Well yorkies should be with there mom until they are 12 weeks because there mother teaches them bite inhibition and it is sounding like your pup wasn't with there mom long enough. Is you other dog not growling or anything? I think your pup is to young for what I would normally suggest which is to fill a squirt bottle with water and squirt her once and say in a firm voice no.
