Many dog owners are familiar with the idea that their pets can have allergies, but did you know that dogs can be allergic to grass? Grass allergies occurs often in dogs and can lead to a range of symptoms that impact their comfort and health.
In this blog post, we’ll explore how dogs can be allergic to grass, learn to recognize the signs, and what you can do to manage this type of allergy.
What Are Grass Allergies in Dogs?
Grass allergies are common in dogs and occur as inhalant or contact allergies triggered by grass pollen. Since grass pollen is airborne, your dog doesn’t need to be on the grass to experience symptoms. These allergies can cause skin reactions or upper respiratory issues.
Grass allergies tend to be worse in the spring and fall when pollen levels are high, but they can affect dogs year-round. In dogs, grass pollen allergens are absorbed through the skin and mucous membranes. Dogs with grass allergies often also have other sensitivities, like flea or food allergies.
While grass allergies can develop at any age, most dogs begin showing symptoms after their first year due to repeated exposure. Although these symptoms can be uncomfortable, the good news is that they are typically not life-threatening.
What Are the Signs of Grass Allergies in Dogs?
The signs of grass allergies in dogs can vary, but common symptoms include:
Excessive scratching, licking, or biting, especially around the paws, belly, and groin area.
Visible redness, inflammation, or rashes on the skin.
Frequent ear scratching, head shaking, or a buildup of wax and debris. These are symptoms of an ear infection.
Excessive tearing or redness in the eyes.
Frequent sneezing, runny nose, or clear nasal discharge.
Bald patches or thinning fur due to persistent scratching or licking.
Inflamed, moist, and painful skin lesions caused by constant irritation.
A severe allergic reaction called anaphylaxis is rare in dogs. When it does occur, it typically happens within 5–30 minutes of exposure to the allergen. Signs of anaphylaxis in dogs may include:
- Severe hives
- Facial swelling, particularly around the eyes and muzzle
- Wheezing or difficulty breathing
- Rapid breathing
- Vomiting and diarrhea, which may contain blood
If you notice these symptoms in your dog, please take your dog to the nearest veterinary clinic as soon as possible.
Which Types of Grass Can Trigger Allergies in Dogs?
Dogs can be allergic to a variety of grasses, similar to how people can be sensitive to different types of pollen. Here are some common grasses that might trigger allergies in dogs:
Bermudagrass
Bermudagrass is a warm-season grass commonly used in lawns and sports fields. It produces pollen that can cause allergic reactions in sensitive dogs.
Ryegrass
Ryegrass, often used for lawns and pastures, can also be a common allergen for dogs. It is known for producing allergenic pollen.
Fescue
Various types of fescue grasses are used in lawns and forage. Some dogs can be allergic to the pollen produced by these grasses.
Bahia Grass
Common in warm climates, Bahia grass is another type that may contribute to allergic reactions in dogs.
How Are Grass Allergies Diagnosed in Dogs?
Veterinarians typically use a comprehensive approach to diagnose grass allergies in dogs. First, they will begin by discussing any symptoms you’ve noticed, such as itching, redness, or respiratory and digestive issues.
Next, the doctor will perform a physical exam on your dog. A thorough examination of the skin and haircoat to check for hair loss, skin lesions, scratches, bump and red areas.
Finally, your vet will either recommend some topical products for the haircoat and skin, or tell you that diagnostic testing is needed. As a veterinarian, I usually suggest skin tests, blood tests, or elimination diets. Skin tests involve exposing a small area to various allergens, including grass, to observe the dog’s reaction. In my experience, blood tests can help identify specific allergens by analyzing the dog’s immune response.
A holistic approach is always best, taking into account the pet’s medical history, lifestyle, and environmental factors. This thorough process helps to create a personalized care plan, so your dog can enjoy the grassy outdoors.
What Is Involved in Allergy Testing for Dogs?
Your veterinarian may perform serum blood tests to check for allergies, but the most accurate method is the Intradermal Skin Test. This test is considered the gold standard and is typically done under mild sedation.
It involves shaving one side of the dog’s abdomen and injecting specific allergens into the skin.
The injected area is then observed for any signs of hives, which indicate an allergic reaction to a particular allergen. Once the allergens are identified, a tailored treatment plan is created for your pet.
Another option for managing allergies is hyposensitization therapy, which involves “micro-dosing” your pet with the allergen to gradually build resistance over time.
How Are Grass Allergies Treated in Dogs?
The goal of treatment for grass allergies in dogs is to manage symptoms, as a complete cure is often not possible. Treatment will depend on how severe the symptoms are, so it’s always best to consult your veterinarian for best options.
Natural Remedies for Grass Allergies in Dogs
If symptoms are mild, the following topical therapies may be helpful:
Antihistamines
Benadryl® may help with watery eyes, runny noses, and sneezing, but it is generally not effective for skin allergies (allergic dermatitis). Always check with your vet for the correct dosage before giving any medication, even over-the-counter ones.
Bathing with a Hypoallergenic or Oatmeal-Based Shampoo
Regular bathing with a mild, hypoallergenic, or oatmeal-based pet shampoo can help remove allergens from the skin before they are absorbed, potentially reducing itching. These shampoos are readily available without a prescription.
Using a Medicated Shampoo
While medicated shampoos may not be enough to treat an active infection, they can help prevent infections by removing allergens and reducing bacteria and yeast on the skin. Your vet can recommend the best medicated shampoo for your dog.
Fatty Acids
Omega supplements and fatty acids can help reduce skin inflammation and general itchiness in dogs.
Quercetin
This natural supplement has antihistamine and anti-inflammatory properties that may reduce allergic reactions by suppressing the release of histamine.
Probiotics
Balancing gut health can indirectly impact immune responses, potentially alleviating allergies.
What Prescription Treatments Are Available for Grass Allergies In Dogs?
Steroids – Medications like prednisone, or Temaril-P, which contain steroids, may be prescribed for severe itching. These are available only by prescription and are usually recommended for short-term use due to potential side effects from long-term administration.
Allergy Medications – Your vet might prescribe Apoquel® (a daily oral tablet) or Cytopoint® (an injection given every four to eight weeks) to help relieve itching. Both are prescription medications, and your veterinarian will decide which option is best for your dog.
Immunotherapy or Hyposensitization Therapy – If allergy testing (either blood or intradermal) has identified specific allergens, immunotherapy can be used. This treatment involves either weekly injections or an oral liquid medication, customized for your dog based on the allergy test results.
How Can You Prevent Grass Allergies in Dogs?
Preventing grass allergies in dogs can be challenging, but there are several steps you can take to minimize exposure and reduce symptoms:
- Reduce your dog’s time in grassy areas, especially during peak allergy seasons like spring and fall when pollen levels are high.
- Bathe your dog regularly with a hypoallergenic or oatmeal-based shampoo to remove allergens from their skin and coat before they cause irritation.
- Clean your dog’s paws, belly, and coat with pet wipes or a damp cloth after outdoor walks to remove grass pollen and other allergens.
- Frequently vacuum carpets and wash your dog’s bedding to remove pollen and allergens that may be brought inside.
- Consider using air purifiers in your home to help reduce airborne allergens like grass pollen.
- Keep your grass trimmed short to reduce pollen production and prevent your dog from coming into direct contact with tall grasses.
Wrapping It Up – Grass Allergies In Dogs
Grass allergies in dogs can be a frustrating challenge for both pets and their owners, but with the right knowledge and care, they can be effectively managed. By understanding the signs, working closely with your veterinarian for a proper diagnosis, and taking preventative measures, you can help your dog enjoy a happier, itch-free life—even during allergy season.
Remember, every dog is unique, so finding the right combination of treatments and lifestyle adjustments is key to keeping your furry friend comfortable and healthy.
