My male dog is hormonal and snapping. Will neutering help him calm?

Updated On September 23rd, 2025

Pet's info: Dog | Havanese | Male | unneutered | 1 year and 2 months old

Kiba seems to be literally hormonal. My mum is against neutering him and he's usually a very chill dog, but nowadays he's been very interested in the ladies and sometimes he snaps at male dogs. It's a new thing, he hasn't been aggressive and even now it's a rare thing. I've read about dog adolescence so I was wondering if he will calm down later.

It sounds like Kiba is entering the stage where is hormones are telling him to get all the lady dogs pregnant, and to keep away other male dogs. I would recommend neutering Kiba to keep him out of trouble. Fights with other male (and even female) dogs can turn ugly very quick. Neutering at this early age should prevent long-term aggression, but it can take 6-8 weeks for the hormones to completely leave his system. Unless you are planning to breed Kiba, there is no medical benefit to leaving his testicles in a this point. His chill personality should be locked in, and testosterone is no longer needed as he should be done growing at this point.
