dogs in thw house?

We keep 100lb plus dog in the house. Let me first say that I'm very funny about smells in my house. He is 100% house broke, gets a bath regularly with dawn ( because their body oils smell), I wash his bedding regularly, and besides the regular vaccuming, mopping, and dusting, I air the house out frequently. He has been in the house for over a year and so far we don't have a problem with dog odor. Having him in the house requires extra work and effort but he is so worth it. I sleep just fine at night when my husband is working nights knowing that he would maul anyone who enters our house uninvited. Best security system ever.
