Rapedoll and Fucktoy are very good.

If you want to know the story centers around a slave girl who really truly loves her master with all her heart and soul. The other slaves he owns are back stabbing and disobedient. She tries her best to win her master's love. She is treated pretty much the same as a dog, while the other girls are treated like people. I've thought of just calling her dogslut or dogslave. She is the most degraded and dehumanized and abused slave in their home, but she loves every moment of it.

And if you have more names please write them down. Not just dog names (that part of the story really isn't for sure) but anything you can think of. Great ideas!
