Just understand that "ruining dogs" is a sore spot to most long-term folks, who have watched so many truly wonderful dogs get destroyed by so many young, reckless owners ... that it makes it hard not to get angry when we see this kind of thing happening again. There are simply reasons why professionals learn to avoid doing certain things, and it makes no sense to violate these basic rules (good feed, allowing to mature, etc.).
Remember, "You can never break The Rules; you can only break yourself (or your dogs) against The Rules."
Even if you appear to "get by" a rule and bend it a bit, it will be a very short-lived and fleeting victory. Ultimately, the hens will come home to roost. At the end of the day, you and your dogs will eventually reap the results of that habits that you sow ... and it's as simple as this:
Good habits, repeated over time, will give GOOD long-term results.
Bad habits, repeated over time, will give BAD long-term results.
It really is as simple as that.
And what you've described with the handling of this young gyp are BAD habits to get into, nothing more. That is what we all are trying to communicate to you, so you might want to just accept this fact and stop trying to justify it.
Good luck,
