Cole will be 4 in May and he's been filling out for the past year. It's slowed down a lot, tho, so I think he's all grown now...or just about. However, in the past 6 months he's finally been getting his full coat.
He reached his full height at around 3 years. But after 12 mos there were only slight differences intermittently...which added up to about an inch and a half between 1 and 3 yrs of age. I do remember that at the age of 2 yrs 7 mos, he was higher in the rear again, and leveled out a couple of weeks later.
At a year he was 133 lbs, at two he was 145 lbs and at three and a half...155-157...which is right about where he stays. His line isn't large, yet he and his half brother, Katie Sidesinger's Mojo, are larger than the others in their lines. Those two got the "big" gene somewhere. LOL So just because the lines are smaller, doesn't mean there won't be one or two that pick up a gene from WAY back and surprise everyone.
Frankie is 11 mos (will be 1 in May), and even tho he's almost as tall as Cole, he's definitely MUCH more slender, and just gangly. It doesn't show in the pics, but it shows when he's wet. He has a "bigger" coat, so tends to look larger than he really is. His head's huge, and his bone is heavy ... so he's got a lot of growing to do yet. He weighs about 137ish right now. I suspect he'll be taller and larger than Cole is. He comes from larger lines.
