I know there is a limit to the number of passive mobs that can be in the game at any one point. (I remember reading somewhere that the number is something around 15, but I'm not sure.) What I'm wondering is how tamed wolves interact with it. For example, take the following scenario: you have 3 less tamed wolves than the passive mob limit. The game logic attempts to spawn 4 chickens.
Will the game just spawn 3 chickens instead? Or will it spawn 4 and remove one of the tamed wolves you currently have? Also, does this mean if you have filled the entire mob limit with tamed wolves, no other passive mobs will be able to spawn?
Best Answer
As of the Minecraft version at the time of writing this...
Tamed wolves are not a passive mob and they do not have any limit, so they will not affect the passive mob limit (because if they were counted in the passive mob limit there would be a limit on the number you can tame.)
Passive mobs (a pig, for example) will NEVER attack you, even if you attack them.
Wolves are actually tame, meaning they follow and protect you.
Short answer:
Tamed wolves do NOT affect the passive mob limit in any way.
