What a shame. Neighbors make all the difference, and yours just sounds like jerk. Keep an eye on him and learn the laws regarding hunting. Make sure he knows you have your eyes on him - don't let him bully you around! Max is an easy target for people like him since dogs don't have many rights, but Max won't be his only target. I understand not wanting to complain but I think he will give you a hard time about anything and everything no matter what. You need to show him that you are the alpha neighbor on the block now!
