Our Wendy was 2# 12 oz at 8 wks
7# 12 oz at 12ks (so a pound a week)
9 # 6 oz at 15 wks. The vet agreed she was great. Perhaps the female is smaller, too.
We have had Wendy on Buffalo Blue Puppy brand eating twice/day. For training, we use carrots, apples, as tiny pieces. The vet said she looked great at 9# 6 oz at 15 wks old; was only 2 # 12 oz at 8 wks old.
