I didn't make time to weigh in the other day, but what a handsome, studly dude!
Boy that musculature in the shot where he's up on the wall! I mean, muscles bulging on either side of his spine! He's got the "lat" action goin' on the side there, it looks like.
So yeah, I agree: Not fat, but I do get an overall sense of, like, weighed down. Anyway, I'm really more complimenting you on him than anything.
My first Dobe was 28 1/2" and topped out at 96 lbs. and no fat to be found. Like LifeOfRubie said above, my guy had a sort of BYB build He was somewhat stocky and had a fairly wide head, His chest was kind of shallow, and he didn't have any (as the standard refers to it) "exaggeration of muscle or bone." I'd say that if my boy had a nice deep chest like yours, and was in the hard shape he always was in, he would have weighed 105-108.
The interesting thing is that your guy there may keep maturing physically and filling out some more for the next year– year and a half!
