Well i wouldn't feel bad, as long as there's someone in the house she won't feel like she's alone. Plus they need to learn that they have to play by themselves sometimes. If your that concerned about her being by herself when your Bf goes back to work, you should get another Yorkie to keep her company

haha that's what I did. I felt the same way as you because I go to College and have more class some days rather than others and i did't want Ruby to get lonely, so i got Bella. Now they are best friends and I don't have to worry when i'm not here. When I come home they stop playing with eachother and want to play with me, so it works out great
