Plants begin to pollinate intensively, and the air becomes filled with increasing amounts of allergens such as grass, tree, and weed pollen. During this period, many pet owners notice the first signs of seasonal allergies. In sensitive animals, the immune system overreacts to these substances, treating them as a threat. This leads to inflammation, itching, and skin problems. Symptoms may persist throughout the entire pollen season and gradually become more severe. **Symptoms of allergies in dogs and cats – how to recognize them** **Allergy symptoms in dogs** - intense scratching and biting of the skin - licking paws, especially between the toes - redness and skin irritation - recurring ear infections - thinning coat - so-called “hot spots” (acute inflamed skin lesions) **Allergy symptoms in cats** - excessive grooming and licking of fur - small scabs on the skin - thinning coat - scratching around the head and neck - restlessness and irritability It is important to remember that allergies in dogs and cats are most often skin-related, which makes them easy to confuse with other dermatological conditions. **Where do seasonal allergies come from?** Most often, the symptoms are triggered by environmental allergens present in the animal’s surroundings. In spring and summer, their concentration is particularly high, which leads to an increase in allergic reactions. The most common factors include grass and tree pollen, weeds such as mugwort, as well as mold spores. Additionally, dust and mites, which are found both outdoors and inside the home, can also have an impact. Contact with these substances leads to an overreaction of the immune system, resulting in chronic itching and skin inflammation. **How to recognize seasonal allergies in practice** One of the most characteristic features of seasonal allergies is their recurrence. Symptoms appear during the same periods each year and usually worsen as pollen levels increase in the air. Pet owners often notice that their pet’s skin condition deteriorates after walks, especially on dry and windy days. Typical signs also include excessive paw licking after returning home and recurring episodes of itching that happen every year. These observations are very important because they help distinguish seasonal allergies from food intolerances or skin infections. **Diet for allergies in dogs and cats – what is worth knowing?** Although diet does not eliminate the source of allergies, it can significantly support the animal’s body and help reduce symptoms. Proper nutrition mainly affects skin condition, immunity, and regeneration processes. Omega-3 and omega-6 fatty acids play an important role, as they support the skin’s natural protective barrier and help reduce inflammation. High-quality protein is also essential, as it supports tissue repair and the proper functioning of the body. More attention is also being given to gut health, as the microbiome has a direct impact on immunity. Ingredients supporting digestion, such as prebiotics and fiber, may indirectly reduce allergic reactions. **Daily care for dogs and cats with allergies** In addition to diet, daily care is extremely important. Regularly washing paws after walks helps remove pollen that may have settled on the skin. Brushing the coat also reduces the amount of allergens trapped in the fur. It is also worth keeping bedding clean and avoiding walks during peak pollen hours, especially on dry and windy days. These simple actions can significantly reduce symptoms and improve your pet’s comfort. **Belly Welly – support during allergy season** **Belly Welly** foods were developed with sensitive animals in mind, especially those prone to skin issues and allergic reactions during the seasonal pollen period. A properly balanced diet can support the condition of the skin and coat, help maintain a healthy immune system, and support the body during increased exposure to environmental allergens. Regular feeding of high-quality food is an important part of everyday nutritional prevention. **When to visit a veterinarian** If symptoms are severe, chronic, or do not improve despite care and dietary changes, a veterinary consultation is necessary. Warning signs include: - severe skin lesions and wounds - persistent itching - recurring ear infections - loss of appetite or general weakness **Summary** Seasonal allergies in dogs and cats are an increasingly common problem that can significantly affect an animal’s quality of life. It is essential not only to recognize the symptoms but also to take a comprehensive approach involving care, limiting allergen exposure, and proper nutrition. A well-chosen diet can genuinely support your pet’s body and help alleviate the effects of the pollen season, improving their comfort every day.
