Punch and shear the sheep at the same time (left and right click quickly)
You will get 4 blocks of wool

Code analysis

Based on 1.11.2 decompiled using MCP 9.35 rc1

The problem is that the method net.minecraft.entity.player.EntityPlayer.interactOn(Entity, EnumHand) does not prevent interaction with dying mobs. Or all methods overriding the method net.minecraft.item.Item.itemInteractionForEntity(ItemStack, EntityPlayer, EntityLivingBase, EnumHand) or net.minecraft.entity.EntityLiving.processInteract(EntityPlayer, EnumHand).
