Seasonal Allergies in Dogs and Cats: Why the Itching Comes and Goes
Recognizing Environmental Triggers and Supporting Your Pet Through Flare-Ups

Pollen, grass, and mold are common seasonal triggers for itching in dogs and cats.
Does your dog or cat itch more in the spring, summer, or fall? You may notice more scratching, licking the paws, or problems with the skin and ears. These may be seasonal allergies caused by something your pet is coming in contact with outside. For some pets, the problems only last a few weeks. Others may have symptoms for several months.
When I work with pets with allergies, I do not look at the itching alone. I also look at the diet, digestive health, supplements, environment, and any other health problems that may be contributing to the problem.
Signs of Seasonal Allergies
Seasonal allergies can affect pets in different ways. Some pets itch occasionally, while others scratch and lick constantly. Some common signs include:
- Itchy skin
- Licking or chewing the paws
- Red or irritated skin
- Scratching the ears
- Recurring ear problems
- Rubbing the face
- Watery eyes
- Sneezing
- Hair loss from scratching or licking
- Hot spots
- Skin infections
Does your pet's itching seem to come and go with the seasons?

What Can Trigger Seasonal Allergies?
Many things your pet comes in contact with outside can trigger seasonal allergies. The time of year and where you live can also make a difference.
Some common triggers include:
- Grass pollen
- Tree pollen
- Weed pollen
- Ragweed
- Mold
- Mildew
- Dust
The Difference Between Seasonal and Food Allergies
Seasonal and food allergies can cause many of the same problems, which can make it difficult to know what is bothering your pet.
If your pet has seasonal allergies, you may notice the same problems coming back around the same time every year. Food allergies are more likely to cause problems throughout the year.
Some pets can have both seasonal and food allergies. This is why I look closely at what your pet is eating, when the symptoms started, and whether the problems come and go during different times of the year.
How Diet May Help
What you feed is important when dealing with allergies. A poor-quality diet can make it harder for the body to deal with allergy problems. I recommend foods made with high-quality animal protein and without a lot of fillers, artificial colors, preservatives, and flavors. To learn more about what to look for in a high-quality pet food, read my article, “How to Read a Pet Food Label.”
If I suspect the food is adding to the problem, I usually recommend changing the protein, trying a different food, or using a homemade diet. With a homemade diet, you control the ingredients.
Supplements for Seasonal Allergies
Certain supplements may be helpful for pets with seasonal allergies, but I do not recommend giving the same supplements to every pet.
Depending on the pet, I may recommend:
- Omega-3 fatty acids: Often reduce skin inflammation and soothe scratching.
- Probiotics: May help support a healthy immune response.
- Quercetin: May help with your pet's response to environmental allergens.
- Supplements for skin and coat support
- Other vitamins and minerals when needed
The supplements I recommend depend on your pet's diet, symptoms, medications, and overall health.
Reducing Seasonal Allergens Around Your Pet
You cannot completely avoid pollen, grass, and other outdoor allergens, but there are things you can do to reduce how much your pet brings into the house.
Some things that may help include:
- Wipe your pet's paws and legs after being outside
- Wash bedding regularly
- Vacuum frequently
- Keep your pet off freshly cut grass when possible
- Avoid walking through areas with tall weeds
- Bathe your pet as needed to remove pollen from the skin and coat
- Keep windows closed when pollen counts are high
When to See Your Veterinarian
Itching is not always caused by seasonal allergies. Fleas, food allergies, skin infections, parasites, or another health problem may be the cause.
If your pet is constantly scratching, has raw or irritated skin, or is having problems with the ears, have your veterinarian check your pet.
Once you know what you are dealing with, you can make better decisions about the diet, supplements, and changes that may help.
An Individualized Approach to Seasonal Allergies
Seasonal allergies are not the same for every pet. During a consultation, I look at what your pet is eating, when the itching started, what time of year it happens, what medications and supplements your pet is taking, and any other health problems. I use this information to develop a nutritional and holistic program based on your pet's individual needs.
If your dog or cat continues to struggle with seasonal allergies and you would like help with diet, supplements, and natural support, contact For Pet Health to schedule a consultation.
Frequently Asked Questions
What are the signs of seasonal allergies in dogs?
Itching, licking, or chewing that flares up during certain times of year, along with red skin, recurring ear infections, and sometimes watery eyes or sneezing.
Can cats get seasonal allergies too?
Yes. Cats can react to the same airborne triggers as dogs, including pollen, grasses, and mold, though symptoms can look a little different from pet to pet.
How do I know if my pet's itching is seasonal or food-related?
Seasonal allergies tend to flare and ease with the time of year, while food sensitivities usually cause symptoms year-round. Tracking the timing and ruling out fleas and food with your veterinarian can help narrow it down.
What triggers seasonal allergies in dogs and cats?
Common triggers include tree, grass, and weed pollen, mold spores, and indoor dust mites, with different triggers more active depending on the season.
How can I naturally help my dog or cat during allergy season?
Wiping down paws and fur after time outdoors, feeding a high-quality diet, reducing indoor allergen buildup, and considering individualized supplement support can all help. A personalized plan is often more effective than a one-size-fits-all approach.
