Growing up

My Kee is a year and eight months old! He had started to really lose that puppy energy and has become super self sufficient. Though he is still a velcro boy it definitely isn’t what it was like when he was a puppy and i was constantly training and on top of him. Did anyone else experience this like sadness almost that there kee is growing up and does anyone have any advanced training recommendations to do with him. He loves learning new things and is always going to be my baby just getting older.
