My Dachshund is 6 months old. Since we got him we have put in a play pen when it time for bed and when we are not home. We have a bed and chew toys in there for him. So far things are going okay. He does not cry when it's time for bed but sometimes he cries when he is the Pen and we are home. Someone told me that it is unhealthy to let the dog sleep in a different room from the owner. Is that true? Would it be better for the Dog to sleep in my bedroom while in the Pen? Or does it matter one way or the other.?
