I know I'd hate it but I'm constantly amazed at how adaptive and smart critters are. For instance, I'd almost swear that the rabbits in our yard know they don't have to run when my doodle is on his leash. Or I'm reminded of my best archery buck. It sounded like a war that afternoon because of the nearby gun club but the bachelor group just kept on picking up white oak acorns like no big deal. So as long as the dogs aren't on your property chasing deer my guess is they only are bothering you. Again though, I'd hate to have neighbors like that and hope it eventually changes for the better for you.
