"We now think that allergens are absorbed through the skin, not inhaled," Dr. Plant says, which means that frequent bathing can bring serious relief by washing away irritants. Look for shampoos with oatmeal and hydrocortisone, both proven anti-inflammatories, and try to bathe Bowser every 3 or 4 days.
Keeping your home free of dust mites and pollen can also help alleviate allergy symptoms. According to a study from the Netherlands, dust mite-sensitive dogs improved significantly when owners cleaned their homes using products specially formulated to remove those triggers. Try vacuuming regularly, installing high efficiency particulate air (HEPA) filters ($50 to $200), replacing old dog beds, and covering pillows and mattresses with allergy-proof cases.
