What age do dogs reach maturity(spl??)??

[sammy101]

Does anyone know when dogs reach maturity?? i want to have a idea of when Kodie will stop growing,but since he has some Rotti in him he should be getting more "Bulky" looking.
He is 1 year,2 months old.

He's probably done growing taller he will now just fill out a little more and look more adult like;)
