Hey y'all I have an adopted fur son named BODI

I think he's a cane corso mix , and we have thrived together for almost 2 years and he just turned 8! I've tried so many things and haven't been able to do it alone so trying this !! He loves with a pomchii and they get along fine but he's a wild one when he's out and about and triggered by almost any dog but mostly larger ones

I noticed the change in him after he was neutered at an older age and i belive that's what went wrong? I heard older neuters can be an issue but who knows ? Anywys here goes nothings !
