Treating My Dog Allergies from Grass

What are Grass Allergies in Dogs?

Grass allergies in dogs, also known as canine atopic dermatitis or atopy, are a type of allergic reaction to grass pollen or other grass-related substances. Dogs with this condition may experience itching, scratching, redness, and inflammation of the skin. The symptoms can be seasonal, depending on the prevalent grasses in the environment.

Grass allergies in dogs are more severe in spring and autumn as the difference in seasons results in more plant pollen in these two seasons, but they can develop in every season for allergy-stricken dogs. The dog's skin and mucous membranes are able to absorb the allergen (pollen) and produce symptoms, and many dogs with grass allergies have both flea and food allergic reactions.

Grass allergies can occur at every age, but most dogs begin to develop allergic reactions about a year after initial exposure to the allergen. Although allergy symptoms may be uncomfortable for the dog, most are not life-threatening.

Severe allergic reactions are relatively rare and usually occur within 5-30 minutes of exposure to the allergen.

Symptoms in dogs may differ from those in humans due to the different organs involved in shock. In dogs, you may see severe hives, facial swelling (especially around the eyes and muzzle), panting, difficulty breathing, and a rapid respiratory rate. There may also be vomiting and diarrhea, with or without blood.  

If you think your dog is experiencing an allergic reaction or see any of these symptoms, seek veterinary care immediately.

Dog Grass Allergy Symptoms

Itching

Due to intense itching, dogs with grass allergies may scratch or bite at their skin, paws, and ears.

Redness and inflammation

The skin may become red, inflamed, and irritated, particularly in areas where there is little hair, such as the groin, belly, and armpits.

Hair loss

Prolonged scratching and biting can lead to hair loss in affected areas.

Skin infections

Bacteria and yeast can infect the broken skin, leading to a secondary infection.

Sneezing and runny nose

In some dogs, grass allergies can cause sneezing, a runny nose, and watery eyes.

Ear infections

Grass allergies can cause ear infections due to inflammation and itchiness.

Licking and chewing

Dogs may lick or chew at their paws or other areas where they are experiencing discomfort.

Gastrointestinal problems: Some dogs with grass allergies may experience vomiting or diarrhea.

Causes of Grass Allergies in Dogs

The exact cause of grass allergies in dogs is not entirely understood, but it is believed to be caused by a reaction to the pollen or other proteins found in grasses, such as dogbane, cowslip, clover, or rye and the symptoms are similar to those caused by allergic reactions to pollen and seeds (ragweed, quinoa) from woody plants (fir, pine, and oak). When a dog with a grass allergy comes into contact with these substances, their immune system overreacts, leading to an allergic reaction.

Grass allergies can be seasonal, with symptoms typically occurring during the spring and summer months when grasses are actively growing and releasing pollen. However, some dogs may experience year-round symptoms if they are allergic to indoor grasses or other allergens such as dust mites or mold.

What Breeds of Dogs are More Likely to Be Allergic to Grass?

Certain breeds of dogs are also more prone to developing grass allergies, including terriers, retrievers, and bulldogs. Additionally, dogs with a history of allergies or other allergic conditions, such as food allergies or atopic dermatitis, may be more likely to develop grass allergies.

How Veterinarians Diagnose Grass Allergies in Dogs

To diagnose grass allergies in dogs, veterinarians will typically perform a physical examination and take a detailed medical history. They will also look for characteristic signs of grass allergies, such as skin irritation, redness, itching, and hair loss.

Allergy Testing

In some cases, veterinarians may also perform allergy testing to confirm the diagnosis. Allergy testing can include skin tests or blood tests to identify the specific allergen causing your dog's symptoms. Skin tests involve injecting a small amount of allergen under the skin and observing the dog's reaction. Blood tests, on the other hand, measure the levels of antibodies to various allergens in the dog's blood.

Elimination Diets

Elimination diets may also be used to determine if a dog has a food allergy that may be contributing to its symptoms. In this case, the dog is placed on a strict diet that avoids common allergenic ingredients, and their symptoms are monitored to see if they improve.

Treatment of Grass Allergies in Dogs

Hypo-Allergenic Shampoos

These can help soothe and moisturize the skin, and reduce itching and inflammation. They typically contain ingredients like oatmeal, aloe vera, chamomile, rosemary, and hydrocortisone.

Natural ingredients: a special formula consisting of chamomile, rosemary, bitter ginseng, and coconut oil, which facilitates the removal of odors and relieves itchy skin.

Supplements

Omega-3 fatty acids and probiotics may help reduce inflammation and support your dog's immune system.

Medication

Medications can help reduce your dog's symptoms and include:

Oral Medication

These can help reduce itching and other allergy symptoms. Common antihistamines used in dogs include diphenhydramine (Benadryl), cetirizine (Zyrtec), chlorpheniramine maleate, and fexofenadine (Allegra). In particular, paracetamol maleate, a first-generation antihistamine, is effective in targeting anti-allergic symptoms.

But Chlorpheniramine Maleate tablets are forbidden for dogs/cats less than 3 months old.

Topical Medication

Zinc Oxide

• Anti-itch: Zinc oxide can relieve itchy skin caused by allergies and external irritants when applied to the local skin surface, and has an anti-itch effect.
• Antibacterial: Zinc oxide can inhibit the damage caused by bacteria such as Staphylococcus aureus and Pseudomonas aeruginosa to the skin.

Antibacterial Spray

• Kills more than 650 kinds of bacteria and fungi in minutes.
• Penetrate 2mm subcutaneously for antibacterial purposes.
• Good for wound healing, skin renewing, and itching relief, having great antibacterial and anti-inflammatory effects.
• Nano-silver particles are applied with slow-release technology.

Natural Treatments

Natural treatments for a serious reaction to grass allergies in dogs, like oatmeal, will relieve a dog's itchiness.

Immunotherapy

Immunotherapy, also known as allergy shots, can help desensitize your dog to the grass allergen over time. This involves giving your dog small, gradually increasing doses of the allergen to help their immune system build up tolerance. Immunotherapy is typically recommended for dogs with severe or persistent allergies.

Prevention and Management of Grass Allergy in Dogs

Environmental Management

Reducing your dog's exposure to grasses and other outdoor allergens can help alleviate their symptoms. Some tips include:

• Keeping your dog indoors during peak allergy seasons
• Limiting outdoor time during the early morning and late afternoon when pollen counts are high
• Mowing the lawn frequently and keeping the grass short
• Cleaning your dog's paws and coat after they have been outside

FAQs

Can Dogs Be Allergic to Pollen?

Yes, dogs can be allergic to pollen, just like humans. Pollen is one of the most common allergens that affect dogs and can cause allergic reactions in dogs. Pollen allergy in dogs is commonly referred to as "seasonal allergies" or "hay fever," and it is more prevalent during the spring and summer months when plants are in bloom and pollen is prevalent in the air. Symptoms of pollen allergy in dogs may include itching, sneezing, runny nose, red and watery eyes, coughing, and respiratory distress. If you suspect that your dog is allergic to pollen, you should consult with your veterinarian for proper diagnosis and treatment.

What Do I Do If My Dog is Allergic to Grass?

If you suspect that your dog is allergic to grass, it's essential to take them to the veterinarian for a proper diagnosis. Your veterinarian can perform tests to determine if your dog has a grass allergy and develop a treatment plan to help manage their symptoms.

Here are some steps you can take if your dog is allergic to grass:

Minimize exposure to grass

Try to limit your dog's exposure to grass as much as possible. This can include keeping them on a leash during walks to avoid running in grassy areas and keeping them indoors during high pollen days.

Clean your dog's paws

When your dog comes inside from outside, wipe their paws with a damp cloth or use a paw wash to remove any pollen or grass that may have gotten stuck on their paws.

Bathe your dog regularly

Giving your dog a bath can help remove pollen and other allergens from their skin and coat. Your veterinarian may also recommend a medicated shampoo to help relieve skin irritation and itching caused by grass allergies.

Can Dogs Get Seasonal Allergies?

Yes, dogs can get seasonal allergies just like humans do. Seasonal allergies in dogs are usually caused by environmental allergens, such as pollen, mold spores, and dust mites. Dogs can also be allergic to certain foods, fleas, and other substances, but these types of allergies are not seasonal.

The symptoms of seasonal allergies in dogs can include itching, scratching, licking, chewing, and rubbing their face or body on furniture or carpet. Other signs may include red, inflamed skin, hair loss, ear infections, sneezing, and watery eyes. These symptoms can be uncomfortable and can affect your dog's quality of life, so it's important to seek veterinary care if you suspect your dog has seasonal allergies.
