Anxiety In Dogs

My Dog, Lulu, Suffers From Anxiety When She Is Left Alone In The House. She Tends To Tear Up The Carpet, Sofa, Etc. She Is Also Extremely Excited When We Come Home.

Other Than More Exercise When We ARE Around, What Other Measures Can We Take To Help Her? Is There Anyway To Keep Her Occupied While We Are Gone? We Leave The TV On Sometimes Which Helps A Little, But If We Are Gone Too Long She Will Get Antsy.

Thanks!
