I can not figure out how to make pets attack players (if a player attacks the pet).

This is my config section for zombies:

zombie:
enable: true
tagVisible: true
defaultName: Zombie Pet
interactMenu: true
startFollowDistance: 12
stopFollowDistance: 4
teleportDistance: 40
rideSpeed: 0.2
jumpHeight: 0.6
canFly: false
allow:
riders: true
baby: true
villager: true
force:
baby: false
villager: false
attack:
canAttackPlayers: true
lockRange: 5
ticksBetweenAttacks: 1
loseHealth: true
health: 10
damage: 5

Also, the pet gets teleported as soon as I am about 4 blocks away ... no matter what I have set it to in the config. Is this a known issue?
