He just likes chicken!!!! If he's a lab it's breed into him and no stopping him!
I must disagree. Just because a dog breed was developed for something does not mean "its breed into him and no stopping him!". I successfully raised rabbits for years and shared my home with a beagle. Yet, never lost a rabbit to the dog.
This is sadly a case of poor training and animal husbandry. Your neighbor needs to keep control of his animals, period. It has nothing to do with the breed.
