What are the benefits of neutering a male dog and does it change behavior?

Updated On September 23rd, 2025

Pet's info: Dog | Havanese | Male | unneutered | 5 months and 9 days old

What are some good arguments for fixing our pup? I would like to convince my mum but she's still on the fence about it. Do they change behaviour a lot

Castration will have the following benefits: No more icky discharge from the penis or prepuce, no incentive to roam and look for females, if the dog shows some aggression, castration will usually lessen aggressive behavior. A lot of entire males are constantly upset and excited if they smell females in heat ( and the smell can travel for a mile and more), No chance of making babies.
