Re: 6month puppy weight
I think it's probably not a good idea to compare puppies. As you've noted, they're built differently and come from different genetic stock. So, they'll be different.
The rule of thumb is that you should see a hint of rib, and when you run your hand down their back, you should feel the spine (and hips), but there should be some "padding" so your hand runs smoothly. And, looking down on them, you should see that space in front of their hips to the chest, it should have the shape in the pic.
Also..and I'm about to make a sweeping over generalization based just on my own experience, so hold onto something sturdy.......most of the V's in the wild I've seen..and frankly, most dogs in general...are obese. So, they lack shape, making a "Normal" pointer look skinny.
You should ask your vet the next time you see him/her, she might be able to give you a more definitive answer based on an exam. But from here, she looks reasonably OK.
