10 Common Signs of Pet Allergies Every Pet Owner Should Know

By rachellambrose, 29th January 2025

As pet owners, we cherish the bond we share with our animals, but sometimes, both pets and their human companions can face challenges related to allergies. Just like humans, pets can suffer from allergies to a variety of environmental factors, food, or even certain substances they come into contact with. Identifying the signs of pet allergies early on can help prevent discomfort for your pet and avoid potential health issues. In this blog, we will explore the most common signs of pet allergies and how to manage them effectively.

Pet allergies symptoms management

1. Itchy Skin and Excessive Scratching

One of the most obvious signs of pet allergies is itching. Pets suffering from allergies often scratch excessively, lick, or bite their skin. This is typically a result of environmental allergens such as pollen, dust mites, or mold, but it can also be triggered by flea bites or food allergies. If you notice your pet scratching more than usual or focusing on specific areas of their body (like their paws, ears, or belly), it’s time to investigate further.

2. Ear Infections and Inflammation

Another common sign of pet allergies is recurrent ear infections. Allergies, particularly to food or environmental factors, can cause inflammation in the ears, making them red, swollen, or inflamed. Your pet may frequently shake their head or scratch their ears in response to the irritation. You may also notice a foul smell or discharge coming from their ears. Chronic ear infections can lead to more serious issues if not addressed, so it's essential to consult a veterinarian.

3. Runny Nose and Sneezing

Much like humans, pets can develop respiratory symptoms in response to allergens. If your pet is constantly sneezing, has a runny nose, or exhibits nasal discharge, it could be a sign of pet allergies. Pollen, dust, or other environmental allergens can trigger these symptoms in both cats and dogs. These symptoms may worsen during specific seasons, such as spring or fall, when pollen counts are higher.

4. Watery Eyes

Allergic reactions can lead to watery eyes in pets, making them appear teary-eyed or red-eyed. If your pet's eyes are constantly watering or you notice signs of conjunctivitis (swelling and redness around the eyes), it could be due to environmental allergens or irritants. This condition can also be exacerbated by certain foods or substances your pet comes into contact with.

5. Digestive Issues and Vomiting

While digestive issues aren’t always the first sign of allergies, they can still be a prominent symptom. Pets with food allergies may experience vomiting, diarrhea, or gas after eating specific ingredients. Common allergens in pet food include grains, chicken, beef, and dairy products. If your pet’s gastrointestinal system is frequently upset after meals, it could indicate a food allergy. You may need to consult your vet to identify the specific trigger.

6. Hives or Skin Rashes

Hives or skin rashes are visible signs of an allergic reaction in pets. These raised, red bumps may appear on your pet’s skin, often around the neck, face, or belly. Hives can be caused by an allergic reaction to certain foods, insect bites, or environmental allergens like pollen or mold. If your pet develops hives, it is important to monitor them for other allergic reactions and contact a veterinarian for guidance on treatment.

7. Behavioral Changes

Pets that are suffering from allergies may show signs of distress, irritability, or fatigue. Itchy skin, digestive discomfort, or constant sneezing can make them feel miserable, leading to changes in their behavior. Your pet may become more withdrawn, less active, or even exhibit signs of aggression if they’re in pain or discomfort due to allergies. If your pet suddenly changes their behavior without an apparent reason, allergies could be the cause.

8. Hair Loss and Bald Patches

Excessive scratching, licking, or biting can lead to hair loss in pets. If your pet is constantly trying to relieve itchiness caused by allergies, it can result in bald patches, thinning fur, or even skin infections due to the constant irritation. Hair loss, especially if it’s concentrated around a specific area, may indicate an allergic reaction. If you notice changes in your pet's coat, consult your veterinarian for an allergy test to determine the underlying cause.

9. Swelling or Puffiness

Allergic reactions can also cause swelling in pets. This is especially common in cases of insect stings, bites, or exposure to certain allergens. The swelling may appear around the face, paws, or other parts of the body. If you notice your pet’s face becoming puffy or their paws swelling, it’s crucial to seek immediate veterinary attention to prevent further complications, especially if your pet is having trouble breathing.

10. Licking of the Paws

Licking the paws is another common sign of pet allergies. If your pet is frequently licking their paws, it could be an attempt to relieve discomfort caused by environmental allergens such as pollen or dust. It may also be a sign of a food allergy or an irritation caused by chemicals, shampoos, or cleaning products. Chronic paw licking can lead to secondary infections, so it’s important to address the issue early.

How to Manage and Treat Pet Allergies

If you notice any of these signs of pet allergies in your pet, it’s important to act quickly to alleviate their discomfort. Here are some steps to manage your pet’s allergies:

  • Visit the Veterinarian: The first step in addressing allergies is a visit to your veterinarian. They will help determine the specific allergen causing the reaction through tests or elimination diets and recommend the best course of treatment.
  • Allergy Medications: Depending on the severity of your pet's symptoms, your vet may prescribe antihistamines, corticosteroids, or other allergy medications to help control itching, inflammation, and discomfort.
  • Avoid Allergens: If possible, try to reduce your pet's exposure to the identified allergens. This may include using air purifiers, cleaning your pet’s bedding regularly, or switching to a hypoallergenic pet food if food allergies are suspected.
  • Specialized Diets: For food allergies, your veterinarian may recommend a special diet that avoids common allergens and introduces new proteins to minimize allergic reactions.
  • Flea and Tick Prevention: Flea infestations can cause allergic reactions in pets, so maintaining a regular flea prevention regimen is essential to avoid this common allergen.
  • Regular Grooming: Regularly grooming your pet can help reduce exposure to environmental allergens like pollen, dust, and mold. Bathing your pet with hypoallergenic shampoos can also provide relief from itching and irritation.
