Thank you for posting this question. The current recommendation is to wait until these large and giant breed dogs are skeletally mature prior to neutering. This occurs somewhere between 12-18 months depending on the size /breed of dog. This is thought to help limit the amount of arthritic change as they age. Thank you for using Pet Coach.

This is one of those controversies in veterinary medicine right now. You ask 10 vets you are likely to get 7-8 different answers (opinions).
My personal opinion is to wait until he is at least 18 months old to have him neutered. There have been some studies done that show that early neutering in large breed dogs may cause laxity in tendons/ligaments which may increase the chances of cruciate ligament tears in the knees later in life. My only caveat to that 18 month rule is if the dog is having behaviorial issues. In those cases I would neuter sooner.
Hope this helps. Best wishes.
