Yes these little ones are very close to us and we love keeping in touch with them as they adventure out into the world with their new owners.
We can understand your concern about adding another little one to your home. In our experience it is in the end excepted with open arms, but ultimately it is all on how consistent you are in the meetings. If it is done over a month ( which is easy to do with a puppy, because they should be restricted to a room or very small space while they get us to you and you to them. Also easier to potty train them.) with a few minutes each day slowly increasing it each week. This is best done after you have exercised the one or ones you've already had. Then you have to remember that it is you that is in charge and if you take that roll from the beginning it will be much easier on everyone and it will go much smoother. Remember, dogs are use to being in a "pack" and having more than one around is very normal. It is us that has continued to changed that normal behavior in them. It is not as hard to do as you would think too add ones to the family when you do it slowly, it usually goes pretty smooth. Again, if you are consistent.
