i need some help from anyone thats good with dogs..

my dog is extremely territorial and barks and growls viciously at anybody that comes into my house. this is a medium sized dog with part pit in her, we dont know the other half. pretty much because we saved its life, we found her in a sewage drain christmas eve about 5-6 years ago and it came into our car and we kept him. we are guessing he was abused before we got him.

but i was wondering if anybody had this problem with any of their dogs before...i need to get it to stop being so crazy when i have people are over. we tried introducing it to new people and petting them but if they leave and come back 20 minutes later its the same story. any help is appreciated. thanks.
