Causes
Grass pollen allergies in dogs are part of a broader category of allergies known as atopic dermatitis. This disorder is caused by an abnormal immune responseAn immune response is the immune system's reaction to foreign substances (antigens), such as microorganisms or proteins. It involves a series of processes aimed at recognizing, fighting, and eliminating these antigens. to environmental allergens. The most common environmental allergens include pollen, house dust mites, and mold.
A dog’s immune systemThe immune system is the body's defense system against infectious agents such as bacteria, viruses, fungi, and parasites. It comprises a complex network of organs, cells, and molecules that work together to protect the body. recognizes grass pollen as harmful invaders, even though they are actually harmless. This misinterpretation leads to an excessive immune responseAn immune response is the immune system's reaction to foreign substances (antigens), such as microorganisms or proteins. It involves a series of processes aimed at recognizing, fighting, and eliminating these antigens., in which the body releases histamines and other inflammatory substances. These substances are responsible for the typical allergyAn allergy is an overreaction of the immune system to a normally harmless substance, the allergen. The reaction can include symptoms such as skin rash, itching, sneezing, respiratory distress, or in severe cases, anaphylactic shock. symptoms such as itching and inflammatory conditions.
Genetic predispositionA predisposition is an innate inclination or susceptibility of an organism to certain diseases or conditions. In dogs and cats, there may be a genetic predisposition to certain conditions such as hip dysplasia or certain heart diseases. plays a significant role in the development of allergies. Certain breeds, including the Labrador Retriever, Golden Retriever, Boxer, and various terrier species, are known to be more susceptible to developing allergies. Studies suggest that genetic factors can affect the barrier function of the skin, leading to an increased risk of developing atopic dermatitis.
Environmental factors and the season also influence the occurrence of grass pollen allergies. During the flowering season of grasses, which can vary by region, the pollen in the air is most common, which is associated with an increase in allergyAn allergy is an overreaction of the immune system to a normally harmless substance, the allergen. The reaction can include symptoms such as skin rash, itching, sneezing, respiratory distress, or in severe cases, anaphylactic shock. symptoms in sensitive dogs.
Symptoms
The most common symptoms of a grass pollen allergyAn allergy is an overreaction of the immune system to a normally harmless substance, the allergen. The reaction can include symptoms such as skin rash, itching, sneezing, respiratory distress, or in severe cases, anaphylactic shock. in dogs are skin problems, which are noticeable through intense itching, redness, and skin rashes. Dogs often scratch or bite their skin, which can lead to secondary skin infections.
Ear infections are also a typical symptom. Dogs with allergies tend to develop recurrentRecurrent refers to a disease that repeatedly returns or worsens after a temporary remission or improvement. ear infections, which are characterized by redness, swelling, and discharge from the ear canal. This can lead to considerable discomfort and pain.
Some dogs also show respiratoryRespiratory refers to breathing or the process of breathing. Respiratory diseases affect the respiratory tract and can impair the ability to breathe effectively. symptoms, although this is less common. These include sneezing, cough and increased nasalNasal refers to the nose and nasal cavities. In veterinary medicine, this can involve examinations, treatments, or diseases affecting the nose of dogs and cats. discharge. These symptoms are similar to those of hay fever in humans.
Long-term untreated allergies can lead to skin thickening and darkening (hyperpigmentationHyperpigmentation is a skin condition in which certain areas of the skin become darker than the surrounding skin. This can be caused by an overproduction of melanin, sun exposure, inflammatory conditions, or other factors.). ChronicChronic refers to a condition or disease that is long-lasting or permanent. Chronic diseases often develop slowly and can lead to persistent or recurring health problems over time. skin irritation can significantly impair the dog’s quality of life and lead to behavioral changes such as irritability or Apathy.

Prevention
The preventionPrevention includes measures taken to prevent diseases or injuries. In veterinary medicine, this includes vaccinations, parasite control, and health monitoring. of grass pollen allergies is challenging because it is difficult to completely avoid exposure to pollen. Nevertheless, some measures can be taken to reduce the risk and severity of symptoms.
It is recommended to avoid walks during times of high pollen concentration, such as early morning or late afternoon, and to clean the dog’s paws and coat after being outdoors to remove pollen.
A balanced diet and the use of supplements containing omega-3 and omega-6 fatty acids can support skin health and reduce the body’s inflammatory response.
Regular maintenance and cleaning of the living environment, including frequent vacuuming and replacement of air filters, can reduce the amount of allergens in the house and thus minimize the risk of allergyAn allergy is an overreaction of the immune system to a normally harmless substance, the allergen.

Outlook on current research
Grass pollen allergyAn allergy is an overreaction of the immune system to a normally harmless substance, the allergen. The reaction can include symptoms such as skin rash, itching, sneezing, respiratory distress, or in severe cases, anaphylactic shock. in dogs, also known as atopic dermatitis, is a complex and increasingly researched field in veterinary medicine. In recent years, scientists have made significant advances in understanding the genetic and immunological mechanisms underlying this disease. It is believed that certain genetic predispositions make dogs more susceptible to environmental allergens such as grass pollen. The genome of various dog breeds is being intensively studied to identify specific genetic markers associated with an increased susceptibility to pollen allergies.
Current research also focuses on the role of the skin and gut microbiome in the development and management of allergies. Studies have shown that an imbalanceImbalance refers to an imbalance or disruption of normal function or composition in the body, which can lead to health problems. of microorganisms on the skin surface can impair the skin’s barrier function, potentially leading to increased sensitization to environmental allergens. Manipulation of the microbiome through probiotics or prebiotics could be a promising addition to conventional allergyAn allergy is an overreaction of the immune system to a normally harmless substance, the allergen.

Therapies can be medicinal, surgical, or through other medical interventions. in the future.
Another significant area of research is the development of new diagnostic techniques to better identify pollen allergies. Currently, serological tests and skin tests are used to diagnose grass pollen allergies, but they are not always accurate. Researchers are working on the development of molecular allergyAn allergy is an overreaction of the immune system to a normally harmless substance, the allergen. The reaction can include symptoms such as skin rash, itching, sneezing, respiratory distress, or in severe cases, anaphylactic shock. tests that can provide more specific and individualized results. These tests could make it possible to identify the exact type of allergenAn allergen is a substance that can trigger an allergic reaction in sensitized individuals. These reactions vary in intensity and can range from mild symptoms to severe, life-threatening conditions. to which a dog is reacting, which could lead to more targeted and effective treatment strategies.
In the treatment of grass pollen allergies in dogs, immunotherapy is considered a promising option. SubcutaneousSubcutaneous means "under the skin." In medicine, it refers to the administration of drugs or the placement of implants directly under the skin. immunotherapy (SCIT) and sublingual immunotherapy (SLIT) are already being used successfully for desensitizationDesensitization is a treatment procedure that aims to reduce an animal's sensitivity to an allergen. This is done through gradual exposure to the allergen in controlled doses to build tolerance. to specific allergens. Current studies are investigating the optimization of these therapies to increase the success rate and shorten the treatment duration. New formulations and combinations of allergens are being tested to cover a broader range of allergic reactions.
In addition, research has led to the development of new pharmacological treatments. New antihistaminesAntihistamines are medications that block the effects of histamine in the body, thereby alleviating allergic reactions. They are used in dogs and cats to treat Itching, Skin inflammation, and other allergy symptoms., immunomodulatorsImmunomodulators are substances that affect the immune system by increasing or decreasing its activity. They are used in dogs and cats to treat autoimmune diseases, allergies, or as cancer therapy., and anti-inflammatory drugsAnti-inflammatory drugs are medications that reduce inflammation. They can be divided into nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids and are used in dogs and cats to reduce Inflammatory conditions and Pain. are being developed and tested. These drugs aim to relieve symptoms and improve the quality of life of dogs with pollen allergies. The discovery of monoclonal antibodies that block specific inflammatory mediators represents a significant advance in drug treatment.
The research results of recent years give reason to hope that the treatment of grass pollen allergies in dogs can be made even more effective and individualized in the future. By combining genetic, microbial, and immunological insights with advanced diagnostic and therapeutic approaches, the aim is to significantly reduce the disease burden for affected animals and their owners.
