Seasonal Allergy Supplements for Dogs: A Pet Owner’s Guide

Quick takeaway: Seasonal allergy supplements are formulated to help support dogs during periods of heightened environmental allergens, typically in spring and fall, when pollen counts spike. When choosing a seasonal allergy supplement, it’s important to consider ingredient transparency, formulation quality, and palatability. Be consistent in giving your dog their seasonal allergy supplement every day at the same time, according to instructions. It can take up to 3 months for your dog to receive the full benefits.

Seasonal Allergies In Dogs

Is your dog showing signs of discomfort as the seasons change? Some pups are prone to seasonal allergies that show up when they are exposed to environmental triggers like pollen or grass. If you’re noticing your dog seems to have fluctuating energy, appears to be scratching or shaking their head more, or just seems a little bit “off,” then it might be time to explore the possibility of adding a seasonal allergy supplement to their daily routine.

In this article, we explore the potential benefits of seasonal allergy supplements for dogs, how to choose the right product for your pup, and what to consider before making any changes. Remember, it’s important to consult your dog’s vet before introducing a new supplement, and always follow the product’s directions for use.

What Are Seasonal Allergy Supplements for Dogs?

Seasonal allergy supplements are health supplements formulated to help support dogs during periods of heightened environmental allergens, typically in spring and fall when pollen counts spike. They may be helpful for dogs showing signs such as paw licking, head shaking, or scratching that may be linked to seasonal changes.

In general, these supplements aim to support immune function, gut health, and the skin’s natural barrier. Ingredients often include probiotics, omega fatty acids, and antioxidants, which are known to help maintain normal inflammatory responses and promote skin and coat comfort.

PetLabCo.’s Allergy & Immune Chews, for example, are formulated with a blend of probiotics, postbiotics, and beneficial nutrients such as Colostrum, Omega-3 from Krill Oil, and prebiotics like FOS and GOS. These pork-flavored soft chews are designed to support a normal immune response, promote gut health, and may help with occasional skin discomfort associated with seasonal changes. Pet owners give the tasty, pork-flavor soft chew to their dogs once a day, and many pet parents find them easy to give as part of their dog’s daily routine. 

Key PetLabCo. Allergy & Immune Chew Benefits:

  • Supports immune function
  • Promotes seasonal comfort
  • Maintains gut health
  • Can help with intermittent itchiness
  • Supports skin and coat health
  • Formulated with probiotics, prebiotics, and postbiotics

How Do I Choose A Seasonal Allergy Supplement For My Dog?

When choosing a seasonal allergy supplement, it’s important to consider:

  • Ingredient transparency: Look for products that list active ingredients like probiotics (e.g., Bacillus coagulans), prebiotics (e.g., FOS, GOS), and beneficial oils (e.g., Borage or Krill Oil).
  • Formulation quality: Make sure the supplement is tailored for dogs and not repurposed from human products. Products reviewed by veterinarians or formulated by nutritionists are more likely to have high quality ingredients that provide multiple benefits for your pup.
  • Product format and palatability: Soft chews may be more enjoyable for dogs than powders or capsules, especially if they’re flavored.

What Other Strategies Can I Use To Manage My Dog’s Seasonal Allergies?

In addition to a supplement, here are some strategies to help manage your dog’s seasonal sensitivities:

  • Regular grooming and paw cleaning to remove pollen and irritants.
  • HEPA air filters to reduce airborne allergens indoors.
  • Limiting outdoor exposure during high pollen times (early morning and windy days).
  • Using a vet-recommended shampoo designed to support skin comfort.

While supplements can support your dog’s immune system and skin health, combining them with environmental controls gives a more well-rounded approach to seasonal support.

When Should I See a Vet About My Dog’s Seasonal Allergies?

While mild, occasional discomfort may be supported by health supplements, you should consult your veterinarian if:

  • Signs of discomfort persist beyond seasonal changes.
  • Your dog shows signs of worsening discomfort.
  • Your dog seems lethargic or uninterested in food.

Your vet will be able to advise on the best course of action – it is very important to stick to your annual, or semi-annual visits, and to seek support straight away if you are concerned about your dog’s wellbeing.

Conclusion: Seasonal Allergy Supplements for Dogs

Adding a seasonal allergy supplement like PetLabCo.’s Allergy & Immune Chews to your dog’s routine during high-pollen months may help support their gut health, immune system, and overall comfort. Choose a supplement that’s easy to give as part of your dog’s daily routine, and which your dog finds palatable. Opt for a product with transparent ingredient information, ideally one that is nutritionist-formulated and vet-reviewed, for added peace of mind.

As always, chat with your vet before introducing anything new to your dog’s routine, and follow the instructions on the tub to keep your best friend feeling their best.
