Just got a response from Remy's Mom and Peaches Mom too. (Thanks so much!)
Remy is 20lbs and 16 in. tall!
Peaches is 15 -18 lbs. 18 inches tall to top of head.
Bella is 16 lbs and 18 inches tall.
Conclusion: When the puppies went home at 8 weeks, Bella was the smallest of the litter and Remy was the largest pup in the litter. So the weight range of 16 - 20 lbs is a good estimate for the size of this litter.
This years litter might have a smaller weight range since our stud is a little shorter than last years stud, (by a few inches)
