How much should a female, 13wk old rottie pup weigh?

Anywhere's from 8-15 pounds.

My rotties were 11 and 9 pounds at there check up at 8 weeks so I am assuming not much more than that

Females follow moms in size and stature, males follow dads. No specific answer here, just as long as not bony NOR TOO FAT!

Okay we went to the vet Tuesday and they now weigh 19.5 and 18 pounds... I am starting to think they're too big. The have grown quite a bit but after reading the earlier post I am starting to think that my girls are too big. They are only 13 weeks old (14 on Saturday).
