We're getting a lhasapoo puppy!!! And I'm nervous...

Let me give you some history...We have always wanted a dog, we have tried the shelter many times only to end up returning the dog because it just didn't work out once we got home for one reason or another from the dog trying to kill our cat to the dog having issues with my daughter. Anyway after all the failing attempts to adopt we decided to go to a breeder. Now we are expecting a Lhasa poo puppy in two weeks. He will be 10 weeks then. But now that we are getting a puppy and I feel pretty confident that we can make this work I'm nervous because of all the dogs we have tried so hard to have as a part of our family and maybe I'm wrong and something else will go wrong.

I'm hoping that maybe someone can give me some sort of advice from potty training to good toys to buy to maybe even people who own Lhasa poos and what their dogs are like and what worked for them with training them. I am totally open to anything since this is our first shot at a puppy. Maybe this way I won't feel so lost when he gets here.
