Similar to humans, the puppies are moving from the cute (they're still cute) to an awkward looking stage. This is to say that in human terms, it's the adolescent times where the proportions are not uniform.
We are steeling ourselves for the puppies. As a sign of transitioning, we are noticing that the ears are moving from a folded state to the vertical state. Also, their barks are not as quiet and sharp but a bit louder and more urgent sounding. It's sort of like teen boys' voice changing. Total awkwardness is not there yet but it's coming.
