This resourcepack adds Blood to mobs which might have bited...
Mobs added are:
Zombie
Zombie villager

Spider
Disclaimer: The dog does not have a bloody mouth, if you think the dog needs one, then give your suggestion in the comments...
Also currently i have not textured bloody mouths for all the proffessions of the zombie villager, so all the proffessions will look the same.... so if you want a specfic proffesion in a zombie villager, please remove the resource pack, i wlll add blood to the zombie villager proffesion in a few days...

I really appreciate the donations, thanks!!
