My family will be pleased I've found others to talk with about my dogs

Hi, everyone will be glad I am on this site! We have just gotton a female 10 wk old berner and I am so in love! We can actually see her grow. She gained 4 1/2 lbs in one week! She gets taller and smarter and then all of a sudden, stubborn!! But who can resist those eyes? How old in your berner? What do you feed and any puppy health issues?
