I have a dog in my house, I get the carpet cleaning company steam clean my carpets once a month, but the house still does not smell good.the fragnance lasts like 3 days and the house smells like dog again.I tried sprays, fragnence outlets, candles you name it.some people I know have pets but their house smells really good all the time,and I am so shy to ask them whay they do to keep nice smell in their house, what can i do for permanent nice smell.
