Use a paint ball gun on them every time you can , it hurts and non fatal , may drive the dogs home for good
Then explain to the neibors you could have shot them with real bullets .
Be nice .
Explain you don't want to hurt the dogs , but you are paying to hunt and their dogs are ruining your hunting land .
Dog wardens in my area are useless , but if you can catch the dogs she will pick them up .

Better yeat if you can catch the dogs take them right to the dog pound .
