I.G.
Dogs are pack animals, they need companionship. In addition your dog is just a puppy who has been seperated from his family to be with you. I would expect him to be whiny and clingy.
Please don't take this the wrong way, but I strongly, STRONGLY recommend that you sign yourself up for puppy classes NOW! In your post it seems like you do not have a lot of experience with dogs and this breed in particular. If you do not train your puppy correctly and consistently you WILL become very unhappy with it.
Poms can be quite strong minded and difficult to housebreak, they also tend to develop small dog syndrome (yappy and nippy) if not trained and exercised properly - not a pleasure to have around with small kids!
With proper training (mainly for you and your family) having a dog is an enjoyable experience, without - it can be a disaster.
Good luck.
