Puppy terrified of other dogs

I’ve never had a puppy that has been so afraid of other dogs – all my past little boogers have been super confident She lives with my malamute and is ok with him, but if we’re out on a walk and come close to another dog she freaks out and runs and trembles and cries. Ideas on how I can make it a more comfortable and non-scary so she doesn’t grow up reactive? She’s about 11 or 12 weeks now
