My neutered male dogs fought. Will they fight less now that they're older?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Male | neutered | 2 years and 3 months old | 100 lbs

Hey, I’m tired of seeing my dogs on chains and I can’t really put them in the house (no room). I was thinking about getting shock collars & underground fence for all of them. I have two boys and girl. The only thing I’m worried about is the two boys fighting. When they were puppies they fought a lot that’s why I separated them. Do you think since they’re older and neutered they’ll be less likely to fight? They’re 2.5 yrs old. I want to keep all of them together without them killing each other.

It's possible that the dogs could get along better now that they are older or it might be worse. You should probably start with a slow introduction and see how they behave around each other. If there are any signs of aggression at all they should be separated again. You could also look into building a dog run or fenced pen so they can be outside separately.
