Keeping your dog clean with regular brushing, bathing, and wiping off paws after walks can help reduce the number of allergens in the environment and reduce the chances of your dog licking or scratching, which can release more dander. Regular vacuuming and mopping of floors, lint-rolling of furniture, and using air purifiers can also help cut down on allergens around the home.Keeping your dog clean with regular brushing, bathing, and wiping off paws after walks can help reduce the number of allergens in the environment and reduce the chances of your dog licking or scratching, which can release more dander.
