Your Papillon will quit growing in heights at 7-8 months.
But that does not mean he will not change anymore. He will "fill in"; grow stronger muscles, his weight will change -hopefully through muscle gain and not fat!!!
He will grow his adult hair coat now, it's just setting in.
And you will see some fringe development on his ears. (That alone is a different chapter)
