KayAnn, I can only speak of my Goldens when it comes to finishing the "puppy stage". My Cocker, Kaycee, was 7 years old when I adopted her, and she was way past those bad years.

Honey is mostly mature now, and she will be 3 years old in December! But...she still has her moments with chewing things she isn't supposed to. I think it is more a symptom now of "I want your attention NOW, Mom" than puppy badness.

And Lilly, she just does whatever Honey does, if Honey is nearby. But for the most part, she's my "little old lady", but happens to be the youngest of my dogs and cats, at 2 1/2 years old!
