(compatibility information below)

All mobs have sound effects for every attack they cast and ambient sounds which are made from Vanilla Minecraft with editing on pitch.
This pack requires ModelEngine, MythicMobs. MCPets 2.0.0+ is optional if you want to use the Doghoul as a pet.
Tested with MythicMobs 5.1.2, ModelEngine 3.0.0, MCPets r3.0.1, on spigot 1.18.2.
Versions of spigot may impact sound effects if they are not implemented in the game version you are playing on.
Any issue/questions on this pack can be addressed to me on the discord of MCModels using the ticket system.
