Fall Allergies: Their Causes, Symptoms and Solutions
As the crisp fall air brings relief from the sweltering heat of summer, many of us look forward to the beauty that the change of seasons brings- cooler temperatures, colorful leaves, and fun festivals. However, for our pets, fall can mean the onset of seasonal allergies. Just as humans are susceptible to allergic reactions to environmental changes, our pets can suffer the same unpleasant effects. Understanding these allergies is crucial to finding the right treatment that can relieve your pet’s symptoms. Let’s look at the top causes of allergies in the fall and what you can do about them.
Cause of Fall Allergies in Pets
Basically allergies are the result of the immune system overreacting to an otherwise harmless foreign substance, otherwise known as an allergen. Fall allergies in pets are primarily caused by environmental factors that come with the change in weather. While allergies can be from contact or ingestion, it is inhalant allergies that are most problematic with the change of season. Common triggers include:
Pollen: Many people think of pollen as a “spring allergy” but fall pollen can create havoc for allergy suffers, pets included. Ragweed, sagebrush, and other plants and weeds disperse their pollen causing allergic reactions in pets, especially those with pre-existing sensitivities. While ragweed can peak in September in Middle TN and usually ends by mid November, above normal temperatures can make it stretch well into December.
Mold: Mold is certainly not exclusive to fall but the moist dewy mornings and rainfall on damp fallen leaves creates a haven for growing mold spores. Decomposing plant material left on the ground to rot allows for bacteria and fungus to thrive.
Fleas: Fall can be one of the worst seasons for flea infestations. Flea allergy dermatitis is the most common dermatological issue for dogs and can make an animal miserable with intense itching. This necessitates year-round application of preventatives.
Dust Mites: Again, this isn’t exclusive to fall but when we turn on the heat in our homes it can become a bigger problem. These microscopic pests thrive in warm, dusty environments, exacerbating allergy symptoms in pets who are indoor more during the cooler weather.
Food : With the onset of fall, you might be tempted to give your pet seasonal treats. Popular ingredients like pumpkin, while healthy for some pets, can cause digestive issues or allergic reactions in others.
Symptoms of Fall Allergies in Pets
Pets suffering from allergies can exhibit a wide range of symptoms, which can vary in severity. Common signs include:
Itchy Skin – Itchy skin will cause pets to scratch, bite, or chew at their skin more frequently. If excessive, secondary infections and hair loss can occur when the cause is not addressed promptly.
Red or Inflamed Skin -Allergies can cause dermatitis, leading to red, inflamed, or flaky skin. Hot spots or rashes might develop, which can cause even more scratching and irritation.
Ear Infections– Allergies can cause ear infections. Look out for itching, scratching, redness, discharge, head shaking, rubbing of the head, or a foul odor. Dual ear infections are usually caused by allergies.
Eyes and Nose Discharge – Just like humans, common signs of allergies in pets include runny eyes and a runny nose. Yellow or green discharge may indicate infection.
Sneezing and Coughing – More classic signs of allergies. Respiratory symptoms, including sneezing and coughing, are caused by inhaled airborne allergens.
Chewing on Paws – Some dogs lick and chewy their paws habitually but if this is a new behavior for yours, then allergies are likely the culprit.
Digestive Issues- Allergies sometimes lead to vomiting or diarrhea, especially if the allergen is ingested.
Managing & Treating Fall Allergies
Relieving your pet’s suffering from allergies relies on a combination of preventive measures and treatments:
Flea Prevention – Keeping up-to-date with flea preventative can significantly reduce the risk of flea allergy dermatitis. These are just as important during fall and winter as they are during the warmer seasons.
Regular Grooming – Frequent brushing and bathing can help remove allergens from your pet’s coat and skin. Consider using hypoallergenic shampoos and grooming products to soothe irritated skin.
Cleaning Indoors and Out- Regularly cleaning your home helps reduce dust mites and mold. Frequently vacuum carpets with a HEPA filter and wash your pet’s bedding regularly. Consider air filters as this will improve the air quality indoors for both you and your pet. Outside, make yard clean up a priority and don’t let sodden rotting leaves accumulate.
Limit Outdoor Exposure- With high pollen or mold counts, it may be necessary to spend more time indoors playing with treat balls or toys. After walks or outdoor play, wipe your pet’s paws and coat to remove allergens. Time walks and outdoor activities with more care. Pollen is lower in the mornings; several days of rain means a high mold count in the air.
Consult Your Veterinarian – If your pet shows signs of allergies, consult a vet. There are various prescriptions to lessen allergy symptoms including antihistamines, corticosteroids, or other medications. Antibiotics will be needed if secondary infections have developed and ointments or drops may be needed for skin irritations and ear infections. Never treat your pet with any human medication; let your vet determine what medication is the best treatment for them. In cases of severe allergies, your vet may suggest testing to identify specific allergies and pinpoint more effective treatment.
Dietary Adjustments If you suspect food allergies, try an elimination diet under veterinary guidance to determine which ingredients may be causing a reaction.
Fall allergies in pets can make the season an unpleasant one for those who suffer from them. But it’s important to make sure that the symptoms you’re seeing in your pet are allergies and not something else. Respiratory issues, for example, can be a sign of something far more serious than allergies. This is why its always best to check with your vet and get a definitive diagnosis. With their help you can get on a course of proactive management and treatment that should lessen, if not eliminate, your pet’s symptoms. Then you can ensure that your pet enjoys the season as much as you do, without the discomfort of allergies.
