Peak Allergy Season: What Your Dog Needs
Vet Reviewed by Dr. Jacob Klos, DVM
May marks the collision of multiple allergen sources, making it one of the most challenging months for dogs with environmental sensitivities.
Why May is different
In early spring, tree pollen is the primary trigger. By May, grass pollen joins the mix. Simultaneously, mold spore counts are climbing as warmer temperatures and spring rainfall create ideal growing conditions. For allergic dogs, this layering effect means the immune system is responding to multiple triggers at once.
According to the American Kennel Club, environmental allergies (atopic dermatitis) are among the most common reasons dogs visit the veterinarian. The condition affects an estimated 10 to 15% of dogs, though many more show subclinical signs that owners attribute to normal behavior.
The signs are escalating right now
If your dog showed mild signs in March or April, May is often when those signs intensify:
- Constant paw licking, especially between the toes
- Face rubbing on carpet, furniture, or grass
- Red, inflamed ears with a yeasty smell
- Hot spots appearing seemingly overnight
- Belly rash or redness in the groin area
- Thinning coat or excessive shedding
- Restlessness and difficulty settling
These aren't seasonal quirks. They're signs of an immune system in overdrive.
What's happening under the skin
When allergens contact your dog's skin, the immune system releases histamine and other inflammatory compounds. This triggers itching, redness, and swelling. The dog scratches, which damages the skin barrier further, allowing more allergens to penetrate. More allergens trigger more histamine. The cycle escalates.
Breaking this cycle requires addressing both the external exposure and the internal response.
The action plan for peak season
- Reduce exposure: Wipe paws, belly, and face after every outdoor session. Wash bedding weekly in hot water. Run air filters indoors if possible.
- Support the skin barrier: Omega-3 fatty acids (EPA and DHA from fish sources) support skin barrier integrity and a healthy inflammatory response. Studies in veterinary dermatology have shown measurable improvements in dogs with atopic dermatitis when omega-3 supplementation is consistent.
- Manage the histamine response: Quercetin is a naturally occurring flavonoid with antioxidant properties that has been studied for its ability to support the body's management of histamine. It works best as part of a daily routine, not as a one-time intervention.
- Support gut health: The gut-skin axis means gut imbalances can worsen skin symptoms. Daily probiotics support microbial balance in the gut, which influences systemic inflammation and skin health.
- Be consistent: These interventions work cumulatively. Starting them after your dog is already miserable means you're playing catch-up. Daily, proactive support delivers the best results.
- Consult your vet: For dogs with severe allergies, prescription options may be appropriate. Early veterinary intervention can prevent secondary infections and reduce suffering.
Daily support that works with the season
Our Allergy & Itch Chews were formulated specifically for moments like this. Each daily chew delivers omega-3s from salmon oil to reinforce the skin barrier, quercetin to support the body's histamine response, and probiotics to maintain the gut-skin connection that drives so much of the allergic response. One chew per day, started now and maintained through the season, gives these ingredients the consistency they need to deliver real results.
