We had two boys from the same litter, they did not share a bed, each liked their own spot. They played together as that is what they had come from, if that makes sense. A number of years later and we adopted an ex-breeder. No life experience, knew nothing about the outside world. She learnt from the two boys, without us realising just how much. Toys were alien and she wanted to play but didn't know how. I would say it took her a year to figure out what life was about, what she liked and didn't like. She loved being with them, became her own dog and settled beautifully, but it took time. That is the biggest thing you can do just now, is give your new addition space and time. Enjoy, it's a pleasure to watch them flourish.
