Make villagers increase their prices when a tamed wolf is with you

Villagers will increase their prices and Iron Golems will come to attack the wolf, and when you get the wolf out of village and have it sit down, the villager prices will return to normal.

The idea behind this is that the villagers would be scared of wolves and therefore having a tamed pet wolf with you will trigger the villager gossip mechanic, therefore meaning the prices will increase and the Iron Golems will hunt down the wolf.
