UPDATE: - The Puppy Mask is now Base Game. Now there shouldn't be any problems finding it in CAS. ------------------------------------------------------------------------------------------------ I searched for it and found none. So I thought, I make my own Puppy Mask. The mask is tested and you will find it under Hats. If you find any bugs please let me know.   To install it, just move the package file into: Documents \ Electronic Arts \ The Sims 4 \ Mods
