please help me get this stench out!

Hi , I'm a first time mom to be. I'm 9weeks and I don't know what cleaning supplies to use. I had a dog that I got rid of,but his smell (doggy odor/pee ) is still in the house. I can't stand the smell any more. I tried scrubbing the smell out but it didn't work. I'm feel really nauseous because of the smell. Is there anything that works to get the smell gone for good?please and thank you . I don't know what to do anymore 😔
