My intact male dog fights other male dogs. How can I help him?

Updated On September 23rd, 2025

Pet's info: Dog | Staffordshire Bull Terrier | Male | unneutered | 3 years and 9 months old | 66 lbs

I have a rather dominant male, intact dog, He is a 3 year old , 30kg staffy. He’s fine with the family and at home but one big problem is when encountering other male dogs! If there is any stand off, there is almost always a fight. 9 times out of 10 he doesn’t make the 1st move but when it kicks off, he is the one doing the damage. I hate this happening and any advise to reduce his dominant urge would be greatly appreciated! Many thanks

I'm sorry you are dealing with this problem! The first thing to do is neuter Loki. His aggressive behaviors to other male dogs could be due to the hormones produced from being intact. Intact male dogs will fight to protect their territory and for females. Neutering him can help reduce the aggressive tendencies. After that is done, I recommend getting him in with a professional behavioral expert. I never recommend owners work with aggressive behaviors on their own due to the serious risks to safety, and it is something that is best left to the professionals. A behavioral expert can work with Loki and you on his aggression, and can help train him to reduce it. Good luck, I hope this helps!
