My male dog growls at other males. Will neutering stop this behavior?

Updated On September 23rd, 2025

Pet's info: Dog | Chihuahua | Male | unneutered | 1 year and 4 months old | 4 lbs

We were thinking about breeding our 1.5 year-old male chihuahua (in the future), but since his little skittles dropped he's started growling at any other male dog that still has his balls. Will he stop doing that if we get him neutered?

Neutering will decrease testosterone levels which can in turn decrease chances of aggression, so any dog that is intact and is having aggression issues, neutering is recommended. That being said, sometimes the behavior becomes more of a habit and because of this, neutering isn't a 100% guarantee to fix the issue, but it is at least the first step.
