Seasonal Allergies 

While occasional scratching is completely normal for most dogs, consistent signs of excessive allergic response require veterinary evaluation. Signs can include persistent head shaking, paw licking or chewing, scratching, sneezing, or changes to stool consistency. 

Schedule a veterinary appointment as soon as possible if you are concerned about your puppy’s wellbeing – they may be dealing with a year-round environmental allergy or an underlying health concern which requires support from a veterinarian.
