I am almost positive that my Tilly is Pregnant by 1 week. Her appetite has increased and she is tired a lot. I read online to free feed a Yorkie and another place not to overfeed them in the earlier stage of pregnancy. I am confused what to do. I have always just feed here as much as she wants because she never ate more than 1/2 cup a day, now she is eating about 2/3 of a cup. Also should I change her diet or give her supplements during her pregnancy?
