Havanese dog: tips, experience, and stories about this dog.?

We are getting a Havanese puppy in July. We are so excited!!! I am 14 and i have a 8 year old brother and a 12 year old sister. We are getting the dog from a breeder in Lafayette, Louisiana. We live in Pass Christian MS so it is not far away. The breeder has been breeding for a very long time and she has taught her latest litter (including or puppy) how to behave and he is even pottytrained!!!!! We are probobly going to name him Napoleon. He is a chocolate havanese puppy with white markings. His brothers are red and one is black. His mom is dark brown and his dad is brown with white markings like him. I just wanted to know if anyone has a Havanese and how you like it and whats it like living with one. Also if you have any tips on them i would love to hear those. Thank you!
