I have heard of some joint health risks for large breed puppies if they are neutered before 6 months, but I don’t think I’ve heard of any after that. I know more about it for female dogs, but I’ve never heard of anything wrong with neutering after 6 months for LBPs.
However, as someone who has volunteered in animal rescue, I definitely think you should neuter your dog at some point. I have seen far too many cases of puppies ending up in shelters due to people not spaying and neutering. Yes, it is more of a problem with owners that are irresponsible, and you are certainly responsible if you are asking this question, but anything can happen to any dog.
