Molly is a little overweight! It has been SOOO hot so we don't really get to play or go for a walk. The only time to go out is at night or in the morning but that is when the mosquitos are out. It is in the HIGH 90's or low 100's so it is hot. Astra is fit because she runs in the backyard everynight even tho there are mosquitos. Prince is a in the middle he is fit but overweight at the same time. He is one pound overweight. He is not too active but he still plays pretty good.
