If I'm converting it right, that would be 83.6 lbs for your boy and 58.3 lbs for your girl (1 Kilogram = 2.2 Pounds). At ten months, that's maybe a little big for your boy, probably right on track for your girl, but usually by ten months, most of their rapid growth is past. You can probably expect another 10-15 lbs as they put on their adult muscle and build--so that would be about 93 lbs (42 kg) for the boy and 68 lbs (31 kg) for the girl--really just about right for a couple of heavy boned dobes.
Different bloodlines, of course, tend to mature at different rates--maybe you can ask your breeder about how your dogs' bloodline develops. And really what matters is whether they are a good weight for their own individual bodies. You should be able to see the last couple of ribs, feel the rest easily with no fat layer, see a noticeable tuck-up of the belly, and a "waist" just in front of the hips from above. Keeping them the right weight for their bodies means better agility and speed from them, less stress on their joints, ligaments and muscles, and just all-around better health.
Well.......that is on the heavy side......but it can be hard to tell with an individual dog when the bulk of his growing is done. My current male had pretty much put on most of his weight by 9 months, though he is on the smaller side.
If you just concentrate on keeping their weight matching their frames, they will grow to whatever size their genetic makeup tells them to be, and that's about the best you can do.
