any guess on how big he will be?? - Page 4

Females are different.

They not only mature at a smaller size (obviously) but they grow at a different rate.

Females often hit half their final weight at 15 weeks, and some a little earlier.

Furthermore, they vary more than males.  Some females barely double their 15w weight, others double their 17w weight, but the latter is rare except for puppies kept very thin.

Often, the big female in the litter will be the size of the big male (around 13 lbs at 6 weeks).  That larger male will mature to 90 but that same-sized female will only mature to 75.  Those pups will be the same weight until around 3-4m old and only then will the male leave the growth curve and race ahead.  So you can't just double the 4m weight of the female.

A DDR female who was 42 lbs at 4m matured to 74.  Note that her 15w weight was 37.

Another DDR female (a Bodo Grafental gdaughter who went to Trafalgar and cleaned up in OB) was a huge 47 at 4m and matured to 85.  Her sire was the same weight at 4m, but matured to 100+.  Note that this female's 15w weight was 42.

Little females who are 30 at 4m mature to a weight in the 50s. At 15w they are usually in the high 20s.

Often, female pups are all similar until 3m and only then diverge.

Best to take a weight at 15w and double it for females.  If the puppy is under 30 lbs at 15w, and she is not starving, she is going to be even smaller than double this weight (subtract a pound or two).  If she is larger than 40, she may more than double this weight (add a pound or two).

Note that their earlier weights are not accurate for prediction.  And they often stop growing at different ages.

On a side note, I think there is an evolutionary explanation for the greater variety in females than males.  In females, there is a stiff tradeoff between maturing earlier and getting one extra litter in during a lifetime, or even attracting a male and forming an alpha pair bond versus maturing later and having a better chance of surviving well, protecting pups, and defending the alpha bond.,  In males, maturing early has no real advantage and just puts you at greater risk in the pack.   Think of the analogy in humans.  Young males were driven to find young females outside of the clan.  If they rushed right in, they'd get killed by the mature human males of the strange clan.  So they had to persist for a long time, waiting their chance in the bushes to "mate."  By this time, the young female has noticed the male and if she has reciprocated affection, she is coordinating strategy to meet.  This is the explanation evolutionary psychologists have for why our lustful crushes usually last 18 months -- we were selected to persist in first-time attraction for a long time while working out the getaway.  To the point (sorry) the young male who matured too young would be at a much greater risk if he tried this, so most males matured about 18 months before they were capable of defending themselves.  The female could not, even at maturity, prevent violence from mature males, so the female of our species had no size-advantage to waiting.  Only aggression-advantage vis-a-vis other females. 

Thanks so much MVF.  Makes complete sense.  I appreciate the time you took to answer my question thoroughly.

Harley, what camera is that? Sonys are great, but if you're new to them, they take a little figuring. I bet you don't have it set right. PM me and I can probably help. I have had 2; they don't operate like most of the others (Nikon, Canon, etc.) but they're great. I took 99.9% of all of Caleb's (and all the others) w/a Sony DSC F717. Loved it....wish it hadn't died after 6 years of faithful service.  Sorry for the sidetrack, but I bet I can help you get that thing taking calendar-quality shots of your pups.

MVF, Care to guess how much my female (DDR/Czech lines) will weigh as an adult? She was: 28 lbs at 14 weeks, 34 lbs at 16 weeks, 41 lbs at 18 weeks. (So I would imaging she was between the weights given when she was 15 and 17 weeks.) She was never fat. She just turned 11 months and was 63 lbs 2 weeks ago. (I wish I could post a pic but the board won't let me.)

Kelly -- you're welcome. My pleasure.
