I had a similar problem with an ex neighbor who had several pitts they kept trying to jump my fence or break it down by throwing themselves at it to get to my dog. I had asked several times for him to control his dogs to no avail. I finally informed him if they got in my yard and killed my dog I would be coming after him as it was his responsibility to control the dogs and the dogs didnt didnt know better but he did...he chained them up and moved shortly thereafter....
I guess “cleaning” my shotgun in the yard when he was outside and target practice with plastic primer powered blanks in my pistol caught his attention....the sound of a shotgun slide being racked seems to have universal understanding that crosses all language, cultural and stupidity barriers...
“...the sound of a shotgun slide being racked...”
I’ve “brought several people to Jesus”, myself, with that sound.
