I need help on trying to house train my dog!

[staceyh24]

Hi, My Dog Lucky is about a year and a half years old and still not house trained! I'm not sure what I am doing wrong but she wont pee or pooh in the house when I am home, But when I go out she will pee everywhere! I put her out before I go out so she doen't need to pee. But as soon as I leave the house even for just one second to go nextdoor I will come home to pee either on the carpet or she will pee on my bed! Sometimes she even pees on people! My son was sitting on the floor watching T.V and she came over and crouched on him and peed! I'm not sure what to do, do anyone have any suggestions?
