Symptoms of grass allergies in dogs can vary but often include red, watery eyes, bald patches of fur, coughing, sneezing, and itchy or irritated skin. While these symptoms may resemble other health issues, such as fleas or mange, they could indicate an allergic reaction to grass. Recognizing these symptoms early allows pet owners to seek appropriate treatment and explore alternative solutions, such as artificial grass, to minimize their dog’s exposure to allergens.
