I feel your pain, I have the same issues with neighbors on both sides. I have one that says his dog will kill chickens if she gets a hold of them, but yet he allows her outside , unattended and unsecured in his yard. Which she seizes the opportunity to come to my house. Even though he says she doesn’t leave his property without him knowing about it

. My other neighbor says she’s not responsible for her dog. He only comes
over when she’s out walking and the dog walks with her without a leash. The other day he wondered over into the yard when she was walking. She never came after him, just stood at the road and called the dog’s name. So I blasted it with a garden house jet stream in the face.
I understand animals will do what they do, but I get aggravated with the irresponsible owners. These are older people to who should know responsibilities and be courteous. I have a dog who stays in the backyard and never leaves it unless he’s on a leash. My husband thinks I’m overreacting and I’m being rude about this incident. I’m like “What?????”
