My girls (Angle and Ceci) are both from the same litter. They are 8 months old. Ceci weighs 4 lbs and Angle weighs 7.5 Lbs. They free feed on Innova puppy. It does not seem that one eats more than the other and are about the same height. I just tell Angle she is big boned LOL Angle is in the front of photo Ceci in back.
