How did you come to this conclusion? The treatment appears intended to be given over the lifespan of the animal and not just during adolescence (not sure when you would start this therapy).
The very fine article suggests that over production of this hormone causes accelerated aging over the lifespan of the animal, I didnt go through exhaustively but I saw no indication that the drug was intended to make dogs smaller.
