My GSD male is 6 1/2 months old and very well behaved. I have always neutered other males I’ve owned by this age but after research I have decided not to neuter Klaus until he is a year old or more and then maybe never. I just want to know what behavior to expect as he is maturing and what problems I need to head off at the pass, so to speak. This is my first GSD and there is def a learning curve! Lol! He keeps me on my toes as it is. Any advice or suggestions is welcome.
