My young male dog is aggressive and protective. Will neutering help?

Updated On September 23rd, 2025

Pet's info: Dog | Miniature Pinscher | Male | unneutered | 5 months and 13 days old | 8 lbs

I have 2 litter mates, Mega & Radio. Mega is much bigger than Radio (he was the runt), and sometimes he can be extremely rough with him. They are 5 months (mini pins). Mega started becoming protective over me, & aggressive to others (puberty). The first time I noticed was when he charged at a visiting family member. Since then he tries to charge at neighbors. He's jealous when Radio play with toys or get attentions. Treats don't work with guest. Time outs aren't effective. Will neutering help?

Now is the best time to neuter them both. Neutered males are more docile and make better pets. When they reach sexual maturity at around 6 months and their hormones go into full swing so to speak, they may act aggressive toward other males and want to become dominant in the household. If you wait too long, neutering will not help. I suggest neutering all dog sin the house as soon as possible, then the hormones will die down in a few weeks. At this time, implement a training program with a trainer or by doing some research. The behavior will most likely get better, but that is not definite. Neutering with combined training is your best plan to change his behavior. .
