I have a 6 month old male English Mastiff (JAKE) who is 100 pounds. He is well proportioned and a good size at his age for his breed. I have to get him neutered and my vet said that anytime after 6 months is fine. The only thing is I heard is that if I neuter him too early, he might not grow to his full potential. His mom is 180 and pop is 220 lbs. Now I do not intend to let him get fat, I feed him a quality food (CANIDAE) and he gets plenty of exercise. He looks great but I do not want to stunt his growth. Does anyone have any advise as to what a good age to neuter him is?
