I saw nothing in any of the quoted articles that says it is more important in larger breeds? Please correct me if i did not read it rightly. The point they make is that hormones affect bones and other parts of the growing dog, and that neutering an immature dog can have bad effects as well as good. If the neuter can be put off until maturity, it can be more of a win win situation.
Although it is agreed that breeding a three pound dog has dangers, interfering with body development, and anesthesia also have dangers and consequences. All I'm saying is that one should be aware of all known facts when making this decision.
