My two male dogs fight. Is unneutered status causing aggression?

Updated On September 23rd, 2025

Pet's info: Dog | American Pit Bull Terrier | Male | neutered | 3 years and 6 months old | 65 lbs

I have a three year old male red nose pitbul who is nurtured and a now 11 month old male brindle pitbul. They use to get along great , until one day they broke out in a fight. After that day it became almost constant so now we have to keep them separated and bought muzzles for both dogs. The older one is very particular on what dogs he likes and plays with but he is starting the fights, I'm suspecting because we have not got the younger one nurtured is this common?

It is possible that your younger dog being unneutered may be contributing to the aggression between the two of them. I would also try to think of the situations in which they have fought to see if there are any toys or other resources that they may be protective of. Consulting with a veterinarian or behaviorist may be indicated to determine the best way to move forward with both of them.
