Every day she pees and poops in house!!!

Question
Eight mths ago we rescued a lab/bloodhound or lab/boxer mix,Vets thinks she 2yrs old now.She was fixed 2 mths ago. She uses the bathroom outside when we take her out.Only put food out in afternoon for 30 min. BUT, we take her out twice in morning , when I get up and right before I leave .I work only 5 1/2 hours(gone only 6). And everyday I come home she has peed and pooped in the house, EVERYDAY????. If I'm  home she will go all day without a accident. If am gone more than a hour, I come home to mess. Even if we take her out and she does both ... I tried crating her when I am gone,she works herself up so bad she sheds , throat is horse, (neighbor complains that she barks the whole time)then panics when it is time to get her out, making hard to get her on leash to go out. WE even leave the TV on for company (that mostly for our cats and terri/mix , they are use to us doing that for them). We got rid of carpet and put wood down and that did not stop her either. She is such a loving,cute , large ,lazy dog. Even if I go down the street for 10min, she acts like I have been gone forever, almost knocking grandchild out of my hands. I really hate the thought of giving her up. My family and I love her but, maybe she is not meant to be a indoor dog.I really think I may have to give her up?? Any ideas...

Answer
She simply isn't house trained, and it sounds like she may have the beginnings of separation anxiety, or at least is somewhat claustrophobic.  It may be that she is so anxious when you leave that she can't control her bodily functions (ever notice how you have to pee sometimes when you get nervous?)  That's part of the natural fight or flight mechanism.  The fact that when you are home she doesn't eliminate tells me that someone may have scolded her for her indoor accidents - therefore, she's afraid to eliminate in the presence of a human while she is indoors.  When you leave, she has no reason to fear.  Of course, if you look cross when you come in and see that she has had an accident, you may be contributing to her nervousness.  If this were my dog, I would try containing her in one room, rather than crate her.  There are two really good little booklets that discuss these subjects at length, and they aren't terribly expensive:
"I'll Be Home Soon" and "Way to Go" both by Patricia McConnell.  You should be able to get them on Amazon.
