Hi and welcome to COL
I have an 8 month old Blue Roan Bitch called Skye, although we often refer to her as BabyBear.
I have however in the past had a male dog.....
I was advised to have him neutered to calm him down, as he was extremely boistrious. We did as we were advised and had him done and it worked a treat.
I cannnot tell you what to do with your boy especially if he is so good anyway but i'm sure someone with alot more experience than me will be along soon to advise you
