How fortunate of you to be able to have a breeder in your family! You have a wonderful life source for your puppy! I will be difficult (I'm learning myself! I've had my little boy for week now!) but you will enjoy the learning experiences. When you see them do good things it just warms your heart! I don't have children, but I'm sure this is what it feels like.
Best wishes to you and if you have questions YT is the best place to ask! Everyone here is very friendly and not so judgmental!
