No breeding here either & my soon to be 3 year old male is intact. This is my first dog so I have nothing to compare him against other than neutered males in classes we have attended.
The only thing that really stands out to me is alot of neutered males seem to not care for my boy. My trainer said she has seen that often with neutered males against intact ones. Not sure if there's any weight in the statment.
I think the decision to neuter is a personal choice...alot of things to consider.
Sorry, I didn't realize your question was in the Schutzhund section. I read posts by "new posts"
