i agree with zazous, use the sss rule ( shoot shovle and shut up), here in la we have a state wide leash law that is not enforced unless the dog becomes a problem, now as far as a dog to protect your birds, i have a curr dog that stays around mine and i will even lock him in the pen with them at night sometimes. now the trick is to raise the pup around the birds from a very young age and thats your best bet, a curr makes a great dog for that but you must raise them around the birds if not they are usuall very ruff on them. i hope this helps but i wouldnt speak anymore about this to your neighbors just act like everything is ok and if the dog keeps causing problems. then one day when no one is around, SSS our job as owners are to feed and care for these animals and that includes protecting them, i hope this helps.
