Hi, I have a beautiful 13 month old Beagel, but I am paranoid my house smells. 2 of my children asked what the horrible smell was when they came in from school, and my sister commented on the doggy smell yest. I wash bedding, mop the floors etc all the time! I am thinking of getting an air purifier or dehumidifier, but don't know where to begin. Please help me make my home smell better.
