I am in the same position as you as me and my husband both work. We got Romeo at 11 weeks and it was out of the question to even leave him home by himself. I took him to work for a while, then my husband took him to his job for a while. Then overtime we started leaving him for 30 min here and there and he would cry his heart out

He was not having it...We really wanted to be able to leave him at home since it was the safest place for him. I looked into doggy day care but it would've added to our bills. So now I come home every so often at lunch time to check up on him. I like the idea of leaving the TV on, especially animal planet or something, but it wouldn't work for us because our TV is in our closet and he would get himself into a whole lot of trouble!! I know they also have music CDs you can get for them to calm them down, as another YTer suggested.
Romeo still doesn't like it but we have to work to be able to have him. When we get home, we spend a lot of time with him to try to make up for the time we couldnt be there for him.
Good luck to you and keep us updated about Carmen
