Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Oh my goodness, Dallas is adorable! There is no medical or protective effect, like in female dogs, to neutering male dogs right away. I tell clients that if the dog is showing aggression, dominant behavior or is marking in the house then neuter them sooner. Neutering male dogs before they are middle age will prevent some prostate conditions (BPH, prostatitis, prostatic abscesses) , perineal hernias, and perineal adenomas which are hormonally caused. Good luck!
